Purrfect Memory
Purrfect Memory is a Mac app to help you learn phrases, facts, Bible verses, or really anything you need to remember. It’s designed to stay out of the way and be unobtrusive. It runs right in the menu bar so it stays out of the way until you need it.
You can download it for $2.99 on the Mac App Store, and you can also add it prebuilt templates through in-app purchase.
