The Whoop 4.0 is finest described as a wearable well being and health tracker. Many individuals liken it to a smartwatch, and it at the moment options in our information to the finest coronary heart fee screens, however it’s in a distinct segment class, with extra established competitors from sensible rings equivalent to Oura and Ultra Human than the wrist-based wearables from the likes of Fitbit or Polar.
It is a subscription primarily based product. You can both pay month-to-month at £27 / $30 per thirty days (for at least 12 months), or join a one-year or two-year subscription at £229 / $239 or £384 / $399 respectively.
It’s a reasonably distinctive product. At first look, the value tag appears loopy for a product that has no GPS, cannot do notifications, cannot do contactless funds and will not play music. In truth, there isn’t any display screen so it will possibly’t even let you know the time.
But to check it to a smartwatch is unfair. It’s not a watch, it is a Whoop; the fourth iteration of a tool that’s worn merely to serve one major objective: Monitor your metrics.
And it does so consistently, each day and evening. It is IP68 waterproof and you’ll even cost it in situ, so that you by no means must take it off. Quite actually, it would not miss a beat.
It tracks your coronary heart fee, coronary heart fee variability, respiratory fee, blood oxygen, pores and skin temperature and extra. Using this “full physiological profile” because the model calls it, it is ready to monitor exercises, monitor sleep, calculate calorie burn, decide day by day stress and an entire host of different nerdy measurements, which I’ll get into.
When you get into the weeds, you possibly can in a short time grow to be overwhelmed by all the information, however its major outputs are available in two easy-to-comprehend scores every day: Recovery and Strain.
It is worn by numerous skilled athletes throughout all method of sports activities. Most notable in biking are the Dutch sensation, Mathieu Van der Poel, and the present males’s Unbound champion Lachlan Morton, however there are lots of of others moreover. A short have a look at thefreshstrap.com informs me that Whoop additionally counts LeBron James, Michael Phelps, Tiger Woods, Cristiano Ronaldo, and Patrick Mahomes amongst its wearers.
I’ve been sporting the Whoop 4.0 for over three years, and we have been by rather a lot collectively. During this time, I’ve used it ‘actively’ – checking the scores every day to tell my behaviours – and ‘passively’ – checking in from time to time for little greater than curiosity.
I’ve worn it alongside a chest-based coronary heart fee monitor for someplace within the area of 1000 exercises. I’ve worn it by a interval of great coaching, by fairly blatant bodily burnout, by a bout of Covid, and even on a handful of very boozy nights out. I’ve joined the notorious ‘1% Club’, and I even wore it for a 270km experience which I did on about 2 hours sleep.
I’ve gone by intervals of loving it and hating it, I even stopped sporting it for some time as a result of it was doing extra hurt than good.
I’m afraid I’m not an expert athlete like Mathieu, Lachlan, LeBron, or Cristiano, however that does imply I’m most likely extra such as you… so this is my trustworthy, clear, all-the-gory-details three-year overview of the Whoop 4.0.
Design and specs
Let’s begin with the bodily attributes and the essential little bit of the Whoop 4.0, which is the small black sensor pod that homes all of the tech: Primarily the 5 LEDs (3 inexperienced, 1 pink, and 1 infrared) and 4 photodiodes.
A fast science lesson for anybody : The sensor works utilizing photoplethysmography (PPG) which basically shines inexperienced LED lights into the pores and skin, and measures no matter gentle is mirrored to find out adjustments in bloodflow, thereby calculating your coronary heart fee, variability and so forth. For completeness, the pink gentle is used for measuring blood oxygen saturation (Sp02).
Image 1 of 4
The pod itself is 33% smaller than the predecessor, at 25.0 mm x 35.97 mm x 10.1 mm. With a strap connected, the entire thing weighs simply 28.5g. It’s unobtrusive, largely snug – though it will possibly generally trigger irritation and soreness, as I’ll get into beneath.
It comes with a typical black strap with a black clasp, however each may be changed with colored aftermarket variations, as per the sand-coloured model proven above. You may also purchase Whoop-branded clothes, together with underwear, shorts, compression tops, sports activities bras, and even Assos bib shorts, which include a small pouch that locations the sensor towards your pores and skin. I’ve used the Assos shorts, because it occurs, although not extensively, however suffice it to say I discovered the center fee information to be correct whereas utilizing them.
