Whoop 4.0 In-Depth Review // Accuracy and the Algorithm

Phenomenal review, I very much appreciate your experimental approach and data analysis review. Subbed!

Appreciate the bicep band section, I’ve been underwhelmed with the accuracy of my whoop on the wrist and was looking for reviews of the bicep band accuracy to see if it would help

You might as well sell asteroid insurance. Just because Joe Rogan uses this doesn’t mean you can charge 200$ a year. Don’t give us the highs and lows of a product that has great features but is pulling money from the pockets of people that want to be better that can be better with out that meaningless information it gives. The cost of living is far enough let’s not rob the public more than we need to. If a pro athlete wants this that’s fair but let’s not sell this as something that the public needs to be healthy.

The whoop needs gps I'd rather not bring my phone or have to wear another tracker for gps.

Great review - I fully agree with everything you have said. For me, Whoop is worth it because of the gamification of wellness/fitness in which I can compete with my friends. I look forward to seeing my recovery every morning but I know it has its flaws (hardware, price). What wearable do you personally use and believe in now - Garmin? I am very open to trying new wearables. Thank you!

DO NOT GET THE WHOOP BAND, i tried the free trial 6 months ago and now that im looking into a non subscription watch, i see that i committed to a 12 month membership and ill end up having to pay $360 for one year using this shitty tracker. if you want to try it just do the annual and pay upfront bc you’ll save $120. its not worth it at all, an apple watch does everything and more for less money.

Geez. This guys works out a looooot.

Thanks a lot for taking the time to make this review, you put a lot of effort into it and it really shows! I did have one question about the subscription I'm not sure if you know, what happens if you subscribe for one month and don't like the watch. Can you just cancel and keep the device? Or do you need to send it back? Thanks!

Love the data and the comparisons! Wish there were more technical unbiased reviews on YT.
Heart felt gratitude DesFit!

It was cool in 2020, but in 2024 pretty much all watches have HRV, training readiness and sleep coach or sleep tracking, so you'll know if your body is recovered and ready for a workout.

Very good review, too bad subscription is required. And a very high price on top of that.

Nobody talks about privacy and data protection

just want to point out that we shouldnt give kudos for support doing their job while the company falsely advertises the battery life..

Thank you for your detailed and honest review!!!!

Really fancy one but wouldn't pay a subscription.

Very helpful! Huge turn off that it drops out of HR tracking periodically.. my Apple Watch is doing the same thing, (se gen2) so I’m on the market…

Also I see the strain / recovery model on Strava as well, and I can’t decide if I like it or not.. maybe because it seems so hard to improve the “effort”score.

The best review about Whoop I've ever watched.

Can i view the information on an Apple Watch?

Thanks!

Nothing more than another pathetic subscription based product

Do not, I repeat DO NOT get Whoop. It’s a scam. There is no monthly plan, you get locked into a full year after the 30 day trial. And it takes 30 days to calibrate, so having it for less than that doesn’t give you accurate stats. Imagine that, it’s clearly a way to get you stuck into a subscription. There are a couple Facebook groups and multiple people had no idea you couldn’t cancel after the 30 days. Also, it doesn’t even track sleep accurately. I had to keep editing it every day. And the customer service is the worst I’ve ever seen. Trust me, don’t waste your money.

It actually DOES have GPS within your specific workouts…. JS -😂a lifetime customer

You also use a garmin watch... why´s that? I have a fenix 7 now.... but this whoop looks more accurate on HR , HVR measure? Would be nice to have some review about those difference! Nice video though! Cheers

Do not buy this product it's a scam

whoop is a gimmic. nonsense information and on top of that an expensive paid subscription

Great video! In regard to the battery pack charging issue… could it be that it stops at 99% intentionally to prevent you from overcharging the battery pack? Just a thought.

Part of my minimalistic life is not to have another subscription 😂. It’s great tech though.

your heart rate is high my guy

YUP not fun of having to subscribe, specialy at that cost, the subscription trend is getting kind of out of hand.

I saw it with one of those famous soccer players, he uses it to check his training level and recovering time and others as well.
What I want to know is, if there is a sport watch that can perform the same as whoop

Very simply, this is for people who train every single day or even more than once a day. If you don’t train every day, the thing is unnecessary. Oh, and on the sleep coaching? Don’t drink caffeine after 3 PM and don’t do screen time in bed. You’re welcome.

