## Core capabilities

- **Exam IQ**: On-device CoreML model that predicts your exam-day score with confidence intervals, using Item Response Theory (IRT) and Bayesian inference over your answer history.
- **Adaptive study plans**: The app picks your next session — weak-spot drills, knowledge-decay refreshes, mock exams — based on your current ability estimate per domain.
- **Exam simulator**: Full-length mock exams under real timing and question distribution for each Microsoft exam.
- **Knowledge decay tracking**: Spaced-repetition signals flag topics where your retention has dropped before exam day, with targeted refresher sessions.
- **Question types**: Multiple choice, multi-select, drag-and-drop ordering, hotspot, case studies — matching the formats Microsoft uses on the real exams.
- **Why Wrong**: For incorrect answers, on-device Apple Foundation Model generates targeted explanations grounded in the question's correct rationale.
- **Offline-first**: Works fully without a network. No telemetry, no analytics on user behavior, no account required.
- **Apple ecosystem**: Native SwiftUI on iPhone and iPad; Live Activities for active study sessions; Apple Watch glance for streaks and XP.

## Differentiation

Azure Mastery is built for serious certification candidates who want to know *when they're ready* rather than just drilling questions. It is differentiated from generic flashcard apps by:

1. ML score prediction calibrated to Microsoft's pass thresholds, not a raw % correct.
2. Per-domain ability estimation — you see exactly which of an exam's domains is dragging your predicted score down.
3. Knowledge decay alerts so you don't lose old material while learning new domains.
4. 100% on-device computation — Exam IQ, Why Wrong explanations, and study plan generation never leave the device.
