Stop making the same mistake twice. MistakeLab is the ultimate wrong answer journal (error log) and spaced repetition assistant engineered for elite students preparing for high-stakes competitive exams. Whether you are studying for the SAT, ACT, GMAT, GRE, LSAT, MCAT, CFA, or college finals, keeping a structured "error log" is the single most effective strategy recommended by top-scoring students (99th percentile) worldwide. MistakeLab automates this process, transforming your failures into exam-day breakthroughs. ▸ SNAP & EXTRACTION WITH ON-DEVICE OCR Stop wasting precious study time typing out long prompts. Instantly take a photo of any failed question from a prep book, worksheet, or computer screen. Apple's native OCR (Live Text) extracts the question text locally in seconds, creating a clean record automatically. ▸ DIAGNOSE THE ROOT CAUSE (COGNITIVE TAXONOMY) To fix a mistake, you must understand why you made it. Classify your errors under 5 distinct cognitive categories: • Content Gap: You did not know the underlying formulas or rules. • Careless Mistake: You knew the concept but made a silly calculation slip. • Misread: You missed a crucial word (e.g. "except", "not") or misread the question stem. • Concept Trap: You fell for a logical trap or distractor option. • Time Pressure: You ran out of time or panicked under the clock. Add your custom notes and actionable remediation rules (lessons learned) to ensure you don't repeat them. ▸ SCIENTIFIC SPACED REPETITION (SM-2 SRS) Reviewing a correction immediately after seeing it creates a false sense of fluency. Powered by a local adaptation of the SuperMemo-2 (SM-2) algorithm, MistakeLab schedules review sessions at mathematically optimal intervals (Day 1, Day 3, Day 7, etc.) based on your performance. • Daily Review Queue: Easily work through questions scheduled for revision today. • Fluid gestures: Swipe right to master, swipe left to keep in queue. • Rich haptic feedback via CoreHaptics for an engaging, physical review loop. ▸ ANALYZE YOUR WEAKNESS PATTERNS Stop guessing what to study. The analytics engine uses native Swift Charts to visualize: • Cognitive Failure Breakdown: Check if you suffer more from careless slips or core concept gaps. • Topic Weakness Matrix: Find which exam sections (e.g. Quantitative, Reading Comp) have the highest error density. • Learning Curve: Monitor your progress as you turn active errors into mastered concepts. ▸ 100% OFFLINE & PRIVACY FIRST Your study data is yours alone: • 100% Offline: No account signups, no external servers, no internet connection required. Review anywhere, even in library basement study rooms. • Zero Data Collection: We do not collect, store, or transmit your name, text, or photos. • PDF Booklet Export: Generate a clean, formatted PDF of your mistakes to print out or share with your tutor. Eliminate your blind spots, boost your score, and walk into your exam room with absolute confidence. Start your error journal with MistakeLab today. Support: contact.devotellix@gmail.com
