Shameless plug: I made a small webapp to memorize Japanese vocabulary through spaced repetition and a Tinder-like interface: https://core.cards/ https://core.cards/ I made it for myself, but someone else might find it useful. It is the alternative of carrying a huge stack of cards as I used to do. Requires Github login though to syncronize through devices.
