Questions
Is Flipwren free?
Yes. Make up to 3 decks with as many cards as you like, study them with spaced repetition, take multiple-choice tests and print your cards, with no account and no ads. Pro is $4.99 once.
What is spaced repetition?
After each card you say how well you knew it: Again, Hard, Good or Easy. Cards you know come back after longer and longer gaps (1 day, 3 days, about a week, then weeks); cards you miss come back the same day. You study only what is due.
Can I bring my Quizlet or Anki cards?
Yes. Paste text with one card per line, the term and definition separated by a tab, a dash, a colon or an equals sign. Quizlet's and Anki's text exports use a tab, which Flipwren detects.
How do printed cards work?
Print fills each page with rows: the front on the left, the back on the right. Fold the sheet down the middle line, then cut along the rows, and every card has its answer on the back.
