## What is Klappkarten?

Klappkarten turns your phone into a flashcard. When folded, the question appears large on the outer display. Think it over, then unfold slowly: the answer becomes visible bit by bit as you open it. Fully open, you see the explanation and an example and rate how well you knew it. That decides when the card comes back.

• Reveal by unfolding; on any iPhone, pull down or tap a button
• SM-2 spaced repetition: what you know comes back less often, what you struggle with more often
• Again, Hard, Good, Easy, plus undo for the last card
• Your session picks up exactly where you left off after an interruption or a restart
• CSV import (Excel, Numbers, spreadsheets) with column mapping and preview
• .apkg import for existing flashcard packages
• "Due Today" widget and a daily reminder at your chosen time
• Includes a sample deck to try it out

Free, no ads, no tracking. A small side project, built for the fun of folding. Unlimited decks and reviews, CSV and .apkg import, statistics and widgets included.

Your cards stay on your device. No account, no tracking.
