No hype, no spot-reviews. We explain what actually works in 2026: Health Connect, data export, official OAuths, GDPR, picking the right ecosystem.
Main guides
Colmi R02: the €25 smart ring that finally syncs all your health data

Colmi ring in FitMesh: everything we read today, plus the R09's temperature sensor
With the Colmi R-series (R02-R10) and OEM clones sharing the same BLE protocol, FitMesh Sync already reads steps, distance, calories, heart rate, resting HR, SpO2, HRV, stress, sleep with stages and battery over direct Bluetooth, merged with your smartwatch data with no double counting. The R09 model adds a skin-temperature sensor the R02/R03 don't have: here's everything the ring already does today, and how we use that sensor for one more wellness signal — verified on physical hardware, included in the app's current version.

Where your data actually lives, and why an EU server matters
Before you connect your ring or smartwatch to an app, it's fair to ask where your health data ends up.

How reliable is Colmi R02 ring data, really
