Create your own notes of anything you'd like to learn - or just clone someone elses.
Swipe through your notes. It's super-easy: left when you know it, right when you need some help.
Revisy keeps track of how well you know each note. Notes you don't know very well are presented more often. Notes you do know well are presented less often.
Ask Revisy to remind you when it's time to next revise your notes. Revisy will select the most important notes for you to revise so your revision sessions are efficient.
