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.
