Words come back right before you'd forget them
Flip a card, then tap I Know It! or Not Quite. Words you know come back after longer and longer waits until they're mastered. Choose a Quick schedule for cramming, Long-term for lasting memory, or set your own.
Browse 63,000+ words like a real book
Flip through the dictionary page by page. Tap a word to add it to your queue, or press and hold to peek at its meaning and an example sentence.
See every word used in a sentence
Each card shows the definitions and a real example sentence, so you learn how a word is used, not only what it means.
Watch your vocabulary grow
See what's due today, how many words you're learning, and how many you've mastered.
No account. No ads. No tracking.
Rare among vocabulary apps: FlipDict doesn't collect anything. Your words stay on your device, and the app works without an internet connection.
Questions
Who is FlipDict for?
Native English speakers and advanced learners who want a bigger vocabulary: writers, readers, students preparing for the GRE or SAT, and anyone who loves words.
How does the review schedule work?
FlipDict uses spaced repetition. You see a new word right away, then again after longer and longer waits, by default 10 minutes, 30 minutes, 1 day, and 3 days. Pass the last review and the word is mastered. You can pick a Quick, Standard, or Long-term schedule, or build your own.
Do I need an account or internet?
No account, and no internet connection is needed. The whole dictionary is inside the app, so it works on a plane or the subway.
Is it free?
Yes. FlipDict is free, with no ads and no subscriptions.
Does it work on iPad?
Yes, FlipDict runs on iPhone and iPad.
Can I suggest a deck?
Please do. Tap Request a Deck in the app, or email flipdictapp@gmail.com. New decks are chosen from these requests.
