Steps & distance
Steps and distance read from Apple Health or Health Connect, or over Bluetooth from a compatible Colmi ring. On Android, background updates depend on your battery settings; to update manually, tap “Sync now” in the app.
Available on Android and iOS
Your fitness data, together.
Even when you switch devices.
FitMesh Sync is an app for iPhone and Android. It reads the data that watches, rings and fitness apps save to Apple Health or Health Connect, with your permission. With a compatible Colmi ring it also connects over Bluetooth. It shows all of it together, day by day.
It works with a single watch too. If you switch phones or use more than one, sign in with the same account and you will see the data already synced, as long as you have a connection and active access. Workouts recorded with the app stay on the phone that recorded them.

How it works
Three steps, on iPhone or Android.
01Step
Install and sign in
Download FitMesh Sync from the App Store or Google Play, then create an account or sign in. If you switch phones or use more than one, use the same account.
02Step
Allow access
On iPhone, give access to Apple Health; on Android, to Health Connect, choosing which data to read. If you have a compatible Colmi ring, turn on Bluetooth and tap “Pair ring” in the app. FitMesh only receives what your sources save and you allow: if a measurement is not shared, it does not arrive.
03Step
Check your data in the app
FitMesh brings the data you allowed together by day. If you use more than one phone with the same account, each one also shows the data the others have already synced. To update whenever you want, tap “Sync now”.

The app
See FitMesh in action
Real screens from the Android app, straight from the phone.
Features
The smartwatch data FitMesh reads, organized by day.
Heart rate
Daily average, min/max range, resting heart rate. Spot trends in your cardiovascular health over time.
Sleep with stages
Total duration, deep, REM, light, awake. Color-coded bar and quality indicator.
Calories & activity
Active and basal calories, elevation, floors climbed. Walks in green, workouts in red.
Several devices, one day
When several sources count steps on the same day, FitMesh shows one step count. By default it builds that count based on how reliable and complete the data is and, with a ring paired over Bluetooth and the phone's health app, it can build it hour by hour. In the app you can also pick the source you prefer for steps. If a number doesn't add up, compare it with the manufacturer's app.
