JustFlip is a focused flashcard app for learning languages, science, programming, and anything else worth remembering. Create rich cards, review with spaced repetition, and keep your knowledge with you across iPhone, iPad, Mac, and Apple Watch.
Hi Product Hunt! I’m Daniel, the maker of JustFlip.
I built JustFlip because many flashcard apps made me spend too much time managing the system instead of learning. I wanted a calm, focused place where I could create cards quickly, see exactly when a card would come back, and study anything—from languages and biology to maths and code.
JustFlip combines a visible spaced-repetition scheduler with rich cards: Markdown, LaTeX maths, syntax-highlighted code, images, audio, cloze deletion, and typed answers. It works offline, has no JustFlip account, includes iCloud sync, and supports iPhone, iPad, Mac, and Apple Watch.
The free version is useful on its own. Pro is for people who need more interests and decks, listening, and advanced statistics.
I’m launching because JustFlip! currently needs its first real community of learners. I’d love feedback on three things:
1. Does the review flow feel fast and understandable?
2. Which feature would make you use it every day?
3. What would make you switch from your current flashcard app?
If you try it, please tell me what you studied and where the experience felt unclear. I’ll be here throughout launch day and will use the feedback to shape the next release.