As talked about, there isn’t any display screen on board, so all the information being collated is displayed within the Whoop smartphone app.
Strain and restoration
While it’s kind of unfair to simplify the Whoop 4.0 down to 2 capabilities, it is essential to begin by specializing in Strain and Recovery – its two major outputs.
Strain is a rating out of 21, and is constructed all through every day in step with your exercise degree. Crucially, this is not only a reflection of your exercises, however your whole day. Stressful work days, laborious rides, canine walks, and the rest you do this elevates your coronary heart fee will contribute to constructing Strain.
It is constructed utilizing an algorithm, and whereas the specifics of that algorithm aren’t printed, the essential factor to know is that it really works as anticipated. In my three years of use, it has constantly tracked properly with my notion of the day. Days with laborious rides are increased than these with out. Stressful workdays, busy journey days, laborious races and sicknesses are those the place pressure builds extra rapidly.
Recovery is the opposite aspect of the coin and is one other proprietary algorithm-based rating, solely this time it is a share rating out of 100. As you stress your physique, it reacts. For instance, your resting coronary heart fee and respiratory fee will enhance, and your coronary heart fee variability (HRV) will lower. The fee at which it does that is particular person and private, however by monitoring these metrics whilst you sleep, Whoop can be taught your responses and, in flip, calculate how well-recovered you’re and your physique’s readiness to tackle extra pressure the subsequent day.
With these fundamentals in place, Whoop then guides you towards behavioural adjustments to enhance your restoration. Exactly the way it does this, I’ll clarify beneath.
But first, It’s straightforward to get misplaced within the terminology and lose sight of the real-world implications of those day by day figures however whereas Strain – capital S – is a numerical rating, it is very a lot a mirrored image of the pressure – lowercase s – or the stress that you just put in your physique every day.
Likewise, Recovery – capital R – is a share, much like Garmin’s Body Battery, however it’s a reflection of your physique’s state of restoration – lowercase r. I do not see it as a literal gauge of my physique’s capability like my iPhone battery or my automotive’s gas gauge – not least as a result of I’ve by no means hit 100% recovered – however it’s a great indicator of how well-rested I’m and a determine I can use as a information for a way laborious I push my coaching that day.
Sleep monitoring
Forget all of the costly tech equivalent to therapeutic massage weapons, compression clothes and cryotherapy. By far the most important lever most beginner athletes can pull with a purpose to enhance restoration is getting higher sleep, and in my view, that is the place Whoop actually exhibits its value.
Importantly, it is ready to work out once you go to mattress, once you go to sleep, and once you wake within the morning. It’s not minute excellent, and if I get up within the morning however do not get off the bed instantly – eg, I scroll social media for quarter-hour – it will get somewhat blurry. But on the entire, it requires no enter in anyway, which is essential, as in any other case I might positively overlook.
Specific to sleep metrics alone, each evening, Whoop tracks the next:
- Time in mattress
- Sleep latency (the time between getting in mattress and falling asleep)
- Sleep effectivity (time spent asleep divided by time in mattress)
- Sleep and wake occasions
- Your completely different levels of sleep (SWS Deep, REM, Light, Awake)
- How typically you wake per hour
- Sleep consistency (aka your sleep & wake occasions over a four-day interval)
- Hours vs want (want being a calculation of the quantity of sleep you should recuperate totally
- Sleep debt (An accumulation of misplaced sleep over time)
- Sleep efficiency (A calculation of hours divided by want)
- Restorative sleep % (the hours spent in SWS Deep and REM)
Each of those information factors is then graphed out over the current week, previous month, and month-to-month averages over the latest six months, with all historic information accessible too, permitting you to see brief and long-term traits.
From my very own information, I can see that my sleep effectivity is great – averaging round 92%, however that I very not often get as a lot sleep as I want, with a median Sleep Debt of 89 minutes this previous six months. But like most traditional individuals, as an beginner athlete with a busy life and a full time job, I not often have the chance to take naps through the day, so how useful this perception is is up for dialogue.
Sleep planning
For those that could be a little extra proactive of their sleep schedule, the Whoop app helps you propose your evening forward. The app’s Sleep Planner enables you to select a restoration rating for the next day – out of ‘get by at 70%’, ‘carry out at 85%’, or ‘Peak at 100% – and guides you in the direction of the optimum evening’s sleep. This information centres on how a lot sleep you get, and suggests what time you go to mattress and what time you need to wake with a purpose to hit the chosen restoration share.
