GlanceCards

Micro-flashcards on a real spaced-repetition scheduler — learn in glances, all on your device.

Spaced repetition works because forgetting is predictable. Ebbinghaus mapped the curve in the 1880s, and the practical consequence is that reviewing just before you would have forgotten is dramatically more efficient than reviewing on a fixed schedule — the same retention for a fraction of the reviews.

The scheduler is therefore the product, not the cards. What separates a real implementation from a flashcard list is that each card carries its own interval, growing when you recall it and collapsing when you do not. Short sessions suit it well: the algorithm cares about the spacing between reviews, not about how many you do at once.
