"It’s been great for balancing strain/recovery/sleep. ... so having Whoop tell me which days I should go harder or lighter has made such a difference in my training regiment!"
"If you are looking for highly accurate HRV and recovery information, you should use WHOOP. ... whoop provides more accurate data. ... Whoop main focus on recovery and vitals ... according to him whoop provides more accurate data. ... If you are really after the best data on recovery, whoop is imho the best offer on the market."

"Support had me go through all the usual troubleshooting steps — no fix. ... I was told a replacement had been “processed” and would ship. ... It’s now been nearly two weeks and my order is still showing as “processing”. ... I’ve exchanged 24+ emails with Support. The replies are all scripted apologies and vague “please wait” responses. ... Their site promises 3–5 days for new orders, yet for a replacement I’ve paid almost $500 for, I’ve received nothing. ... I’ve asked for a refund policy and escalation, but I keep getting ignored."
"Horrible mistake. This has completely bricked my account. ... I’ve been on the phone with WHOOP several times and we’ve been emailing over the last week trying to get back into my account, and there seems to be no fix available whatsoever. ... I can’t get on the account using my primary email, I can’t get on the account using my secondary email, and WHOOP recommended that I just make a new email address, stating that this would fix the issue. So I made a random email JUST for WHOOP, and they responded saying they updated the email address and that I should be able to login. I cannot. The account is still bricked, and I still cannot login. ... They’re also refusing to refund my money (even though I started my $300 membership just 57 days ago) but offered me a 1 month membership credit ON THE ACCOUNT THAT I CANNOT ACCESS."
"My wife got burned by her Whoop in a similar fashion last year and they did nothing besides deny, deny, deny then try to cancel her membership. ... there was a whoop burn imprinted into my wife's wrist that perfectly matches the whoop she was wearing on the same wrist. ... They said things like "their sensor logs indicated there was never any indication there was an issue with the whoop device". ... Then they went no contact."

"HR reading on Whoop are known for being absolutely aweful. ... Better having an accurate reading every 5 minutes than multiple bad readings every seconds. ... Whoop has awesome software and data analysis, but makes it somehow unusable because of bad hr data in. ... If HR accuracy is not a problem for you, and only follow "very general trends", yeah Whoop is a cool product. But if you are at some minimal point serious about HR accuracy, for real sport / performance / improvment, you cannot relly on it. ... If a Polar device, Garmin, apple watch says it's at 80 with readings every minute or so, and whoop says 65 every seconds, your "constant readings" are not worth anything. Garbage in, garbage out. ... Even counting it manually with a timer and my finger on my neck would be more accurate. ... their linear HR sensors are poor quality, and not the ideal way of positioning them (VS circular patern)."
"I had Whoop for three months and it started showing a very bad data. Like catastrophicly bad. ... Bought Polar chest strap to check my HRV, it was VERY different and was showing me my normal data, data that whoop originally showed to me as well until three months into use it stopped."
"The thing whoop is giving me is wildly inaccurate HR readings. ... Did a casual bike ride with my child yesterday afternoon and whoop gave me a 187 high HR. This was a really slow like 4 block bike ride. ... AW said 108hr peak. Ive biked hard, ran as hard as possible doing max HR tests with my H10 chest strap and never hit above high 160s. ... Im not sure whats going on but its been doing this type of odd HR readings all week."

"the muscular load, the cardio/muscular split, and the intensity didn’t match my perception at all ... and it doesn’t show history/trends per exercise or velocity ... I stopped using it completely, waiting for them to release improvements (which never came - then I cancelled my membership). ... Currently, I don't see how the whoop strength trainer would be *useful* for strength / hypertrophy."
"HRV isn’t a reliable metric of readiness for strength training, to adjust your strength training sessions on a daily basis, based on the current overall body of research ... that wouldn’t really work if the main goal was to maximize strength (and/or muscle growth). ... For my strength training, I'd basically ignore HRV (and whoop recovery / day strain recommendation)"
"the data is ultra inaccurate. Like really. Not even close."