The Whoop 4.0 additionally has an inbuilt alarm, which makes use of the gadget’s haptic suggestions – vibration – to wake you gently. You can set this for a particular time, or it may be triggered when the app calculates you have had sufficient sleep to hit your pre-selected restoration rating.
Coaching
The Sleep Planner is only one of a wide range of the metrics that the Whoop 4.0 can present steerage and training. In September 2023, the app built-in an AI chatbot which you’ll be able to ask questions on your information, however even with out that, the app is holistically designed to information and educate you.
For instance, inside every of the precise datapoints, there’s an explainer that tells you what it means, what impacts it, the way it’s measured or calculated, and what the implications of a great or dangerous outcome could also be. Further studying is then linked, which takes you to the wealthy database of explainer articles on Whoop’s web site.
And as regards to teaching extra typically, every day it is going to give you an optimum Strain vary for the day on the app’s homepage, alongside day by day behavioural suggestions. Today, for instance, mine reads: “Your optimum Strain vary is 9.6 – 13.6, with a goal of 11.6. Consider a nap, restoration actions or an earlier bedtime to make up for not getting sufficient sleep.”
Data evaluation
Another space the place Whoop proves its value, in my view, is the deep perception it will possibly present through its graphs. The manner it lays out your information over time is absolutely clear and intuitive, and so it affords an at-a-glance understanding of your information.
Take my sleep debt, for instance. The beneath graphs present my sleep debt over the course of per week, a month, and 6 months, and confirms that this week’s information is inside my regular vary. Below the graph, Whoop categorises it and exhibits fairly unequivocally that it thinks I want extra.
Another instance is my coronary heart fee variability. The graphs beneath present that it fluctuates quite a bit from everyday, however over time, the typical stays pretty regular. From January to August 2024, it hovered between 101 and 110, sitting round 107 for probably the most half. But then from August by to November, it exhibits a transparent downward pattern, suggesting my physique wasn’t recovering appropriately, and in hindsight, it is fairly clear I used to be overtraining. I’ll go into this in somewhat extra element beneath.
Journalling
The different facet of Whoop’s teaching is the way it integrates day by day journaling into the method.
To set this up, you’ll initially select a couple of behaviours (from a really lengthy record of choices) that you just want to monitor. Then every morning, a popup seems asking whether or not you accomplished your chosen behaviours every day. These vary from “did you’re taking a multivitamin” to “did you’re employed late” and “did you drink alcohol” – there are lots of of others moreover.
For a little bit of enjoyable, listed below are a few of the extra uncommon behaviours you possibly can monitor: Did you obtain acupuncture; did you sleep with a cat (or a canine) within the bed room; did you attempt to conceive a baby; did you’re taking ketamine (or marijuana, LSD or magic mushrooms); did you masturbate (or interact in sexual exercise); did you expertise signs of monkeypox; and fairly merely… what’s your relationship standing?
Over time, as you fill in your journal every day and log your varied chosen behaviours, Whoop calculates their impact in your restoration. Using its advanced algorithms, it’s in a position to select correlations between your behaviours and your restoration scores, and assign a impression share.
For instance, for me, every time I’ve taken a multivitamin, my following day’s restoration rating has been on common 1% higher than the times I have never. Likewise, on the times I take a sizzling bathe earlier than mattress, my subsequent restoration has been a median of 6% decrease.
I feel this fails to think about some actually essential context, although. If I bathe earlier than mattress, it is seemingly as a result of I did a very strenuous night indoor experience, which most likely means my day Strain is increased, and I get to mattress a bit later than typical. I might predict that is the true purpose for my lowered restoration, somewhat than the bathe itself.
Similarly, Whoop thinks that working late has a optimistic impression on my restoration. This is as a result of after I work late, I nearly at all times skip my night experience and in flip my Strain is decrease and restoration is less complicated.
My experiences
In this part, I need to get into somewhat extra element about my private experiences utilizing Whoop and the Whoop 4.0 strap. Here I’ll speak in regards to the day-to-day of sporting and residing with it, overlaying consolation, exercise coronary heart fee accuracy and extra.
I’ll additionally dive into a few of the extra apparent cases of excessive pressure or poor restoration, equivalent to after I wore it for a 270km experience on 2 hours sleep, after I contracted Covid-19, after I joined the notorious 1% Club, and the way it tracked – however did not warn me – that I used to be overtraining.
