Mistake Review

Turn missed questions into private review cards with answer masks, spaced review, and printable redo sheets.

Mistake Review helps you turn your own missed questions into a private review system. Capture homework, test questions, textbook exercises, or screenshots, then add answer masks so you can redo the question before revealing the answer.

Built for students, parents, and exam prep learners who want a clean wrong-answer journal without uploading study material to a server.

Key features:

• Capture missed questions from camera scans, photos, or text
• Add answer masks directly on the original question image
• Review cards with active recall and reveal answers when ready
• Rate each review with Again, Hard, Good, or Easy
• Use spaced review scheduling to know what to study next
• Organize mistakes by subject, exam, tags, and reason
• Search OCR text from saved question images
• Export printable redo sheets as PDF (Mistake Review Pro feature; requires a separate in-app purchase or subscription)
• Set local daily study reminders
• Back up and restore your local study data

Privacy-first by design: your cards, images, OCR text, tags, notes, review logs, and settings are stored locally on your device. Mistake Review does not include a shared question bank, does not require an account, and does not upload your study material to an external study service.
