Spaced repetition, built into the device.

Cardolo is a dedicated flashcard device that schedules reviews based on how well you know each card, helping you focus on what needs attention instead of repeating everything equally.

Real scheduling, not flat repeats

Every card tracks how well you know it. Cards you find hard come back sooner. Cards you've nailed come back further apart — the actual mechanism behind long-term memory.

No screen but the one that matters

Cardolo boots straight into your decks. No lock screen, no notifications, no app switcher standing between you and the next card.

Load decks without installing anything

Drag in a text file, paste your own list, or import straight from an Anki export — all from a page in your browser. No software required.

Again — forgot it, review soon Hard — knew it, barely Good — knew it, on schedule Easy — knew it cold, review much later
