SpaceRep lets you review notes created with Evernote according to the spaced repetition method.
The app displays notes that should be reviewed today as well as an overview of whats coming up for review this month.
Just add the notes you want to review to the auto-generated "Spaced Repetition" notebook and your set to go!
Note:
The application is meant for scheduling repetition of subjects. It is not optimised to be a flash-card tool for notes with individual questions.
