Suunto Run 2
Suunto Run 2 is a watch from 2026, sitting in the mid-range band at an indicative $349.
It reads 11 of the 33 signals this comparison tracks. Nothing at all from body composition.
Those readings come from an optical heart rate sensor, an optical blood oxygen sensor, a GPS receiver, a barometer and an accelerometer. Blood oxygen is measured during sleep, not continuously through the day.
Its 10 days per charge are the 61st longest of the 80 devices of its kind here that publish a figure. The AMOLED screen can stay always on. Multi-band GPS. Rated 50m / 5ATM, fine for swimming. It weighs 35 g. On top of the tracking it also handles music on the device and offline maps. No subscription is required.
September 2026 successor to Suunto Run: a three times brighter screen, a new 12-channel heart rate sensor, 24 hours of dual-band GPS and free offline maps, in a 35 g body.

Not established: Sleep stages, Sleep score. The maker does not state it and no independent test I trust settles it. The signal counts on this page only include confirmed signals, so it is left out of them, which is not the same as the device lacking it.

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.
