FlashSnapCards

Snap your textbook and it becomes a flashcard. Then just flip through today's cards. Making flashcards by hand is a chore, and when your exam is close it's hard to know whether you'll finish in time. FlashSnapCards eases both at once. Photograph a page and crop the part you want to learn, and you have a card. It also reads the text in your photos, so you can make card after card from the same picture. Then spaced repetition counts back from your exam date and serves just today's share, right before you'd forget it. • Free to start, no subscription (Premium is a one-time purchase) • No third-party ads (the only promotions are the developer's other apps) • Your records stay on your device (no account needed; photos are never uploaded) WHAT YOU CAN DO • Photo cards: snap your textbook or notes and crop just what you need • Text recognition: read the text in a photo to fill in questions and answers faster • Many cards from one photo: tap "Save & make another from this photo" to keep going • Text cards: question on the front, answer on the back • Spaced repetition: cards come back right before you'd forget them • Exam countdown and finish forecast: see each day whether you're on pace • Three ways to study: flip, multiple choice, or type the answer • Stats: cards mastered, progress by deck, and your weak cards • Daily goal, study streak, and study reminders • Edit and delete cards anytime • Works on iPhone, iPad, and iPhone Duo • English and Japanese WHO IT'S FOR • Students facing a mountain of facts before finals or entrance exams • Working adults studying for a certification in spare moments • Anyone memorizing terms, dates, or vocabulary • Anyone who has started a flashcard habit and let it slip PRIVACY • Your cards and study history are stored only on your device • Text recognition also runs on your device • The only network use is showing the developer's other apps

Rewise

Remember it right before you forget it. Rewise turns the most current spaced-repetition science into the fastest way to study on iPhone. Medicine, exams, languages. It ends "there is too much to memorise" with actual science. Why do you forget it after all that work? Because the interval between reviews does not match your forgetting curve. The FSRS scheduler predicts the moment you are about to forget and asks you then. Set your target retention anywhere from 70% to 97%. Fewer reviews, deeper retention. How much longer is today going to take? Every answer button tells you when the card comes back — tomorrow, in 3 days, in 10 days — so you can see the end of it. When today runs out, "Study all now" adds more without disturbing the schedule. Isn't making the cards the part that kills the habit? Point it at a photo, a PDF or pasted text and it drafts the questions and answers for you, entirely on the device. Flashcard packages (.apkg / .colpkg, exported with legacy support enabled) and CSV files import directly. Everything is processed on the device and we run no servers of our own. Your cards leave the phone only if you turn on iCloud sync yourself. Is there only one way to memorise something? Basic cards, cloze deletion, image occlusion that lifts one mask at a time, and multiple choice. Red sheet mode (free) writes the answer in red under a see-through red sheet; slide it down to check yourself. Read-aloud uses the voices already on your device, so it speaks more than 30 languages. Do I need a computer? No. Building cards, masking images, importing files — all of it finishes on the device. Turn on iCloud sync (Pro) and your iPhone and iPad stay joined, with no sync button to press. But can you actually keep it up? Study reminders, and widgets for the Home and Lock Screen. Six months of heatmap, a forecast of the workload ahead, and your real measured retention: progress you can actually see. The haptics and sounds feel good, and they can be switched off. Won't it hurt my eyes at night? There is a paper-textured screen and a warm dark mode for late sessions. Pick your app icon too. What does it cost? Free, for up to 4 decks and 300 cards. The spaced repetition itself is never rationed. Rewise Pro (subscription) lifts the card limit and opens all-device sync, image occlusion, multiple-choice, typed-answer and audio cards, read-aloud, unlimited drafted cards, six-month statistics, alternate app icons, imports, and full JSON and printable PDF export. Exporting your cards as CSV is free on every plan. Yearly is the best value and comes with a 7-day free trial. A lifetime unlock is also available for anyone who prefers not to subscribe. What you learn today — for exam day, and long after. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://revot.jp/apps/rewise/privacy.html