Day to day
The day-to-day expertise of proudly owning a Whoop 4.0 is seamless. As I discussed above, it robotically notices once you go to mattress and get up, and it does the identical for exercises so there isn’t any want to recollect to enter your exercises or log something. Daily journal apart, which you’ll be able to ignore, it wants no enter in anyway moreover remembering to cost it.
It’s actually intelligent at understanding what sort of exercise you probably did too, to the purpose the place it will possibly even work out the distinction between a ‘Spin’ and a ‘Cycling’, or as within the picture above, a ‘Duathlon’ and a ‘Cycling’ (I rode to and from the occasion). At first, it is going to get issues blended up, however after round per week of correcting the errors, it learns.
It’s largely snug, however I’ll say that given you should put on it tight sufficient that it sits snugly towards your arm, it will possibly generally trigger irritation, redness, and soreness. This is very prevalent in heat situations, presumably a results of sweat build-up or growth/irritation.
As talked about, charging is completed on the wrist through a intelligent piggyback wi-fi charger that clips onto the sensor. The charger itself is charged through USB-C, and carries sufficient for one cost of the Whoop itself. That then lasts someplace within the area of 5 days, and after this level, I typically realise I forgot to cost the charger! My idiocy apart, the entire course of is absolutely intelligent and straightforward.
Heart fee accuracy
I’ve been sporting the Whoop 4.0 because it launched, and in that point, I’ve most likely ridden my bike near a thousand occasions, every time utilizing a chest-based coronary heart fee monitor alongside the Whoop strap.
I’ve additionally often used the ‘coronary heart fee broadcast’ perform, which permits third celebration units (bike computer systems, laptops and so forth) to make use of the center fee information from the Whoop itself.
Here are a few examples of the Whoop coronary heart fee information in exercise in comparison with a chest-based coronary heart fee monitor.
Image 1 of 2
Here, I accomplished an over-under Threshold exercise on TrainerRoad. According to the Garmin HRM Dual I used, I averaged 144bpm, with a max of 181. The corresponding Whoop coronary heart fee graph follows an analogous graph, with a barely decrease common of 139bpm, maxing out at 177.
Image 1 of 2
Here, in additional of an on-off Vo2 Max exercise, my Wahoo Trackr confirmed a median of 137bpm, with a max of 176. Again, the Whoop information follows an analogous graph, proving the Whoop 4.0 is able to noticing fast adjustments in coronary heart fee. My common right here is as soon as once more decrease, at 128bpm, however the most of 175 could be very shut.
Image 1 of 2
Choosing a better experience – each for me and for the center fee sensors – this 90-minute endurance experience from July had my coronary heart at 141bpm common, maxxing out at 163. Whoop’s information as soon as once more adopted the identical graph, on this case a gradual enhance. It averaged barely decrease at 137bpm, and on this case, peaked at the exact same 163.
It’s an analogous pattern all through all exercises, each current and historic. The common tends to be barely decrease than chest-based screens, however the highs are captured appropriately, as are the adjustments.

Sleep accuracy
The accuracy of its sleep monitoring is one other factor Whoop does rather well, though not with out a few caveats.
I’ve worn the Whoop alongside Garmin, Apple and Polar watches. I’ve by no means worn all 4 directly, however whereas time in mattress is essentially correct throughout all units, I discovered my HRV determine diverse from gadget to gadget (presumably primarily based on when within the evening it will get measured).
An instance of this may be seen within the two graphs above. Here I wore each the Apple Watch Ultra 2 and the Whoop 4.0 collectively (on separate wrists) for a month. According to Apple Health, my HRV averaged 85 milliseconds, whereas on Whoop, it was 106. I do not suppose the accuracy is definitely all that essential as a lot because the consistency. As lengthy as you stick to 1 gadget, the information needs to be helpful. Flit between units and your information shall be equally erratic… like doing an FTP take a look at with one energy meter and coaching with one other. Or weighing your self at completely different occasions of day.
The sleep levels (Deep, REM and so forth) are diverse much more so throughout units, and with that, I have a tendency to not fear about how a lot time I spend in every. It’s not one thing I can simply management anyway.