"This was the promise: You pay for a super-expensive subscription. You don't get enough value for it every month, but when we upgrade our hardware, you get it for free. ... This is what they did: They created a "slightly upgraded" version and called it Whoop 5. And they also created an "actually, significantly upgraded" version, and they called it Whoop MG. And they decided that the "actually upgraded" version will not be free for the people who believed the company's promise and paid the overpriced subscription for years. Instead, if you want the "actually upgraded" version, you will have to pay even more. ... I can't trust you not to release a paywalled Whoop 6 after I upgrade."

honestly not sure why a lot of the reviews here are negative, the only thad thing i could say is the steps tracker but it’s also the beta version🤷🏽♂️and im not really worried about steps. I highly recommend whoop to everyone so welcome to the team💪🏽
r/whoop • Ordered a whoop band despite the negative reviews here ->My HONEST review of the 5 MG. So to start with, I'm not an athlete, I go to the gym every now and again, and try to stay fairly active. What I am... is a tech guy, a stats guy, someone who loves data. Last year, I discovered the Whoop 4 after seeing ads for it on social. I spent most of the year wearing one until I had some health problems in December. I had to have some tests, and one critical piece of information that would have been useful was a baseline ECG reading. I couldn't provide it, and it actually hindered my recovery. That was the day I stopped wearing a Whoop, and bought an Apple Watch. Fast forward to today. My MG arrived a few days ago and I'm now back to all the data I used to love with the addition of an ECG and BP. I'll start with the BP reading. We have a blood pressure machine at home so it was straight forward for me to calibrate the MG. Initial results suggest it's pretty accurate, but time will tell. I'll do comparisons over the next few months. Not onto the ECG. Look.. it's ok, it's not as good as Apple's. It's harder to use, seems to be fairly accurate but can give some odd results if not held very specifically. It does the job for me. Let's talk about the quality of the band and device. The device feels premium, the band and clasp feel cheap AF. Because, let's be real with ourselves, they ARE cheap. The material is cheap. The finish isn't particularly amazing. When third parties produce an MG band I'll be first to try them. The packaging felt cheap, it didn't feel expensive at all. I often keep my tech boxes, I won't be keeping this. As for everything else, the app, the functionality, well yeah it's what I loved before. Now... price. I pay monthly. I pay £39. Is it worth that? No, that's pretty ridiculous in my eyes. Am I willing to pay it? Yeah.. because no other device gives me the distraction free data I crave. Do I agree with all the moaning here and concerns? Yeah, you're all valid, Whoop took the piss and have moved the goalposts. But I'm a sucker for tech, and most of you are too, so even though I disagree with their practices we're all going to fall in line and consume. Let's be honest. Short version: It's a good device, new features are decent, it's overpriced but unique to the market.
r/whoop • My HONEST review of the 5 MG. ->I remember buying my whoop 4 and watching all the reviews beforehand. Every video told me that the new model will be free of charge. Decided to buy the whoop, knowing the whoop 5 will come out shorty. I’m cancelling for sure
r/whoop • Whoopgate — The receipts ->I just got a Garmin a few days ago. And I use it mainly for runs. Need to track pace, cadence etc. I only wear it when I run. I know I probably went overboard with that purchase, but for sleep/recovery etc I use the Whoop. Best combo ever.
r/whoop • Garmin forerunner 965 + whoop 4.0 ->That is the rechargeable battery pack, typically attached when it is off wrist to recharge for a couple hours. The Whoop itself is integrated with the band/strap and very slim. https://preview.redd.it/p5k2ovy62iff1.png?width=2196&format=png&auto=webp&s=7be112a670ae0907ce0aa102cdb1299f822637d9
r/Tudor • Does anyone here wear your Tudor and a fitness tracker on the other arm? ->I believe this is the 4.0
r/Tudor • Does anyone here wear your Tudor and a fitness tracker on the other arm? ->I wear a Whoop band day to day and put on my good ol fenix 5x with a hr band when I’m out running