Do you have any comparison data for a whoop to an Apple Watch.

What watch wouod you suggest to those with disabilities wanting to Track Health, sleep And Health during Fitness.

Samsung Galaxy watch 6, or The whoop,
I really hope Someone replies to This im having a hard time figuring out the best one for my needs

Hi Des .. I noticed that you use a bicep band.

Recently I had a warm/hotish (little uncomfortable under the arm above ribcage) device after I removed the battery pack from charging it.

The battery was charged properly and only in place for enough time to charge it full and on removal it was noticeably hot that disappeared to warm quickly enough after that.

I’ve reported it to Whoop a week today and they said they would send a replacement battery and device but the tracking link doesn’t work and the replacement didn’t arrive.

As you know data collection is the purpose of the device and removal or absence breaks the chain and isn’t ideal after three years of use.

Is this a problem that you have come accross ?

Obviously under the arm is warmer than the wrist and is more likely to be covered up except perhaps in sleep.

For me I would have thought such an occurrence would be flagged as a priority by Whoop but looks like it’s same as any other issue.

I’m a big fan of Whoop and I really wonder is non wrist band or clothing use a bit of a temporary location solution where you have to move it back to the wrist.

Just an interesting development that I think I need independent information on as I posed these questions to Whoop without reply.

I’m based in Ireland and all sort is by email online with a ticket number and wait for reply type support.

Keep up the good work and thanks in advance for any feedback.

no thx ..like you said for that money i can but very good fitness watch..i will never commit to anything like that..thats why i skipped Oura ring to..i am sure at some point some company will do the same as Whoop for free when we only need to pay for the device :) thank you for another great review :)

Great review, I intend to use Whoop solely for the sleep, HRV, and recovery data...don't like sleeping with a heavy watch. I use a Garmin forerunner 945 as well as a garmin HRM Pro Plus chest heart rate strap for key workouts. I mainly use during running threshold workouts to stay in the proper range. Your going to get the most accuracy from a chest heart rate strap.

This was such an impressive comprehensive review. Thank you for doing this! Very helpful

Any plans to compare the accuracy of the data gathered by Oura vs Whoop and Garmin products?

I was on board until the price point. Ouch. Looking for something to track BJJ training and weight training but not at that price point. Dang!

Is the 21 not for the borg scale

Would be curious what you think of a concept that does something similar, but for the brain / mind - strain, recovery rest.

Great video.

Des, I love your reviews but I completely disagree with when you say "not too bad at all".

The whole marketing campaign is based on data. If their data is statistically insignificant, which it is, then it's a pointless product imo.

Charts are pretty look at, but when heart rates are being measured 10-20% lower consistently (e.g., in weight lifting workouts), it's worrisome.

It's clear that there is a design fault due to the inability to adjust to quick heart rate jumps, which then further devalues their whole concept of giving HRV a high score in their algo. HRV is literally dependent on being able to track quick changes in your heart rate, which the product can't do well. All over all -- I think the product has potential and has pretty charts-- but the charts and algo are meaningless when studying them from a scientific point of view.

my device did not work. I want to warn everyone I can that whoop company cheats its customers. Despite warning that you can return the device it is a big scam. Although I am within 30 days to return it, they do not answer my messages, it is impossible to contact them and if they answer you, they are copy-paste messages without providing you with the steps to return the device. I will try to warn as many people as possible of this scam. Be careful! it's really frustrating and sad to see you are being scammed

I'm sorry but Whoop is a rip off

I care mostly about heart rate and sleep tracking, and i like the low profile hardware of the whoop. I dont really need all of the other features that smart watches provide, but i also dont need the strain score and other crap thats in the whoop app. If i could just buy the damn whoop for 250 and be done with it i would but im not ibterested in paying for their 2 year subscription for data i wont care about

What people should understand about Whoop is that you're not really paying for the device. You're paying for a platform and lifetime access to constantly developing technology and insights in the health monitoring space. If that's what you're interested in, then this is the top of the line, and you have to pay a premium price.

I bought it when my fitbit sense died and there's no real repair support for their flagship devices. Whoop's support for the hw is included in the sub so I am using a whoop for fitness/sleep and a smartwatch for smart watch stuff which I take off when I go maniac mode. I'd like to hear about those who have broken a screen on the garmin and what that repair process looks like.

Dang. Subscription nonsense.
