Devices & Sync

Using Wader on multiple devices and keeping your data in sync.

Wader syncs your logbook to the cloud automatically. You can use the app on multiple devices with the same account and your data will stay in sync.

Using a second device

Download Wader on your second device.
Sign in with the same login method you used on your first device — the same email address, or the same social login (Google, Facebook, or Apple).
Wader will download your flights from the cloud automatically.

Each flight card shows a sync status icon:

Green cloud icon — the flight is synced to the cloud.
Red cloud icon — the flight has pending changes and has not yet synced. An internet connection is required to complete the sync.

If flights you've logged on one device aren't showing up on another, follow these steps:

Make sure both devices are online.
On the device with the newer data: tap the sync button (top-right of the Logbook screen) or pull down to refresh. This forces an upload to the cloud.
On the other device: tap the sync button or pull down to refresh. This forces a download from the cloud.
Allow a few moments for the sync to complete.
If flights still don't appear: update Wader to the latest version (App Store / Google Play). Most sync issues are resolved in recent updates.
If the issue persists after updating: go to More → Database Manager → Reset Database. This deletes local data only and forces a fresh download from the cloud.

Before resetting the database, make sure all flights show a green sync icon. Any flights with a red icon (unsynced) will be lost during a reset.

This usually happens with a large logbook, on slower network connections, or when using an outdated version of the app.

Step 1 — Update Wader to the latest version (App Store / Google Play), then reopen the app and wait for the download to complete.

Step 2 — If the loop continues after updating: go to More → Database Manager → Reset Database to force a fresh download.

This issue is most common after importing a large amount of historical data or switching to a new device for the first time.

If you need to completely reset Wader's local data:

Go to More → Database Manager → Reset Database.
Your cloud data is not affected — it will re-download automatically once the reset is complete.

Any flights with a red sync icon (unsynced local changes) will be lost when you reset the database. Export or sync them before proceeding.
