About this app

“Your wrong answer journal, now easy to manage in an app.”

Missnote is a smart wrong answer journal app that helps you manage your wrong answers, exam study, and question review more systematically.
You can easily save wrong questions or important questions by taking a photo and review them efficiently with AI-powered review recommendations.
Without saving them in your photo library or organizing them in a paper notebook, manage your wrong answer journal smartly with just one app.



● Main Features

• Easily save questions with photos and text input
You can quickly save exam questions or important questions with a single photo or by entering text.
Use the scanner feature to neatly scan questions and organize them into your wrong answer journal.


• Systematically manage questions with tags and markings
You can organize questions with tags like [#math, #functions, #mistakes] or mark them with your own icons so you can understand them at a glance.


• Your own question book
You can collect saved questions and create your own question book.
Organize and review them in your own way, such as “exam prep question book” or “math questions I got wrong by mistake.”


• Review mode
You can review your saved questions by checking them again.
The more review records you build up, the more accurate and efficient the question recommendations become.


• AI algorithm recommends review questions
The AI algorithm analyzes learning data and review records to recommend the most efficient list of review questions.
It reflects questions you get wrong often, questions you have not seen for a long time, and questions you marked as important to suggest a more effective review order.
Spend less time choosing what to review and focus more on studying for your exams.


• Forgetting curve-based review recommendations
Based on your recent review dates, it recommends today’s review questions according to the forgetting curve cycle.
It provides efficient review timing so the material stays in your long-term memory more effectively.


• Review reminders
It notifies you about the questions you need to review today.
You can manage your wrong answer journal consistently without missing the right review timing.


• Device sync
You can sync your data across multiple devices such as tablets and phones.
Check and review your saved questions anytime, anywhere.


• PDF creation and printing
You can select the questions you want from your saved questions and turn them into a PDF document.
Use PDF sharing and printing features to solve them again yourself or use them as study materials.

• Students who want to manage their wrong answer journal more conveniently in an app

• People who want review questions to be recommended automatically
