    • 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 ... show more

    • Solid for replacing Fitbit. Easy-to-lose charger.
I got this because I needed to ditch Fitbit before being forced to use a Google account with it. I've used a Fitbit for at least 5 years. Not for intentional exercise or smartphone features, but steps, heart rate and sleep tracking. Everything I was tracking with Fitbit lines up with the Amazfit strap. My heart rate is basically the same, steps and sleep tracking seems pretty good -- at least catching me awake vs asleep. On the sleep tracking part, this differs quite a bit from Fitbits in that Fitbit adds naps to your sleep for the day whereas Amazfit does not. Naps do increase your Biocharge, which seems to represent your energy levels throughout the day. Amazfit seems to catch naps quite well, though possibly a bit oversensitive. For example, if I put myself into a relaxed state and don't move, Amazfit may record that as a nap even if I may not be sleeping. I think the mobile app is solid, though I had a hard time getting it installed on my tablet -- said there was a compatibility issue (maybe it wasn't supported) and I had to use the apk to get the app. Like with Fitbit, you can install the app on a phone or tablet that you leave at home and it'll sync up your heart rate and steps when you get back to it hours or even days later. I don't know whether sleep data is stored long term yet (overnight) as I haven't tried it. The thing I most dislike about the Amazfit strap is the charger. It's about a 1"x1" by maybe 1/4" square unit. Easy to lose. I lost mine today. It's small and doesn't stick out. If you don't leave it attached to a USB cable, you can easily lose track of it. If you get one of these, you may want to consider getting an extra charger or two so you don't have a dead battery waiting for a replacement to arrive. ... show more

    • 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). ... show more

    • 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. ... show more
