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) Why you'll remember with Flips ・Science-based: spaced repetition tuned to the forgetting curve optimizes your review timing ・Built for focus: a stripped-down interface, studying in two taps ・Priorities made visible: the forgetting gauge and "due today" count remove the guesswork ・Built for habit: streaks keep you coming back Common ways people use Flips ・Students: vocabulary, historical dates, formulas, test prep ・Working professionals: certification vocabulary, technical terms, on-the-job knowledge ・Language learners: vocabulary across any language you're studying What Flips values ・Simple and fast: built to help you focus purely on remembering ・Visible progress: progress, streaks, and forgetting risk, always in view ・Flexibility: build your own decks or import to fit any subject Start for free, and build a study habit around reviewing right before you forget.
