## What is RakuTan?

A flashcard app for anything you want to remember.
English vocabulary, exam terms, history dates, drug names, work jargon — if you can write it on a card, you can learn it.

■ Reviews arrive right before you forget
New cards start in the Learn corner. Answer "Got it" three times in a row and a card graduates to Review.
Reviews come back after 1 → 3 → 7 → 14 → 30 days, timed to the forgetting curve so each repetition counts. Clear the 30-day review and the card is mastered. Forget along the way? No problem — it simply starts over in Learn.

■ Adding cards is fast
- Add cards one by one, or paste a whole table copied from Excel or Google Sheets
- Import CSV files
- One tap copies an AI prompt: paste it into ChatGPT or any AI, paste the answer back, and get a full deck complete with example sentences and memory tips

■ Designed for studying
- A highlighter marks the word you're learning; answers appear in red ink — your eyes go straight to what matters
- Flip cards as many times as you like
- Read-aloud with the built-in system voices (English and Japanese are detected automatically)
- Organize with multiple decks
