    Excellent Fitness tracker

    I've been wearing this now for two and a half to three weeks and I am rather happy with it! The track in my heart has been excellent, prior to this I was wearing another Fitness device for about 5 years when exercising and results have been consistent. I've also loved the fact that it does a great job Tracking my sleep as this was a metric I did not have previously period It provides me a score And It's doing this For no additional monthly fee which other fitness devices have. I've watched the number YouTube comparison videos prior to purchasing this for $99 and they have all stated this thing holds up to the woop with the exception a few features on the app. The difference is there's no monthly fee, which that particular device has a large fee associated with it. I have chose to purchase an additional band to go around my bicep and I would encourage people to do this as the band that comes with it will only Fit around one's wrist. Overall very happy with this, I would encourage people to check out a YouTube video for a more in-depth review, but I'm very satisfied with my purchase and would recommend this product to anyone looking for a good Fitness tracker that you wear all the time. Lastly I found the battery is very good I get a solid 9 days out of the device without a charge and again really happy with this purchase

    Budget friendly fitness tracker, no subscription

    The Amazfit Helio Strap is ideally what I’ve been looking for. I can wear this all day and night and have it track my steps, sleep, and movements. I prefer a fitness band like this one because I don’t want the screentime and glow on my wrist any longer. This simply looks like a bracelet but is collecting vital data the whole time. Having a bracelet style design allows me to wear my other dress watch on my opposite wrist and it doesn’t look awkward like I’m wearing 2 watches. First off, I was thankful that this fitness band operates without any type of a subscription service. I am not a fan of subscriptions for just about every piece of tech that I own now. This Amazfit Helio lets me get my sleep, rest, workouts, heartrate, recovery, and so much more all within one app. The Zepp app is required to pair this fitness band and that’s what is used to visualize all your collected data and statistics. I am an avid runner and workout daily. The Helio Strap feels comfortable on my wrist for my hour long runs, and it stays in place for the full duration. The Helio tracks all my important input just like any other fitness band would, but I prefer not having a distracting screen and the Helio works well for that. I get extremely sweaty on these outdoor runs, and the Helio Strap is water resistant and keeps on working very well under wet conditions. Bluetooth connectivity with my iPhone is seamless and continues to stay always paired. The battery life is impressive and can operate for up to 10 days before it needs another recharge, so this for me is a big plus. I really like the budget friendly price, as it’s a one-time cost without continuing to pour money into subscriptions. For some added flexibility the strap can be adjusted to wear on the wrist or the upper arm if you have a certain preference. This is a great addition to your leisure lifestyle or a competitive athletes schedule. The device can help you keep an eye on your training and your recovery to keep you at your peak physical schedule. The watch does all the work in the background, and you can then simply review all your stats within the app. Seamless, easy to use, great design, and comfortable.

Questions & Answers

  • How accurate are the steps, and does it monitor heart health?

    Hi Denny, the Helio Strap tracks your steps throughout the day, along with continuous heart-rate monitoring. For the best accuracy, it’s important to wear the strap correctly and securely. It also monitors several heart-health-related metrics, including heart rate, heart-rate variability (HRV), blood oxygen (SpO₂), stress, and heart-rate recovery. However, the Helio Strap is not a medical device and is not intended to diagnose or monitor medical conditions. Michael | Amazfit Support
