Your flashcard app, completely free. Lotus helps you build your own study cards and return to them with spaced repetition. MAKE THE CARDS YOU NEED Create cards with text, images or questions. Keep a simple note on one side, add an answer on the other, or use a two-way card to practise both directions. RECALL BEFORE YOU REVEAL Think through the answer before checking it. On iPad, use Apple Pencil to work in the scratch area as you study. REVIEW AT THE RIGHT TIME Rate how each card went. FSRS spaced repetition schedules the next review. See what is due today, start a short round, or practise an entire deck. Mixed up two cards? Pair them, and next time you see both. KEEP YOUR STUDY SIMPLE Organise decks by name, colour and icon, and arrange them as you like. Add your own images and questions, and search your cards. WORKS WITH MIMOSA AND TRELLIS Make cards from your mimosa highlights, and link a deck to a Trellis project to study it from Today. Your core flashcards work without an account. Optional iCloud sync keeps your study data, pictures included, across your Apple devices. Designed for iPad and iPhone. Available in ten languages. Flashcard creation and review are free. The optional connection to highlights in mimosa requires mimosa Pro.
