MistakeBook
Read full descriptionHide full description
MistakeBook turns “mistake review” into a sustainable study workflow. Inspired by the forgetting curve and spaced repetition, it automatically schedules your next review based on your familiarity—so you remember more in less time. Quickly add questions and answers via Camera / Photos / Paste—no more paper cut-and-paste. Use the built-in crop tool for precise framing, then handwrite annotations and hide answers (masking) to start reviewing right away. All content and metadata (subject, learning content, reason analysis, tags, created time, etc.) are stored locally on your device, and the app works offline. Key Features “+” Add Mistakes: Create question/answer sets from camera, photo library, or paste. Organize with categories and tags. “Today” & “Upcoming”: View what to review, reminders, and review history. Auto-schedule by star-rated familiarity; mastered items move to “Completed.” “Stats”: Identify frequent mistakes and weak areas with data to improve efficiency. “All”: Export A4 PDFs (questions/answers/reviews) for sharing or printing. Support ZIP export/import for backup and exchange. “Exam Paper”: Select mistakes and export as PDF or editable ODF for printing and practice. “Settings”: Set daily reminder time, manage subscriptions, manage subjects/learning content/reason analysis, and import ZIP backups/shared files. Free plan: up to 30 mistake entries. Subscription: create unlimited mistake entries (auto-renewable).

Verdict
The clearest difference is in-app purchases: CorrectNoteLite at none against MistakeBook's 1. CorrectNoteLite also leads on iOS requirement (11.0 vs 18.6). MistakeBook's advantage is update cadence (every 2 weeks vs every 7 months). On price, ads and device support there is nothing between them.
