# Data Updates, Offline Use and App Updates

Tap the NOTAMbriefing.com logo at the top left of the map, or press `D`, to open the menu with the data status and the app's own options.

## How fresh is the data?

The data is updated around the clock. New data is published every 10 minutes, and the app downloads it by itself, also when you reopen it.

The menu opens with a short checklist. The first line says whether your data is up to date, with the time of the data and how old it is. If new data is late or cannot be fetched, that line turns amber or red and says so. **Check** looks for new data straight away. The other lines show whether you have Live or Essential data, where the data comes from, and whether the app is the latest version.

Data comes from official sources: NOTAMs from the EUROCONTROL European AIS Database (EAD), and airspace use plans (AUP/UUP) from the EUROCONTROL Network Manager.

## Offline use

The app keeps the map and aviation data you have loaded on your device. When your connection drops, a notice says **Offline** and the app keeps working with that data.

While offline, new map areas, searches, account checks and data updates may not work. They come back when you are online again.

## App updates

When a new version is ready, a banner says **Update ready**. Tap **Update now**, or the update installs the next time you open the app. The menu's app line also says **Update ready**, with an **Update app** button. **Release notes** in the banner and in the menu show what changed.

## Install the app

Tap **Install app** in the menu to add NOTAMbriefing.com to your home screen or desktop. On an iPhone or iPad, the app shows the steps for Safari's **Add to Home Screen**.

## Docs and release notes

The menu also has **Take the tour**, a short tour of the map and of what Live adds, **Release notes**, **Docs**, which opens this documentation, and **Feedback**, which opens an email to the team.

## Something not working?

Open **Help and troubleshooting** at the bottom of the menu. **Reload map tiles** reloads the map tiles, and **Reset everything** clears the app on this device after asking you first. **Contact us** opens an email to the team with the details support needs already filled in. You can also [ask the team](/docs/ask-the-team).
