What it is
A flashcard app that schedules each card just before you would forget it. Ten to twenty minutes a day covers a surprising amount of material, and shared decks exist for most languages and exams.
Best for
Language and memory coaches who want learners doing daily review between sessions, on a schedule the software keeps for them.
Watch out for
The default interface is plain and the settings are intimidating. Hand learners a ready-made deck and a daily target rather than the whole manual.
