About this app

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.

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.
