Mistake Coach
A personal study companion that turns missed questions into a structured review system.
Don’t collect your mistakes. Fix them.
Mistake Coach is a study app that helps students save the questions they get wrong, understand why those mistakes happened, and solve them again at the right time.
Capture a question with your camera or choose an image from your photo library. Add its subject, topic, and the reason behind the mistake. Mistake Coach then schedules future reviews based on your performance.

Do not let missed questions disappear inside old notebooks, worksheets, and test papers. Mistake Coach keeps them organized in a focused learning system.

Review at the right time
Mistake Coach does more than store questions. It schedules the next review according to how confidently you solved each one.
Difficult mistakes return sooner, while confidently solved questions move to longer review intervals.
Practice any question when you need it
When studying with a teacher or focusing on a particular topic, you can open any saved mistake and solve it again.
A free-practice attempt can be recorded without changing the planned review date. You can also count the result as a scheduled review.
