I tried a subscription-free Whoop alternative — and it ticks all the right boxes

The amazfit helio strap fitness tracker with a screenless design, showing the gray strap worn around the wrist and the charger.

Many of the best fitness trackers are expensive. Some premium watches go up to $800 and beyond. But not Amazfit, and that’s one of the reasons why I adore Amazfit’s fitness trackers so much.

When Amazfit announced the Helio Strap earlier this year (2025), I was super excited to test it out. I’ve been using it for the past three weeks (I’m even wearing it as I write this), and I’m so impressed.
