COROS Heart Rate Monitor
COROS Heart Rate Monitor is an armband from 2023, sitting in the budget band at an indicative $79.
It reads 1 of the 33 signals this comparison tracks. Nothing at all from heart and vitals, sleep, fitness and body composition.
By sensor class: 1 at high accuracy. That grade is my classification of the hardware, not a lab test. Those readings come from an optical heart rate sensor and an accelerometer.
Rated 3ATM. It weighs 19 g. No subscription is required.
Optical upper-arm HR band; live HR over BLE for workouts; DCR: no valid HRV/RR, no sleep.

Turn a supported wearable into daily health scores
MyBodyAI reads COROS, Oura, Polar and Withings by logging in, Fitbit and Pixel Watch through Google Health, and Garmin through the Android app or 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. One developer builds and updates it. If it saved you hours of research, a coffee is a kind way to say thanks.
