"Turn every wrong answer into your next score gain." Missnote is a mistake journal for students, test takers, and anyone preparing for exams. Save missed questions, confusing problems, and questions you want to solve again as photos or text. Organize them with tags, markings, and custom notebooks. AI review suggestions and spaced repetition-based timing help you know what to review today, so your mistake log becomes a smarter study routine. ● Key Features • Save questions quickly with photos or text Capture exam questions, past paper problems, workbook pages, and important exercises with a photo, or type them in directly. Use the scanner feature to keep question images clean and easy to review. • Organize mistakes with tags and markings Add tags such as #math, #functions, #carelessMistake, and mark questions with your own icons. Find the right problems fast by subject, chapter, exam range, difficulty, or mistake type. • Create your own review notebooks Group saved questions into custom notebooks. Build sets like “SAT math review,” “final exam mistakes,” “certification practice,” or “questions I keep missing,” then review them whenever you need. • Review mode Go through saved questions one by one and check them again. Do more than look at the answer: write why you missed it, what concept you forgot, and how to solve it correctly next time. • AI review suggestions Missnote recommends questions that may be worth reviewing now based on your review history, last viewed date, important marks, and frequently missed problems. Spend less time choosing what to study and more time improving your weak spots. • Spaced repetition-based review timing Manage today’s review targets by focusing on questions you have not seen recently or questions that are ready to be reviewed again. Build a steady review habit so important mistakes do not disappear from memory. • Review reminders Get notified when you have questions to review today. Keep your mistake journal routine going even during a busy exam season. • Continue across devices Sync your data across your phone, tablet, and other devices. Review your saved questions at school, in the library, at home, or anywhere you study. • Create and print PDFs Turn selected questions into a PDF, share it, or print it. Useful when you want to solve wrong answers again on paper or make a quick review sheet before an exam. [Recommended for] • Students who want a faster alternative to a paper mistake notebook • Test takers preparing for school exams, SAT, ACT, GCSE, A-Level, AP, certification exams, or college tests • Anyone who wants to save question photos and organize them with tags • Learners who do not want to miss review timing with AI suggestions and reminders • Students who want to export wrong answers as PDFs and solve them again Missnote is not just a place to store questions. It helps you manage wrong answers, organize study notes, choose what to review, set reminders, and print PDF review sheets in one study app. The habit of reviewing mistakes can make the difference on exam day.

Read 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).
