Turn every wrong answer into a better learning opportunity.
Mistake Coach is a focused study and review app designed for students who want to understand their mistakes, revisit difficult questions, and build stronger long-term knowledge.
Instead of letting missed questions disappear inside notebooks, worksheets, test papers, or photo galleries, Mistake Coach brings them together in one organized learning system.
CAPTURE THE QUESTIONS YOU MISSED
Take a photo of a question or choose an existing image from your photo library. Add the subject, an optional topic, and a note that may help you understand the question later.
IDENTIFY WHY THE MISTAKE HAPPENED
A wrong answer is more useful when you understand its cause. Mistake Coach lets you record whether the mistake came from:
• A concept gap
• A forgotten rule
• A calculation error
• Misunderstanding the question
• Carelessness
• Guessing
• Time pressure
• Another reason
Recognizing recurring mistake patterns can help you make your future study sessions more focused.
REVIEW AT THE RIGHT TIME
Mistake Coach creates a focused review queue for your saved questions. After solving a question again, choose the result that best describes your attempt:
• Couldn’t Solve
• Struggled
• Solved Easily
Your answer determines the next review interval. Difficult questions return sooner, while confidently solved questions gradually move to longer intervals.
One successful attempt is not treated as complete mastery. Questions progress through the review system over time, encouraging lasting learning instead of short-term memorization.
PRACTICE ANY QUESTION WHEN YOU NEED IT
You do not always have to wait for a scheduled review.
Open any saved mistake and use Solve Now when studying a specific subject, working with a teacher, or preparing for an upcoming exam.
After the attempt, you can choose:
• Just Practiced — records the practice without changing the planned review date
• Count as Review — evaluates the result and updates the next review schedule
This keeps free practice separate from your planned review system.
ORGANIZE SUBJECTS AND TOPICS
Create your own subjects and topics to match the way you study. Edit and manage them from Settings, and use them to keep your saved questions easy to find.
TRACK YOUR PROGRESS
Simple insights and charts help you understand how your learning is developing.
You can view:
• Review activity
• Mastered mistakes
• Mistakes by subject
• Recurring mistake reasons
• Recent progress

Set an optional daily reminder for your preferred review time. Tapping the reminder takes you directly to your review queue.
