Sync Colmi Ring to your dashboard
FitMesh Sync supports Colmi R02 and R03 smart rings (and OEM clones sharing the same BLE protocol) via direct Bluetooth connection. The app reads the ring without needing the manufacturer's companion app: steps, distance, calories, heart rate (daily log + resting HR), SpO2, HRV, stress, sleep with stages and battery feed directly into your multi-device dashboard. Nightly ring data merges with daytime smartwatch data, no double counting.

Supported data
The data types FitMesh can read from this integration. Green dot = supported, grey = not available from this source.
Technical note
Direct BLE read (no Health Connect, no OEM app). FitMesh connects to the ring as a Bluetooth device, downloads raw data and merges it into the multi-source dashboard (ring+smartwatch fusion: the ring covers nighttime and metrics the smartwatch lacks). Sleep with stages: the ring is the specialist and wins overnight.
Frequently asked questions
Does it work with the Colmi R03 and OEM clones too?+
Yes. FitMesh uses the BLE protocol shared by the Colmi R02, R03 and several OEM rings that run the same firmware. If your ring uses the QRing app or a companion app identical in interface, it's likely compatible.
Do I need to keep the manufacturer's app installed?+
No. FitMesh Sync connects directly to the ring over Bluetooth and downloads data on its own. The manufacturer's companion app is not required and you can uninstall it if you prefer.
How does FitMesh affect the ring's battery life?+
FitMesh downloads data in batches when the ring is nearby, without maintaining a continuous BLE connection. The impact on ring battery life is minimal (the Colmi R02 typically achieves 5–7 days of battery life).
How accurate are the heart rate and SpO₂ readings?+
Colmi R02/R03 rings estimate heart rate and SpO₂ via optical PPG sensors. The data is informational: useful for tracking daily and nightly trends, but not a replacement for certified medical devices. Always consult a healthcare professional for clinical use.
Is my data private?+
Yes. Ring data is read via Bluetooth directly by the phone and sent only to your FitMesh account's Supabase backend (EU servers). It does not pass through the ring manufacturer's servers.
