Love my Whoop!
Great health and fitness tracker overall! Tracks much better than my old Pixel watch, and I appreciate that it prioritizes battery life over a display — hoping v5 will be even more compact!The app is really good, although I guess it has to be since the device has no display. I wear mine daily and have no issues with durability after about 10 months of use.I would recommend a bicep band or something else to give your wrist a break. I have their compression shorts as well, which are surprisingly nice (and they have good discounts around turkey time).The band it ships with is nice, but does get funky after a while. I stopped wearing mine in the shower, which helped, but I’d also consider get a second band to switch things up.Lastly, HSA! I originally had a trial with Whoop, but ended up buying on Amazon to use my HSA card to pay for it. You can do the same on Whoop’s site, but you’ll have to reimburse yourself — so super nice to be able to use your card on Amazon.

WHOOP Life!
Amazing product. You have to wear it to realize how much information it can give you and how informative it is about your daily routine. Great for workouts. Great for knowing your sleep needs, recovery needs, total strain and stress during your day and gives you hints as to how to improve your rates.

Hot Garbage
** update March 9. I completed a 5.1 mile hike with an average pace of 3.5 mph. What does the whoop say? 271 calories. If you look at the internet. For my weight and that pace the calorie burn is between 550 and 620 kcal. But whoop, whoop says 271. I have never used a more inaccurate unreliable piece of trash.**update 10/19 deducting yet another star. The device is basically worthless. Sad because itâs a good idea and is expensive. Did a 3 mile walk this morning to warm up. Iâm 190# man. Walking a flat mile even at a somewhat leisurely pace costs my body 110-125Kcal. Wearing the whoop and my Apple Watch. Watch records 350 kcal burned. The whoopâ¦123. Both set to âwalkingâ worn on opposite wrists. 123 vs 350. The device is absolute garbage. Avoid it.** update 9/12. Deducting another starI really wanted to love this device and maybe mine is just a lemon. The readings, specifically heart rate which is one of the only things I am really truly interested in are so far from accurate that the device is almost worthless. This is disappointing because the device is both expensive and has an expensive subscription associated with it. I did a hard workout again wearing both my Apple Watch and my WHOOP. Was 30 minute EMOM. Alternating rounds of 10 double unders And 15 Russian kettlebell swings at 80#. So at least for me a metabolically demanding workout. During the double unders Apple Watch has my heart rate pegged between 165 and 175 Which makes sense based on the activity and how I feel (like Iâm sprinting). The average for the whole Apple device was just under 150 BPM. Conversely, the whoop worn on my other wrist Shows my heart rate during the double-unders at between 96 and 120 (Which again is moronic) And my heart rate for the overall workout at 127. Only after I started my cool down and my heart rate dropped did the Apple Watch and the WHOOP come into line. I wonder if the WHOOP is just too imprecise as a piece of hardware so when your heart rate is extremely fast itâs missing beats, Iâm just theorizing but itâs disappointing in any event. The AI WHOOP support is also completely worthless. canned responses and useless troubleshooting pages. I donât know what device to recommend, but if youâre serious about your data, this ainât it**update 8/25.I wore my my Apple Watch Ultra and Whoop at the same time today (albeit Whoop on right arm Apple Watch on left) as discussed in the main review below. I set both devices to âfunctional strengthâ and then went about my work out. Main part of the work out was 30 minutes. During that time. The whoop registered 241 cals burned and an avg heart rate of 119. The Apple registered 327 cals burned and an average heart rate of 129. I also noticed that during certain periods of the session, the Apple registered my heart rate at 145 bpm and the Whoop 107. Iâve been an athlete my whole life I know what 107 feels like, and I know what 145 feels like. I also at that point timed my pulse and got 140. Not sure if the whoop reflects a high degree of latency (claims it doesnât) but that reading is way way off. Could also account for the meaningful deviation in calories. I pinged the whoop chat bot to ask. It was useless. Offered a lot of semi science mumbo jumbo about strain calculations. Iâm deducting another star.I work out daily. Have for the last decade and a half. When I was younger it was conditioning for various combat sports. Now that Iâm in my 40s itâs conditioning for the combat sport that is life. I still get after it pretty hard every day, and in the last few years have become interested in tracking biometrics. It started with various Fitbit devices, which were super limited, moving up to the pretty good Garmin instinct solar, to The OK Apple Watch Ultra (you can find my review on here somewhere) And now the Whoop. The reason I wanted to move away from the Apple Watch is threefold (although candidly the device is deeply flawed in general). 1) Itâs far too busy, too much going on, too many notifications too much buzzing 2) The battery life sucks (2.5 days max) and 3) I really like watches, actual watches, aesthetically I think the Apple Watch Ultra is just awful. The WHOOP checks all the boxes. It has no screen or buttons, it does not buzz. It is extremely minimalist. It is very lightweight And comfortable. Battery life is about a week, However, in a bit of pretty ingenious engineering, you donât take it off to charge it. You charge a small battery pack That Whoop wears like a backpack on your wrist. So every few days I just slap that on after my workout the Whoop charges fully in a manner of minutes and we go about our day. The Whoop interface is ok. Its fine. I think thereâs a lot of data in there and Iâm just getting used to accessing it. I like that itâs sleep and recovery focused. Every day I get a grade for my sleep quality (usually not great) And a related grade level of ârecoveryâ from yesterday. I donât pretend to know the science behind the recovery statistics, however directionally they are in line with the way my body feels in the morning and throughout the day. The major flaw in the WHOOP design that I have encountered so far in its âstrainâ calculations. Once you wear the device for a few days It starts to make customize recommendations for how hard you should push yourself physically given your recovery level. Thatâs fine, Although I tend to just move through my schedule of splits and conditioning irrespective of what the Whoop says. What I have observed though, and it annoys me, is that the calorie calculations are way off relative to every other device Iâve ever used. For a given activity I think theyâre probably 20 to 30% low relative to the Apple and 40% low relative to the Garmin. Theyâre also internally contradictory. Here is an example: today was a conditioning day. I did a pretty hard workout which consisted of timed sets of pull-ups, push-ups, and jump squats. Itâs a 30 minute timer. You do seven pull-ups 15 push-ups and 20 squats per minute and then rest the next minute, etc. So you wind up doing the high volume of movements. And your heart rate is quite elevated. My Apple Watch records this session at a bit over 400 calories. My WHOOP records it at 258 calories. Iâm not sure which is right, But I will say that the WHOOP has a âstrainâ score, which is roughly a measure of how hard your body is working during the exercise. Before the exercise âprocessedâ my score 8.2, with a heart rate averaging in the 130s with peaks in the low 160s. When I finish the exercise and added in the movements as prompted by the WHOOP It recalculates the strain score to 16.8. Reflecting the work rate associated with the movements I was doing. So the strain increased to almost double to accommodate the amount of work done during the session. Why did the amount of calories calculated by the WHOOP not increase? Exertion requires thermodynamic energy; my strain went up because I was doing more work, work = energy output= calories. So that is a bit bit silly. Overall Iâm still pretty happy and the actual numbers donât matter, although little sloppy nits like this bother me. Maybe theyâll work it out in a future software release.

