      Recall before revealing the answer

      Test what you know first, then flip the card and compare your response without passively rereading.

      Review at the right time

      Let spaced repetition prioritise difficult cards and bring them back before the memory fades.

      Backed by memory science

      Spaced repetition schedules each card based on how well you know it, using the same spacing principle shown across decades of research to strengthen long-term memory.

      Cards adjust to what you know

      Rate each card Again, Hard, Good, or Easy, and the next review is scheduled around that answer, so weak cards resurface sooner.

      Build your own decks too

      Create custom decks alongside the pre-made subject sets, for anything you want to phrase in your own words.
