# Install and open

AvComp can be opened in a browser or installed as a Progressive Web App after the first online visit.

## <mark style="color:$warning;">Open in the browser</mark>

1. Open the AvComp URL in your browser.
2. Wait for the app to load fully.
3. Choose your airline profile on first launch if prompted.
4. Open the tool you need from the Home screen.

## <mark style="color:$warning;">Install on iPhone or iPad</mark>

1. Open AvComp in Safari.
2. Tap the Share button.
3. Tap **Add to Home Screen**.
4. Confirm the name and tap **Add**.
5. Open AvComp from the Home Screen icon.

The first visit must be online. After that, AvComp can load from its local app cache, subject to browser and device storage behavior.

## <mark style="color:$warning;">Updating</mark>

When a new version is available, AvComp show an update banner or lock screen depending on the release. Follow the on-screen update prompt and reload the app when requested.

## <mark style="color:$warning;">Browser notes</mark>

* iOS installation should be done from Safari.
* Offline behavior depends on the service worker cache created after the first successful online load.
* Live weather requires a network connection.
* If the app looks stale after an update, close and reopen it. On iOS, removing and re-adding the Home Screen icon may be needed for icon-only changes.