But as for what time I bought into mattress, what time I nodded off, and what time I awoke, I discovered Whoop’s estimate was most constantly correct. If you already personal a type of watches, the distinction alone is not value the additional $30 a month, however when you’re coming at this downside recent, it is a promoting level in favour of Whoop for certain.
COVID-19 in Whoop phrases
In August 2022, I used to be invited to Switzerland to experience Chasing Cancellara, a 270km sportive from Zurich to Zermatt. It was a brutal day, made considerably extra disagreeable by the 02:00AM begin.
The evening earlier than, I went to mattress at 8pm, lay awake for round two hours (rattling you, circadian rhythm) and ultimately fell asleep at 22:39 (so says Whoop). My alarm sounded at 00:30, and Whoop reckons inside this time, I managed 1 hour and 44 minutes of sleep. My restoration rating was 7%.
Up and in package, I headed over to the close by begin, earlier than driving for 13 hours, ending at round 3PM. My greatest ever day was good for a 20.7 on the Strain scale. But the subsequent evening’s sleep was no higher. A late bus from Zermatt again to Zurich meant I did not get again to my lodge till 11pm, and the next day I used to be up at 6am for an early flight dwelling. Despite a comparable eon – 4 entire hours – of sleep, my earlier day’s pressure meant my restoration was simply 4%.
The subsequent day, I managed an hour-long nap earlier than a seven-hour sleep, and although my restoration was bettering, it had solely jumped to 24%.
I then started to really feel sick. A optimistic COVID take a look at confirmed the worst, and regardless of doing completely nothing for 2 days, my subsequent two restoration scores had been 10% and 12% respectively.
Interestingly, throughout as of late, my resting coronary heart fee rose from round 40 to the mid-50s. My HRV dropped from the standard ~110 to the 60s. My respiratory fee shot from a constant 13.6rpm to 17.5. And regardless of spending the day in mattress, I managed to hit a Strain of 13.5 on the Tuesday.
The 1% membership! Whoop vs numerous alchohol
But that wasn’t my worst restoration ever. I’m a proud (ish) member of the notorious 1% Club – that’s, hitting a restoration rating of 1%.
I do not drink rather a lot, even much less so now I can see what impact it has on my physique, however I bought married in 2024 and so in February, it was my stag do (bachelor’s celebration for these within the USA). The first evening of mentioned stag do was a boozy one.
The most fascinating half, nevertheless, is the ‘stress’ I accrued whereas asleep. In the 5 hours of sleep I managed, it was nearly solely spent within the excessive stress zone (a measure of movement, HRV and coronary heart fee). My respiratory fee shot as much as 15.9rpm, my resting coronary heart fee jumped to 63, and my HRV dropped to 33 – that is worse than after I had Covid!
I admire that tales of me being sick and getting drunk have not actually added something of actual worth to this overview, however I’ve included them for a purpose.
Amid regular day by day life, once you’re not pushing your self too laborious and you are not bodily unwell, the restoration share would not at all times replicate how you are feeling. Some days, you are feeling nice, you get up with a spring in your step after which have a look at the app to discover a yellow restoration rating (34 to 66%). The subsequent day, you would possibly get a tough evening’s sleep and get up to a inexperienced rating (67 to 100%).
It’s fascinating, and considerably reassuring of its accuracy, to see the pink scores (1 to 33%) once you’re actually not doing properly.
Why I ended sporting the Whoop strap
That leads me properly to the rationale I ended sporting it for a couple of months in 2023.
Given the restoration scores do not at all times replicate how you are feeling, you possibly can go certainly one of two methods. You can lose belief within the information, or you possibly can put an excessive amount of belief in it and lose sight of the massive image, which is what occurred to me in 2023.
Context: I did not actually have a purpose or an occasion to concentrate on in 2023, and so my coaching lacked course or focus. Without that, I relied on motivation to experience.
On days the place I awoke feeling drained, I might select to not experience. On the times the place I woke feeling fantastic, however with a poor restoration rating, it was a right away excuse – ideas equivalent to “I most likely should not experience right this moment, I’m clearly not rested sufficient from the final experience,” would undergo my thoughts, and earlier than I knew it, I used to be laying on the couch as soon as once more, feeling responsible.
This was clearly my very own poor psychological well being, somewhat than one thing that Whoop wants to enhance on, however I feel it is an essential reminder that like all information, Whoop is just there to tell the massive image. It shouldn’t be the massive image in itself.
