Connecting a device

Will I lose my data if I change phone or watch?

  1. Install YuMuuv on the new phone and tap Login. Don’t sign up again, as that creates a second account.
  2. Tap your profile circle (top right) → Your details → Change integration and connect your watch or health app again. Allow all the permissions.
  3. Tap Update your data.

If you switch to another watch brand, or make a new account in your watch’s app, connect that one under Change integration. If both the old and new phone still send steps, remove the old phone as a step source so steps aren’t counted twice.

Days missing around the switch can be fixed: How do I correct wrong steps?
