Can you restore a deleted app from iPad Pro

If what you need is the data in that app, there are 2 ways, but one depends on how you deleted the app.

1 - Restore the iPad from a backup you have of a point earlier in time.

2 - If you deleted the app but decided to maintain it's data on the device, you can simply reinstall it and it should open just as you left it. If you removed the app AND the data, the only way is the first one, otherwise it's gone.

If you don't need the data, you can simply reinstall it from the App Store.
