📚 Turn mistakes into smarter revision with MistakeBook - Exam Flashcards. MistakeBook is an offline exam flashcards and mistake notebook app for students who want to learn from the questions they get wrong. Capture a question, hide the answer, save the correct method, and review it later with spaced repetition. Instead of letting wrong answers disappear into notebooks, screenshots, or old test papers, turn them into a focused revision system you can use every day. 📸 CAPTURE QUESTIONS IN SECONDS Create flashcards from the way you already study: • Take a photo with your camera • Choose a question from your gallery • Add text questions and answers • Record audio notes • Crop and rotate images before saving No complicated setup is required. Save first, organize later. 🙈 HIDE ANSWERS & TEST YOURSELF Turn photographed questions into active-recall flashcards by masking the answer area. • Draw answer masks over photos • Keep answers hidden until reveal • Review image questions without seeing the solution • Use text, image, and audio content Useful for formulas, diagrams, multiple-choice questions, definitions, worked examples, and exam corrections. 🧠 LEARN FROM EVERY MISTAKE For every saved question you can keep: • Your wrong answer • The correct answer • Why you got it wrong • A short “next time” reminder • Subject, chapter, exam, tags, and source notes Build your own wrong answer notebook and understand which mistakes keep repeating. 🔁 SPACED REPETITION FLASHCARDS MistakeBook schedules review cards so you can focus on what needs attention instead of rereading everything. After revealing an answer, rate your recall: • Again • Hard • Good • Easy Use scheduled review for long-term revision or separate practice for extra exam preparation. ⚡ QUICK 5-MINUTE REVISION Start a focused five-minute study session when you are short on time. Great for daily revision, exam preparation, commute study, quick practice, and repeated mistakes. 📂 ORGANIZE YOUR STUDY MATERIAL Keep your flashcards easy to find with: • Subjects • Chapters • Exams • Tags • Mistake reasons • Search and filters Create your own structure for school, university, entrance exams, competitive exams, certifications, or professional learning. 🎯 FOCUS ON WEAK AREAS See due flashcards, repeated mistakes, weak topics, recent captures, review history, and needs-attention items. 📊 TRACK YOUR PROGRESS Understand how your revision changes over time with: • Reviews completed • Cards reviewed • Review recall • Subject performance • Error-type breakdown • Weak topics • Study activity Your progress comes from your own review history — not a fake exam score or AI-generated prediction. 🔒 OFFLINE-FIRST & PRIVATE Study without creating an account.
