Flashcards with a real spaced-repetition engine — and no ads, no sign-up, and no paywall creep. Native on iPhone, iPad, Mac and Apple Watch. iCloud sync included free. Full Anki and CSV import and export, so your cards stay yours. SCHEDULING YOU CAN SEE • Proven SM-2 scheduling, with FSRS available as an optional smart schedule — fewer reviews at the same retention. • Every grade button shows the interval it will produce before you choose it. • Review priority per interest and per deck, so limited study time goes where it matters. • Postpone a card, deck or interest without lying to the algorithm. Holds are stored separately and never touch your memory data. • Leech detection suggests retiring cards you keep failing. CARDS FOR ANY SUBJECT • Cloze deletion (fill in the blank), using Anki-compatible syntax. • Typed answers, with an automatic correct / close / incorrect verdict. • Markdown, LaTeX maths, syntax-highlighted code and tables. • Images with descriptions, read out by VoiceOver. • Tags that cut across decks, plus search over every card you own. BRING YOUR OWN AI JustFlip writes the prompt for whichever chat AI you already use, then imports the answer straight back as cards. No daily caps, no extra subscription, and you review every card before it enters a deck. BUILT FOR APPLE PLATFORMS • Home-screen widget with your due count. • Siri and Shortcuts: ask how many cards are due, or start a review. • Spotlight finds your cards from the Home Screen, matched on either side. • Apple Watch review on your wrist. • Cards read aloud, with per-card language and pronunciation control. YOUR DATA, VISIBLE AND PORTABLE • Works fully offline. No JustFlip account, ever. • iCloud sync shows its last successful sync, with a troubleshooting screen when something looks wrong. • One-file backup, and statistics export as CSV or JSON. ACCESSIBILITY VoiceOver labels throughout, Reduced Motion support, and non-colour indicators when Differentiate Without Color is turned on. FREE AND PRO Free covers up to 3 interests with 5 decks each, with the full scheduler and no ads. JustFlip Pro lifts those limits and adds listening and advanced statistics, as a monthly or yearly subscription or a one-time lifetime purchase. A one-time 7-day trial unlocks the Pro features so you can try them first.

Truly Simple Flashcards is a clean, no-subscription spaced-repetition app for iPhone, iPad, and Mac. Whether you're a student cramming for exams, a language learner building vocabulary, a professional studying for boards, or an Anki refugee looking for a modern alternative, this app does the core job exceptionally well and stops there. Make decks, add cards, and study. The app decides when to show each card again using FSRS, which is the same modern spaced-repetition algorithm power users trust. By asking you to grade how hard a card was to recall, the schedule adapts, so you spend your time on the cards you're about to forget. Format your cards with bold, italics, and colors, keep related decks together in groups, and add audio when hearing something matters as much as reading it. Bring in your existing decks from Anki or a spreadsheet, export your decks to use elsewhere, study seamlessly across all your Apple devices, and own your software forever. Features: • Smart scheduling: Uses the proven FSRS algorithm to adapt to your memory, with an adjustable "target retention" rate per deck. • Two card types: Create classic front-and-back cards, or use fill-in-the-blank (cloze) cards to memorize words in context. Images are fully supported on either side of the card. • Formatting and color-coding: Make words bold, italic, or underlined, and color-code your cards with five text colors and four highlights. Colors stay readable in light and dark mode. • Audio on your cards: Attach audio to the front, the back, or both. Add an existing audio file, or record it right in the app. • Deck groups: Keep related decks together, like every topic in a unit. Groups fold away when you don't need them and show what's due inside. • Simple imports: Bring your existing decks with you. Import Anki files (.apkg / .colpkg, including the newest formats) or CSV/TSV spreadsheets. Anki subdecks arrive as groups, with their formatting intact. • Two-way study: Turn on two-way review to test your recall back-to-front, which is especially effective for learning vocabulary words. • Paced learning: Set a daily limit for new cards so a huge imported deck doesn't overwhelm your study session. • Study ahead: Caught up for the day and want more? Study tomorrow's cards early. • Undo a grade: Tapped the wrong button? Undo brings the card back so you can answer it again. • Flip-through mode: Review a deck casually without affecting your spaced-repetition schedule. • Reliable device sync: Your decks sync privately and securely through your own personal iCloud account across your Mac, iPad, and iPhone. • Genuinely accessible: Built natively for Apple devices with full VoiceOver support, Dynamic Type for comfortable reading, light/dark modes, and calm, minimal motion. • Pay once, keep forever: Use one deck for free with unlimited cards. Unlock unlimited decks with a one-time, lifetime in-app purchase. No subscriptions, no ads, no hidden fees or data-harvesting.
