01 · SEE

A scene, not a card.

A crisp low-poly image gives every new meaning a place to live.

02 · PRACTISE

Stay in the language.

Each wheel controls one part of the same sentence—always in the language you are learning. Meanings appear only when you ask.

03 · CHECK

Know it now.

Immediate visual feedback keeps each exercise focused and clear.

04 · RETURN

Meet it before it fades.

FSRS adapts the next review to the strength of your memory.

Adaptive memory

Progress that accounts for forgetting.

Kulma estimates what you can recall now—not simply what you once completed. Every answer updates the next review, so fragile material returns sooner and solid memories get room to breathe.

One Fluency point represents roughly one fully recalled vocabulary item. Your score stays honest by changing as memories strengthen or fade.
