Scan Pro App for iOS: Do I have to buy a new license for every iOS device I own, e.g. my iPad?
Don't worry – you won't have to buy another license to use on your second device (or even more).
To get access to your Scan Pro App Pro features on an additional device, just to go the App Store, search for Scan Pro App and download the app. Scan Pro App will automatically search for receipts on your account and restore your Scan Pro App Pro Features on your new device.
Please note, that it is not possible to use your iOS purchase for Android devices or vice versa. The conditions in the iTunes App Store and Google Play Store don't allow such cross-app-store-pricing.
