Many apps (not all) have additional documentation available online. You can find links to app support in the App Store:
- Go to the App Store on your iPad and search for whichever app you’d like more info about (even if you already have the app installed on your iPad).
- In the search results, tap the icon of the app you searched for. This will bring up a more detailed page on the app.
- Tap the “App Support” button on the lower left of the screen.
