Flash Stack - Revision Cards

Flash Stack helps you build simple flashcard decks, review what is due, and keep track of your progress without clutter. It is especially useful for GCSE revision, A Level revision, mock exam prep, and steady day-to-day study.

Create custom decks for topics, formulas, essay plans, key quotes, definitions, case studies, dates, vocabulary, and revision cards for the subjects you actually study. Add cards one at a time, bulk import larger sets, or export a deck when you want to back it up or move it elsewhere.

Study sessions focus on the cards that are ready for review. Reveal each answer, rate how well you remembered it, and Flash Stack schedules the next review using the SM-2 spaced repetition approach.

Features:

- Create unlimited custom decks
- Add and edit question-and-answer cards
- Bulk import cards from text, CSV, TSV, or JSON files
- Export decks as JSON
- Review due cards in focused study sessions
- Rate cards as Again, Hard, Good, or Easy
- Track review activity, retention, streaks, and upcoming workload
- Set an optional daily reminder
- Built with support for VoiceOver, Dynamic Type, and Reduce Motion
- Clear labels, spoken summaries, and accessible study controls
- Works without an account

Whether you are preparing for GCSE mocks, A Level papers, class tests, or personal study goals, Flash Stack is designed for quick daily revision. Use it for science facts, maths formulas, history dates, English quotes, languages vocabulary, and other exam content you need to remember properly.