For me, these yellow restoration days had been extra seemingly the outcomes of late nights watching TV, the stress of getting a pet in the home and her midnight bathroom journeys to the backyard, earlier begins to stroll the canines earlier than work, a poor weight-reduction plan, and even perhaps my random, staccato coaching.
Fast ahead to 2024, and my coaching discovered its focus as soon as once more. A half marathon in March, adopted by the Gralloch gravel race in May after which Gravel Masters National Championships in August gave me objectives to concentrate on, which in flip gave me motivation to coach and a routine as soon as once more. I began sporting the Whoop once more later in 2023, and regardless of the rise in coaching load, my restoration scores are arguably extra inexperienced than earlier than.
What’s completely different, nevertheless, is that I now take the rating as a small sense examine of how I already really feel, somewhat than letting it inform me how I ought to really feel.
I mix it with the broader context of my current coaching, how I’ve been sleeping, my weight-reduction plan, hydration, and extra. I search for longer-standing traits, somewhat than day-to-day swings. If it is yellow on someday, I’ll make an additional effort to get to mattress sooner the subsequent evening. That’s not at all times potential, however a minimum of I’m able to rationalise the decrease restoration and proceed to comply with my coaching plan. If I discover persistent dangerous information, equivalent to a excessive resting coronary heart fee or low HRV for a couple of days in a row, then I’d take a relaxation day. Importantly, I prepare extra now than I did earlier than, I really feel higher for it mentally, and by the information, I’m no worse off.
What does overtraining appear like within the Whoop app?
With that each one mentioned, within the latter half of 2024, I went the opposite manner barely, and ignored the information an excessive amount of.
I’d had certainly one of my finest seasons in a very long time. I educated laborious however properly, and I had some good outcomes, so in October, after I ought to have had a relaxation, my motivation for 2025 was sky excessive. I took per week off the bike and began coaching laborious once more. I used to be fantastic for a month, however then in November I bought sick, and I carried that sickness by December, and nonetheless really feel the impacts of it now in early January.
Looking again at my HRV information, it is clear I used to be overdoing it. My HRV tends to hover at a median of round 100 to 110ms. But in September it was 98, October it was 90, and by November it has dropped to 86. It was on a transparent downward pattern, and had I seen, I might have taken a bit extra day without work.
Part of me wonders whether or not Whoop ought to have been in a position to spot this pattern and flag it in late October, however perhaps that is on me.
Is Whoop good worth?
For $30 a month, would I say that Whoop is nice worth? As at all times, it relies upon.
It depends upon whether or not you have already got a smartwatch that may provide a few of the similar capabilities, and what your objectives are, how properly you possibly can contextualise the information within the huge image, and in how a lot of a place you’re to regulate your life-style to motion the insights it supplies.
If you need one thing that passively tracks your metrics, then an Apple Watch or a Garmin smartwatch would nearly definitely be sufficient, whereas additionally providing a large number of different capabilities. They don’t have any month-to-month charge both, and so their excessive preliminary outlay would ultimately steadiness out.
Most importantly although, when you’re an expert athlete (or a devoted beginner), and also you’re in a position to regulate your life-style, then the depth of knowledge and perception that Whoop can present may very well be extraordinarily useful.
Final verdict: Do I like to recommend the Whoop 4.0?
Overall, the Whoop 4.0 is a distinct segment and fairly distinctive product. It’s geared toward normal health and well being, however in my view, it is going to discover most favour amongst athletes trying to eke out efficiency positive factors.
The time period biohacking will get thrown round rather a lot, and though Whoop would most likely fall beneath that class, it feels to me extra like a device that gives real and useful perception into your wholesome and unhealthy habits, guiding you gently towards the nice ones and away from the dangerous.
The coronary heart fee accuracy is sufficient that I might be pleased to interchange my typical chest-based coronary heart fee monitor with this alone, and though it would not embody a show, inform the time or provide any of the conventional capabilities of a smartwatch, I do not need it to.
And now that this long-overdue overview is written, I’ll carry on sporting the Whoop 4.0.

Connectivity | Bluetooth connectivity to smartphone solely, however this may be broadcast to 3rd celebration units for actual time monitoring on bike pc or laptop computer | 8/10 |
Accuracy | While the typical coronary heart fee determine tends to be decrease than chest-based screens, the peaks are sometimes related and its means to comply with the rises and falls is nice. | 8/10 |
