Japan has this thing they do where they sell green/red highlighters with transparent green/red slides; you highlight words, terms, and formulas you want to memorize on a piece of paper, then slide the transparent colored slides over them to essentially cover them up as you're reviewing. This app attempts to replicate that. It's not as good as using flash cards (because you can't scramble the questions you ask yourself as well), but the HUGE advantage it has over making your own flashcards is this method takes a LOT less time to make your self-testing materials (which is important if you have a HUGE list of things you need to remember, like in med school).There aren't many apps that are like this, and this is one of the few ones that actually does do it in english. It does a good job, but there are some things I would like to see in it in the future:1) have the ability to write/draw/type notes on each paper, and make it so that it reveals itself when you click on the word/term you want the drawings to help you with (which can help give yourself hints as to how to remember each item)2) have the ability to upload/update/download to a cloud site, like google drive, dropbox, or icloud3) release the app on mac/windows/android as well, and allow files to be sent/updated to others, regardless of what operating system is used

The only feature missing, that would make this app perfect, is the ability to write notes with Apple Pencil on imported images/docs. Please add.

I use the app everyday for Medical school. It is easy to use and better than Image Occlusion 2.0 for Anki. However, the program could be better if you can add text in pages, and be able to copy a page for reuse.***I gave 3 stars because one big issue i found so far. When I import a pdf made from powerpoint, i have to rotate every single page 90 degree. Please fix

This is an innovative and functional application. If the Leitner system is added for review, it will be great.Auto-back up with ios account can also be very useful.
