- Reviewed in the United States on April 16, 2025I was hesitant in buying this due to some of the poor reviews. The device is excellent for anyone who is interested in understanding the quality of their sleep and recovery. While I've only had it for less than 2 weeks, it's helped me to recognize when to push myself harder and when I should take a recovery day. I love the sleep data and personalized (AI) suggestions based on your health goals and the that the habits that you record. The starter band kinda sucks, so I'd recommend budgeting for one if you plan to keep your whoop. Also, I'm so pleased that the device works with AW and Apple Health. I don't think it's an either / or but more that the devices compliment one another.
- Reviewed in the United States on May 3, 2025Love the whoop. It gives me great feedback for my sleep, workouts, and several other analytics. I like the fact I don’t have to take it off to charge and the battery life is good. It fits well and is lightweight. I find it to be a great tool.
- Reviewed in the United States on August 22, 2024** 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 it’s a good idea and is expensive. Did a 3 mile walk this morning to warm up. I’m 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 whoop…123. Both set to “walking” worn on opposite wrists. 123 vs 350. The device is absolute garbage. Avoid it.
** update 9/12. Deducting another star
I 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 I’m 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 it’s missing beats, I’m just theorizing but it’s disappointing in any event. The AI WHOOP support is also completely worthless. canned responses and useless troubleshooting pages. I don’t know what device to recommend, but if you’re serious about your data, this ain’t 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 “functional strength” 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. I’ve 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 doesn’t) 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. I’m 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 I’m in my 40s it’s 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) It’s 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 don’t 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 there’s a lot of data in there and I’m just getting used to accessing it. I like that it’s sleep and recovery focused. Every day I get a grade for my sleep quality (usually not great) And a related grade level of “recovery” from yesterday. I don’t 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 “strain” 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. That’s 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 I’ve ever used. For a given activity I think they’re probably 20 to 30% low relative to the Apple and 40% low relative to the Garmin. They’re 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. It’s 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. I’m not sure which is right, But I will say that the WHOOP has a “strain” score, which is roughly a measure of how hard your body is working during the exercise. Before the exercise “processed” 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 I’m still pretty happy and the actual numbers don’t matter, although little sloppy nits like this bother me. Maybe they’ll work it out in a future software release.
- Reviewed in the United States on April 15, 2025Fantastic product. I've been wearing every day for 3 months. Great insights. Also, it has made me realize how poor my recovery is whenever I drink alcohol and has basically paid for itself in money saved from drinks.
I have recommended it to anyone who has asked about it or in the market.
- Reviewed in the United States on April 21, 2025I love mine. I got it strictly for tracking my sleep and heart rate but have now learned of many more features that are helping be more attentive. I makes point to journal in the app every night and since having mine, I have been unknowingly watching my health more. The sleep tracker is also the best sleep tracker I’ve ever had, and I’ve had about all of them. All the poor reviews almost had me go a different route (oura ring since got my wife one; but for menstrual tracking I think oura is better from what my wife says) but decided to try it since my Apple Watch is very unreliable and dead before I’m home from work even though only a year old. Needed a tracker specifically for my health and sleep, and this does that. From what I can tell from the poor reviews, it seems those making the comments are either not very technically inclined or just havent taken the time to do the walkthrough of the app. It allows you to customize just about anything. Yes, the first 7 days it will be limited as it’s calibrating but for accuracy it must do that. I was also surprised how much I like the standard band. I forget I’m wearing unlike my Apple Watch. I wear both at the same time all day and keep my whoop on forever since you can charge from anywhere with the battery pack. That’s a pretty cool feature. I would just say…. This is not a $5k medical tracker for serious health concerns, if you’re healthy or relatively healthy this will be perfect for tracking your day to day and night to night. Definitely worth the money. And I have no problem putting in my CC at sign up even with a paid 12m membership, at the end of the day you’re paying for the software of the device and app, that’s where the magic is, not the band and device. It is worth every penny!!!!
- Reviewed in the United States on March 23, 2025I'm really enjoying the product and software for my fitness journey. Subscription price feels a little high, but overall I am satisfied. The sub price is the only reason I didn't give 5 stars. I love that I can charge on the go or in the shower, it's really convenient not needing to take the band off. Also, why are the bands so expensive? I want more colors, but not at the price point they ask.

4.0 out of 5 stars Good product and easy to understand
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.

5.0 out of 5 stars Looks good
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.

5.0 out of 5 stars A Game-Changer for Serious Athletes
I bought the Whoop band for my 18-year-old son, who plays high-level hockey, and it has truly taken his fitness to the next level. I was skeptical at first—wondering why he didn’t just want an Apple Watch or Fitbit, which track fitness and offer other features—but after seeing the detailed analytics this band provides, I’m blown away. It’s far more advanced than anything I’ve seen with my own Apple Watch or Fitbit.
One of the coolest features is that it syncs with his teammates, allowing them to compete and compare who worked the hardest during practices and games. It also tracks recovery status, which has been a game-changer—he’s getting more rest now instead of staying out late, and I love that.
If you have an athlete who’s serious about their fitness and performance, I highly recommend the Whoop band. It’s not just a fitness tracker—it’s a tool for real improvement.