D1 College Athlete Approved!
My son is a D1 college athlete and this is his favorite tracking device for his health, recovery, sleep, etc. It tells him heâs sick before he feels heâs sick! Crazy! He can wear it on his ankle or wrist. Great value and very durable. Light weight.

Tons of useable data !!
By far the best fitness trackers Iâve ever owned. Tons of data to view, analyze and adjust sleep, nutrition and workouts for better health and goal gains.

Whoop Band is too good
Good Activity monitoring , value for money. If followed properly – can work towards healthy life style.
Arielle Greene –
Husband loves this! He threw away his Fitbit!
This is an amazing product that is completely worth it. Its cordless charging is a game changer. My husband never takes it off. Itâs smaller than the bigger Apple Watch and it doesnât irritate my husbandâs wrist like the Fitbit did over time. It offers so much insight to my husbandâs sleep patterns and workout routine a well. Highly Recommend!

Serious problem with sensors accuracy
My whoop tracks sleep pretty well, but as soon as I do any physical activity (as simple as walking) it starts messing up and Heart Rate keeps fluctuating very erratically. I have to keep trying to adjust the band and reposition it so it reads more accurately. With inaccurate physical activity tracking, that’s inaccurate Strain logging in, and that’s consequently inaccurate stress and recovery measuring. All in all I sadly cannot trust any of the metrics I get out of it.I compared it to my Garmin watch which I wear continuously on my other wrist and it is always quite off by sometimes as much as 20 bpm more (or less) than the Garmin. I did also the exercise on purpose with my Fitbit which I had stopped wearing to use the Whoop and same result: the Whoop is always pretty off by a considerable difference in bpm.I voluntarily did the exercise several times to compare the Fitbit with the Garmin and they are synced like a charm, hardly a couple of bpm difference between them or a second or 2 of delays between them. The Whoop issue is a whole other level!I unfortunately missed the support window of 3 months which I was not aware of until i finally decided I need to get in touch with the seller for a solution… Overall pretty disappointed with my experience, and although I had heard some good opinion about it, there are not much people in KSA that are also wearing one to compare… not sure what I can do anymore about it.

I bought this as a birthday gift for my husband. He is quite happy with the product. How good it is in terms of tracking and performance will only be known after some data is collected and compared with his other device. Hope this will help him understand his recovery patterns after long runs.
VikResh –
Coming from the world of Fitbit, that used to malfunction quite often and would be useless. This one is good. The tracking is great and the insights one gets is quite profound. The only issue, if it’s even one, is the band. Wish they had a easy way to use the unit. All good otherwise and am quite pleased.
