Flips is a flashcard app that brings back each card right before you're about to forget it. Built on the forgetting curve and spaced repetition (SRS), it works for anything worth memorizing — vocabulary, exam terms, dates, professional jargon, and more.
Key Features
・Just-in-time review (SRS)
Cards resurface automatically at the best moment to review. Mastered cards space out; shaky ones come back sooner — the shortest path to remembering.
・Simple, fast study sessions
Open the app and start right away. Swipe or pick from 4 choices — nothing gets in the way of focus.
・Memory home screen
A chart shows what you've learned, what's fading, and what's new at a glance. Today's study count is always clear.
・Streaks to build the habit
Your study streak is shown like a calendar, so daily effort visibly adds up.
・Forgetting gauge & levels
See each card's "risk level" in your deck list, so you always know what to review first.
・Create decks & import
Build a deck in minutes, or import from CSV/TSV.
・Notifications at the right time
Get reminded exactly when review will be most effective.
・Text-to-speech (TTS)
Hear pronunciation for listening practice or a quick check. (Supported languages depend on your device; more are added over time.)
Great for
・Language vocabulary: words, phrases, listening practice — Spanish, French, Japanese, or any language
・School & exams: history dates, science terms, formulas, standardized test prep
・Certifications: professional exams, medical, legal, and IT terminology
・Anything else: whatever you need to memorize
How it works (3 steps)
1. Pick a deck or make one (ready-made vocabulary decks, or build your own)
2. Start studying (cards you're about to forget come up first)
3. A little every day (streaks and charts make progress visible)
