. Please see all the support topics in this knowledgebase and in the users manual
If you have backed up to the iCloud, iTunes, or Android equivalent, it should be possible to restore the App to the original device or a new device with the same Apple ID. Alternatively, if the app is installed on an older Apple device, back the app up to the iCloud or iTunes and restore it on the new device.
The App can be installed without the Apple store using the Apple .ipa installation file. However, Apple locks all apps, free or not, to a given Apple ID. Hence Apple will not allow an .ipa file to be installed which does not have the users Apple ID associated with it.
Installing the .ipa installation file is possible with a jail-break phone.
Alternatively, there are other solutions which allow the file to be installed such as the Altstore or other like solution
