FlipDict

Build a bigger vocabulary, one word at a time.

FlipDict is a focused, no-nonsense vocabulary builder for native speakers, advanced English learners, writers, and anyone who wants to know more words. Choose from curated themed decks — emotion vocabulary, words from classic novels, rare and beautiful words, GRE prep — or browse a real dictionary of 63,000+ English words and pick the ones you want to learn. Then let spaced repetition do the rest.

WHY FLIPDICT IS DIFFERENT

Most vocabulary apps lock you into a single word list. FlipDict gives you the whole dictionary plus a growing library of curated decks — and lets you study them all with proven spaced repetition. Whether you're prepping for the GRE, sharpening your business communication, expanding your emotional vocabulary, or savoring the language of classic literature, FlipDict adapts to what you want to learn.
