Great product
This Helio Strap is a great option if you like detailed training data but do not want another full smartwatch screen on your wrist. It tracks 24/7 heart rate, HRV, sleep stages, stress, and 27+ sports modes (including strength and HYROX) with second-by-second data, then turns it into clear recovery and training insights in the Zepp app—without any subscription. The strap is light, water‑resistant to 5 ATM, and gets up to about 10 days of battery life, so you can wear it day and night with very little charging or fuss

A strong (say 4.5 stars) competitor to Whoop
Updated review Jan 2026 – FYI battery life is excellent, usually 6-7 days before charging and best news is that it looks like the algorithm is self learning which is great. I can now wear on my wrist, it recognized workouts (identified as “activities”) and is as accurate as my Garmin 55. Performance is now very similar if not equal to Whoop and Garmin. The App could use some updates but otherwise definitely a strong alternative to Whoop.Updated review – now 4 stars. Moving Helio Strap to bicep made a total difference. Would be a 4.5 if it worked for me on wrist.Original reviewHave been a Whooper for past 1.5 years, and based on reviews wanted to try Helio Strap. Have been wearing Whoop and Helio strap on same wrist for past 3 weeks and here are my observations. I also use a Garmin watch for training and Whoop and Garmin show very similar results from exercise.Pros:Battery Life – excellent, 8-10 days so far.Product Support – excellent – I contacted them twice by email and received responses within 24 hoursFit/Comfort – excellentChoice of alternative bands – excellent (many choices available on Amazon), picked up 4 for $10 versus the $20-50 choices for Whoop. A non-Whoop band fit but did not work for exercise or fast motion.Subscription – Excellent, as there is none!!Sleep Mode Detection – Excellent and very similar to Whoop results.App – Good, not as well laid out as Whoop and hopefully will continue to improve.Battery Charger – Good, except that the Helio Strap site does not indicate that the T-Rex chargers (2 for $10) will work. Whoop extra/replacement battery is $49.Cons:Activity/Exercise – Not good for multiple exercises chosen. I have tried manually starting activity (outdoor running) and tried non-GPS mode or switching it to treadmill. I did not measure the full workout. On advice of customer care, switched detection level to high, and it did detect running but did not end it when I finished. The calculations it made for the zones of heartrate were not correct and way off (too low). This is the one area that I hope company focuses on as Whoop definitely works flawlessly here. I will try GPS mode and also moving monitor to my upper arm and report back.Heartrate – accurate and same as Whoop. However calculations of heart zones during exercise way off (too low)Overall I still believe this is very good value for the money and will continue to use. I do hope they can address/improve the algorithms for exercise/activities.

Ten star greatness
I purchased this as a sleep tracker only (when my fit-t died after less than a year and the company got acquired by the data-mining king). Then I realized I could use this instead of the Pol-r chest heart rate strap I was planning to get for my rowing machine, and that arm/wrist placement is way more convenient. Then I realized the app keeps improving and tracks a bunch of stuff including my workouts. I compared it to my friend’s $pple device after a long hike and the stats were almost identical. Even food logging is so simple, you can speak your foods and it calculates calories and protein content fairly quickly and accurately, plus you can edit entries. Then I got into an argument with my sister and the thing started vibrating violently on my wrist (I didn’t even know it could vibrate) and I realized it was warning me my stress level was too high! So this thing is ending up to be FANTASTIC and way more useful than I thought. The only negative so far is that the strap it comes with is too large for me (I have tiny wrists and arms and could use it as a bicep band except it is non-stretchy so uncomfortable there), BUT it uses regular style watch bands (22mm) so that is another plus! Get whatever band you want. I love that this device is comfortable, lightweight, has good battery life and allows me to wear a regular watch (you know, the kind with an always on display that doesn’t need nightly charging). With the added security of not tracking and selling data without my permission, no subscription and an affordable price i think this is a NEAR PERFECT fitness and bio tracker. (Please, Amazfit, don’t let a bigger company buy or influence you and ruin this good thing you have going).

Excellent tracker for a great price.
I’ve begun my fitness journey and I was looking for a device that was screen less and not intrusive. I have an Apple Watch that I wear daily but this tracker is just different. It works great and the food tracker is perfect. If you snap a photo of the label, it will automatically calculate the information.The Zepp app is the best part of the tracker. It’s reliable, accurate and the data is easy to understand. I get about 5-6 days on a charge which is much better than my watch and it lets me know when it needs to charge. I bought a couple of extra adapters to keep with me and at work so if I need to top it off, I can.This also has an alarm feature which I really like. I use it as a secondary wake up alarm and to turn it off, all you have to do is tap the tracker a few times and then it’s off. For the price and features, you really can’t beat this.

This replaces a FitBit. Things I love about this: Battery life is at least 10+ days as promised. It has heart rate broadcasting via bluetooth so I can get onto my bicycle with a head unit, and it’s good to go. It will push resting heart rate, sleep, and steps to Intervals dot ICU which is great alternative to the Garmin universe. On the downside, I found it too irritating on my wrist – the circular disc protrudes too much. I don’t have faith the hook-and-loop fastener will last too long either, I prefer an elastic style instead. So, I purchased a third party elastic style band and wear it on the upper part of my lower arm. This position may be affecting my sleep tracking as it seems less likely to pick up on times I’m actually awake – sometimes not even catching when I get up at night to use the toilet. Apart from awake time, it generally aligns with the Fitbit sleep tracking.

Simplemente murió. Después de 1 mes dejó de cargar y murió. Busqué a Amazfit México directamente y como la compré en Amazon sencillamente no me ayudaron. Regrese a WHOOP

Amazing! Works without subscription, unlike Whoop. Same or better quality and features than whoop.

Been looking for such a device for a long time. Could never stomach the subscription model – so this is refreshing. After the first few weeks, the Helio appears very accurate, and the data is super insightful. I have already changed some daily habits as a result, and I pay more attention to the bio charge. Nice to see the Polar land a new device also. These devices are only going to get better. Looking forward to the arm band being available in Australia soon.
