Thanks for checking it out! A spaced repetition app that I've used is Memrise (I used the web app), and I found it to be pretty effective. They gamify the experience by having 'plants' that you have you to water every so often. The app I wrote keeps things pretty simple, and is designed to re-create the physical stack of flashcards (which is a proven technology I think). But spaced repetition is definitely a good approach too, and apparently it's backed by findings in neuroscience.
