Amazfit Helio Strap Pro
Amazfit Helio Strap Pro is an armband from 2026, sitting in the mid-range band at an indicative $199.
It reads 16 of the 33 signals this comparison tracks. Nothing at all from body composition.
By sensor class: 10 at consumer grade. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a skin temperature sensor and an accelerometer. Blood oxygen is a spot reading you take yourself, not a continuous one.
Its 11 days per charge are the 3rd longest of the 11 devices of its kind here that publish a figure. Rated 5ATM / 50m, fine for swimming. It weighs 11 g. Dimensions 11.4 g wrist core plus 10.7 g waist pod. No subscription is required.
June 2026 screen-free strap, sold with an extra waist pod. Same measured signals as the Helio Strap; the waist pod does not measure heart rate.

Turn a supported wearable into daily health scores
MyBodyAI reads Fitbit, Oura, Polar and Withings by logging in, and Garmin from a data export, then builds daily recovery, sleep, load and immune scores, a biological age estimate, and early warnings. Optional, and separate from this comparison.
This comparison is free and ad-free. We build and update it ourselves. If it saved you hours of research, a coffee is a kind way to say thanks.
