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

Verdict
The clearest difference is in-app purchases: KujiraTimer at none against FlashSnapCards's 1. FlashSnapCards's advantage is ads (none vs shown) and update cadence (fortnightly vs every 5 months). On price, device support and iOS requirement there is nothing between them.
