When does the free Photo Scanner app require an upgrade?
For this reason, some app features are limited, and will become locked after several uses. To unlock more features and remove all restrictions you will need to upgrade to a Photomyne account. Here are the details on what the free app offers vs. having an account:
Upgrade options: When reaching the given limit in the free app, you'll see the pop-up notice (shown below).
Having an account is practically a MUST if you have lots of paper photos you'd like to scan, save, and share. To join Photomyne, simply tap the side-menu and select Upgrade.
Please note that a Photomyne account is an in-app purchase of an auto-renewal subscription. You can cancel it at any time via your iTunes / Google Play account.
