CardFlash: Flashcards & SRS

CardFlash is a simple, offline flashcard app built around spaced repetition. Create as many decks as you like, add cards with a front and back, and CardFlash schedules each card's next review based on how well you remembered it.

Review mode shows one card at a time — tap to flip from question to answer, then rate your recall as Again, Hard, Good, or Easy. A lightweight scheduling algorithm uses that rating to space out easy cards and bring back tricky ones sooner, so your study time stays focused on what you actually need to practice.

The home screen shows how many cards are due today across all of your decks, so you always know exactly what to review next. Each deck tracks its own card count and how many cards you've mastered over time. All decks and cards are stored on your device.

Whether you're learning vocabulary, exam facts, or anything else worth memorizing, CardFlash keeps the workflow simple: add cards, review when they're due, rate honestly, repeat.
