Amazfit Helio Strap Fitness Tracker Wristband, 24/7 Activity & Sleep Tracker with Heart Rate, 10 Days Battery, 27 Sports Modes, Strength Training, Hyrox Race, Subscription Free for Android & iPhone

A shocker is what I would call the Helio band from Amazfit. I was a Whoop devotee since 2020. The new device came out and I paid for it, but it was delayed. So I decided to try Amazfit. Here is the comparison: Amazfit has MORE battery life; Amazfit has MORE metrics (biocharge); Amazfit's HRV is MORE accurate; Amazfit works perfectly on the ankle if you want to wear it there, though it is a good looking device on the wrist; Amazfit's sleep tracking is WAY MORE accurate (it isn't even close); and Amazfit has no monthly subscription fee. I wear Oura ring and a Huawei GT 5 watch. The Amazfit belongs in my collection and is a real star of a device. I recommend it highly.

My girlfriend and I each bought one. So far, they seem really useful and accurate enough to help with our health needs. The Zepp app has been really useful and provides the information we're looking for. Battery life had been excellent. Waiting for more "native" and colorful replacement bands to come out. I realize that watch bands work, but I like the idea of bands that cover the sensor, just like the stock band. I would recommend this to other people. I may even try one of the watches in the future.

I'm impressed by the helio strap. If you watch reviews on YouTube you'll find that the heart rate tracking is as accurate or better than Apple watches (really accurate). But the real strength of this health monitor is the zepp app. After a few days of use I found the sleep tracking and activity tracking to be great. After a week of tracking the app had enough data to start giving me training scores (over, under training) so stay patient with that. The auto activity tracking is good too giving me an exertion level during the day based upon heart rate tracking data, which is really what matters. Your daily exertion should be based on heart rate not whether you actually walked 1 mile. There is also an Ai assisted diet tracking feature to measure caloric intake. I even found it tracks naps I take and then records that as input to your daily biocharge reading that tells you how rested you are. Pretty cool. I found myself having to take 2 or 3 days to learn all the features but after a week I'm a pro. Oh, it can also automatically upload auto tracked activity to different tools such as Strava , Google fit, komoot and more. I don't think it uploads to Apple fit. Overall I'm pretty pleased with a device that helps me track my health in such a non obtrusive way.

It’s an extremely good, helpful product for health and fitness enthusiasts. The depth and detail of information and metrics that the band provides is nothing short of amazing.Step counting, heart rate tracking, sleep tracking, calculation of of sleep apnea risk, skin temperature, HRV, exertion level, PAI calculation, a calculation of biocharge (overall recovery and energy for the day), calorie burn and intake monitoring, stress levels, blood oxygen, and a large variety of workout monitoring. Is it a "Whoop Killer"? Mmm.. not really. But at its price, for what it provides, it’s worth every penny, and it’s a strong competitor. If there is any negative, it does take a bit for its calculation on active calorie burn to calculate correctly, and its automatic workout tracking is… problematic. Turn it off. It has an enormous battery life off just one charge and its overall functionality is extremely deep. If you’re a health and fitness buff, I guarantee that you’ve spent more money on far, far worse products than this. The Helio strap is the real deal.

Fantastic Watch – Totally Worth It!This watch is absolutely beautiful and worth every penny. It's lightweight, comfortable to wear, and the app is excellent—though it's worth noting that some features may not be available in all countries.Amazfit's customer support truly impressed me. I reached out with a query and received a helpful response within just 5 minutes. Exceptional service!I definitely recommend this watch to anyone considering it.One small suggestion: I’d love to see more colored strap options directly from Amazfit. Currently, you only get the default strap included, or you’ll need to find compatible 22mm straps from third-party sellers.Overall, I'm super happy with my purchase!Stay fit with Amazefit!

Great tracker, great app but not the strap if you use it for swimming. Used it for 3 days for 2 hour pool swimming each day. The strap became too loose to stay on the wrist. I can't find the replacement strap either. Very disappointed since otherwise it would be a great, low cost alternative for Whoop.

Great value since no ongoing subscription fees. Extremely light weight.Awesome battery charge life of more than a week per charge .Tracks steps, sleep, heart rate and workouts very well. Loving it!
