What Syncs
OMN4 sync keeps supported personal data in step when each device uses the same account.
What Syncs
When sync is working normally, OMN4 can sync:
- routes, tracklogs, waypoints, and folders
- all current built-in Activity preference rows, including favourites, calculations, independent Route/Track/Waypoint appearance, and configured destinations
- the account Default Activity
- the folder/item hierarchy
- each Route, Track, or Waypoint's Activity and custom appearance values, including explicit No symbol
- GPS marker size, thickness, colours, and direction-line appearance
- mobile Stats Bar visibility, one-row or two-row layout, and the item chosen for each position
- Recording Tracklog Colour
- other supported settings, including units and coordinate display
- supported icon imports
Each item's custom-versus-Activity source state is synced, not just the current rendered appearance.
The Stats Bar is displayed and edited only on mobile. Its layout still travels with your account when you use OMN4 on desktop, so it is ready on your other signed-in mobile devices.
If the same synced setting was changed on more than one device, the most recent edit becomes the account value. The device that happens to sync first does not get priority. If two edits have exactly the same time, OMN4 keeps the value already in the account.
What Stays On One Device
These items are managed separately on each device:
- downloaded offline maps
- temporary caches
- platform permissions such as location access
- theme and screen orientation
- the current map position and selected map
- live GPS and tracklog-recording state
- mobile data, printing, Points Explorer layout, and search state
Your account controls map access and subscriptions, but each device manages its own map downloads, storage, updates, and verification.
If a route appears on a new phone but the map underneath it does not, that is normally a map-download task rather than a sync failure.
Styles And Current App Versions
The current styles system requires a current OMN4 app and a complete refresh of Routes, Tracks & Waypoints before normal uploads begin on a new or rebuilt installation. This is different from Sync now checking for ordinary changes.
Retired app versions cannot sync current Routes, Tracks & Waypoints data. Update every supported device. A pre-v3 beta installation must be removed before installing the current app; see Styles Update and Full Refresh before removing it.
Anything left only on an offline retired installation was never in the synced account data and cannot be transferred automatically. Contact support before removing the old installation if you believe it contains the only copy of important data.
Moving data between OMN2/3 and OMN4 is a separate bridge workflow. See Moving from OMN2/3.