r/trailrunning • what fitness watch you all using? ->I got my MG yesterday and don't have any issues with the band and clasp. It locks into place just fine and rotates smoothly when removing the whoop. I guess they had some QA issues for the initial batch. I went for a treadmill run yesterday and used my Polar H10 to compare HR tracking to the MG. It was pretty much in line with the H10 and while I did get some cadence lock at one point it corrected itself in like 10 seconds, which is better than what I was experiencing with the 4.0. It was only one run though so doesn't prove much...
r/whoop • My HONEST review of the 5 MG. ->Having had my MG for a couple of days and run, cycled and lifted weights with it, I can say confidently that it's ability to measure HR on the wrist during activity is just as bad as the 4.0 was. The 4.0 was excellent with a bicep band and I am desperately awaiting my bicep band for the MG. I do think forcing everyone to buy new bands was cynical by Whoop. It would have been incredibly simple to making it compatible with existing bands. Apple have with their watch for 10 iterations.
r/whoop • My HONEST review of the 5 MG. ->Heart rate zone training. Alarm. Keeping track of my week month. Satisfaction in achieving goals. Not so much changing my actions but reinforcing actions and assisting with training.
r/Watches • [discussion] Those who went Apple Watch to Traditional ->I do the same. Works a treat.
r/Watches • [discussion] Those who went Apple Watch to Traditional ->I was one of the people who, angry about the way Whoop handled the 5.0/MG launch, rage-quit and switched to an apple watch. Even after the "upgrade fee" issue was resolved for users like me who had a long subscription remaining, I was still mad that upgrading would mean I would lose all the bands I had purchased over the years, in exchange for what seemed to me to be just slightly longer battery life. The whole rollout put a bad taste in my mouth, and I decided to throw my whoop in the drawer and instead just use my apple watch. So I went all-in on an apple watch with bevel. And the apple watch is great! I love it. It's fantastic for outdoor activities - runs, biking, etc - and I love being able to go places without my cell phone and still be reachable. Not to mention, because I use(d) natural cycles, I sleep with my apple watch anyway. I used my apple watch heavily all summer, and figured that bevel was pretty close to the same as whoop for strain and recovery insights, so I really wasn't missing much of anything. Well, after a few months my anger died down and I decided that hey, I've pre-paid for my whoop subscription until fall 2026 anyway, I may as well put it back on and make the most of it. So I did. ........You guys. It's gotten better. The UI has improved, the whoop AI coach is significantly improved and the hormonal insights are \*massively\* improved, to the point where I feel like whoop is potentially the best women's health tracker on the market for fitness-focused people (oura has really leaned into women's health, but I think we can all agree that oura can't hold a candle to whoop for fitness). Comparing bevel to whoop, I mean..... look. Bevel is pretty good. As far as apple watch apps go I think it's the best whoop competitor. But it's just not the same at all. Lol. It's not even bevel's fault - the reality is that your apple watch, taking measurements intermittently when not specifically in a workout, is never going to be able to compare with the 24/7 data from the whoop. No matter how good the algorithm is, you're still making connections between dots that are farther apart. And before people comment that "the whoop HR data is unreliable!!", I can tell you that when I work out with my AWU and my whoop on a bicep band, the HR data is within a hair of each other. So, I'm willing to admit when I'm wrong. The apple watch is a fitness \*tracker\* (and phone extension), the whoop is a dedicated fitness & health \*coach\*. That's the difference. Whoop really does provide something special. I'll be here for the foreseeable future, with my 4.0, and my nicer wristband and my bicep band that fit with it. When my subscription is up, maybe I'll upgrade to the 5.0 and buy \*all new bands\* (still raging about this). Or maybe I won't. Either way though, I am satisfied with the value I'm getting from whoop, and no, I don't think the apple watch is the same. Anyway, thanks for coming to my TED Talk.
