# Devices & 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

1. Download Wader on your second device.
2. 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).
3. Wader will download your flights from the cloud automatically.

***

## Cloud sync status

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.

***

## Flights not appearing on a second device

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

1. Make sure **both devices are online**.
2. 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.
3. On the **other device**: tap the sync button or pull down to refresh. This forces a download from the cloud.
4. Allow a few moments for the sync to complete.
5. If flights still don't appear: **update Wader to the latest version** (App Store / Google Play). Most sync issues are resolved in recent updates.
6. 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.

{% hint style="warning" %}
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.
{% endhint %}

***

## "Downloading Flights" message keeps looping

This usually happens with a large logbook, on slower network connections, or when using an outdated version of the app.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

{% hint style="info" %}
This issue is most common after importing a large amount of historical data or switching to a new device for the first time.
{% endhint %}

***

## Clearing app data from your device (full reset)

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

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

{% hint style="warning" %}
Any flights with a **red sync icon** (unsynced local changes) will be lost when you reset the database. Export or sync them before proceeding.
{% endhint %}
