Wrong today. Right on exam day. ErrorBank keeps the questions that matter: the ones you got wrong, couldn't solve, or know will come back. Snap them, solve them again with Smart Review, and never lose the same point twice. WHY IT WORKS • Your own questions, not a generic question bank • Smart Review brings each one back at the right time • Write and draw on any question, with Apple Pencil on compatible iPad • Works offline; everything stays on your device HOW IT WORKS 1. Snap or import a question you got wrong or couldn't solve. 2. Tag it, write your solution and set a goal from 1 to 10. 3. Solve it again whenever it comes back, until it's mastered. SNAP IT Photograph a question or pick an image, crop it and tag it by subject, topic and difficulty. Search and filters find it in seconds. SOLVE IT Write on the question or on a blank page, by touch on iPhone or with Apple Pencil on compatible iPad. MASTER IT Set a goal of 1 to 10 correct solves for each question. Every success pushes the next review further out; tough questions return sooner, and a miss never erases your progress. ORGANIZED BY SUBJECT Subjects, topics and tags keep hundreds of questions tidy, with solved and open counts at a glance. See which topics your open questions pile up in and focus where it counts. WATCH YOURSELF IMPROVE Accuracy, session results, daily stats, study streaks and reminders when questions are due. Share questions or export them as a PDF. MADE FOR • Students preparing for entrance and national exams • High school students who want to stop repeating the same mistakes • Anyone who learns best by solving problems FOR EVERY EXAM Entrance exams, finals or tomorrow's quiz. ErrorBank isn't a question bank or an automatic solver and isn't affiliated with any exam organization. There's no automatic sync between iPhone and iPad. PRIVACY AT A GLANCE ErrorBank collects no personal data. There's no account, no ads and no tracking: your photos, notes and drawings stay on your device. ErrorBank. Wrong today. Right on exam day.
