Compared side by side
The Amazfit Helio Strap Screenless Fitness and Recovery Band appears in this table next to models from other brands:
Who it's for
Men who want Whoop-style recovery tracking without a yearly fee, and lifters who want a second sensor on the upper arm that broadcasts heart rate to gym machines.
Caveats
- Auto-detected workouts are unreliable: DC Rainmaker logged 10 workouts on a day he did 2, so start sessions manually.
- Sleep onset was off by about 37 minutes on one night in DC Rainmaker's test; Apple, Garmin, Oura and Whoop were closer.
- Daily strain caps at 100%, so a very hard day looks like a moderate one.
- Max heart rate is fixed at 220 minus age, which skews zones for fit men.
- The hook-and-loop strap is one size and may wear over time.
- Training plans only work when paired with an Amazfit watch.
