How to switch smartwatch without losing your data history

You just ordered a new watch, or you are moving from a watch to a ring. The question that often stalls the purchase is always the same: what about all the history I have built up over the years? Steps, sleep, heart rate, workouts, months or years of data living inside the old device's app. Changing brand usually means starting over from an empty chart. Be careful not to mix up two different cases: this is not about going from Android to iPhone (that is an operating-system change, covered in From Android to iPhone: how not to lose your fitness data). This is about changing the brand or model of the wearable itself: you stay on the same phone, but your Garmin watch becomes a Galaxy Watch, or your Fitbit becomes a Colmi ring. Let's look at why the history breaks and how to keep it whole.

Why changing brand breaks your history

Every manufacturer keeps your data inside its own app and its own servers. Garmin in its ecosystem, Fitbit in its own, Samsung in its own, Xiaomi and Amazfit in their respective companion apps. They are silos: designed to work well as long as you stay within the same brand, not to let you walk out with your whole history in hand. When you buy a device from another brand, the new app starts from scratch. The old history does not transfer: it stays frozen in the previous app, the one you will slowly stop opening. Neither app shows you the continuous line of your story, before and after the switch.

• •Your steps and calories history splits into two separate charts, one per app.
• •Sleep with its stages (light, deep, REM) restarts from zero in the new app.
• •Resting heart rate and HRV trends lose their point of comparison with the previous months.
• •Workouts recorded with the old device stay in the old app, not the new one.
• •If you switch brands again later, the problem repeats and you now have three places to check.

Continuity lives in the cloud, not in the device

FitMesh flips the logic: instead of tying your history to a device, it keeps it on your account, in the EU cloud. The watch or ring is only the source of the moment's data; if you change hardware tomorrow, the source changes but the history stays the same, on the same account. FitMesh Sync reads the health data from your wearables and shows it in a unified web panel, deduplicated: the same step is not counted twice, even if you run two devices in parallel for a few days. You can view everything from any browser, as we explain in See your wearable data from a PC browser, and if you wear several devices at once the dashboard merges them without counting the data twice.

Checklist: before, during and after the switch

1. Before: install FitMesh Sync on Android while you are still using the old device and connect it, so your recent history enters your account right away.
2. Before: check that the old watch writes to Health Connect and let it sync for a few days, to pull in the historical baseline.
3. During: once the new wearable arrives, connect it to its companion app (or, for the Colmi ring, directly to FitMesh over Bluetooth) and grant the Health Connect permissions.
4. During: keep both devices active for a few days if you want a soft transition; deduplication prevents double counting.
5. After: open the web dashboard and check that the line of steps, sleep and heart rate continues with no gaps across the switch date.
6. After: once you are confident, you can stop wearing the old device; the history stays in your account anyway, independent of the hardware.
