FlipStudy is a fast, private flashcard app for students and language learners. Create a deck, add cards, and study with a simple flip-and-rate flow that uses spaced repetition (a Leitner box system) to bring back the cards you miss more often — so you spend your time on what you haven't learned yet. TRANSLATE AS YOU GO Type the English side of a card and let the built-in translator fill in the other side — Italian, Spanish, French, German, Portuguese, Japanese, or Chinese. It runs on your device: free, private, and offline-friendly. Prefer to type the answer yourself? You can. HEAR IT SPOKEN Tap Listen to hear the translation read aloud in its own language, not an English voice — great for pronunciation and listening practice. STUDY THAT STICKS - Spaced repetition schedules reviews automatically - Add new cards mid-session, right when a set is done - Clean, distraction-free flip cards PRIVATE BY DEFAULT No accounts. No analytics. Your decks stay on your device. An optional cloud translation feature (off by default) uses your own API key and sends text directly to your chosen provider — never through us.
