You will want to upgrade. – Memories - Instant Photo Scanner for Throwback Thursday Review

I emailed the maker of this app, and this is the answer I got to the question "Why would I want to pay $1.99?" Answer- " You need the upgrade only to export or share photos without watermark." Information not in the app description. Not happy this is not out front for people looking to get the app, so I'll put it in my review.
