Vocafly

Vocafly is a vocabulary learning app built around swipeable flashcards and a spaced repetition system. It helps you memorize words, phrases, and grammar patterns in any language — at your own pace, on your own schedule.

There is no account to create, no server involved, and no internet connection required. Everything stays on your device.

The core mechanic is simple: a card appears with a word or phrase, you recall the meaning, then swipe right if you got it or swipe left to see it again later. The spaced repetition system schedules each card based on how well you know it, showing harder items more often and gradually spacing out the ones you have mastered.

You can organize vocabulary into separate decks — one per language, topic, or learning goal. Each deck tracks its own progress independently. The home screen displays all your decks as a grid of cards, so your study material is always one tap away.

The app works entirely offline. No registration, no subscription, no in-app purchases. Just open it and study.
