CalligraEverything you need to learn. Nothing that distracts.
The Calligra app combines flashcards, spaced repetition and statistics in a minimal interface – with light and dark mode.
Decks and cards
Create, rename and delete decks. Create, edit and search cards with a question and an answer.
Study mode
Tap a card to flip it – then answer “Right” or “Wrong” with a button or a swipe. Choose due cards only or all cards, with a progress bar and haptic feedback.
Spaced Repetition
A simplified SM-2 algorithm: cards you answer correctly come back at ever longer intervals.
Statistics
Streak, accuracy, daily goal and a chart of the last seven days – to help you keep going.

CSV import and export
Bring in existing card collections or back up your decks.
Light and dark
A switch in the deck list; your choice is saved.
