HabitTracker

HabitTracker is an iOS utility that lets users record daily habits, schedule flexible repetitions, and monitor related mood, energy, productivity, and sleep data. The app presents streak counts, grace‑day allowances, and visualizations such as a calendar view and a GitHub‑style heatmap to help users see long‑term patterns.

In addition to basic logging, HabitTracker offers detailed statistics on completion rates, time‑of‑day trends, and per‑habit performance. Optional premium AI features analyze the collected data to surface habit correlations, predict mood shifts, flag streak‑risk situations, and provide a weekly digest of insights.

The application integrates with Apple HealthKit for automatic completion of health‑related habits, supports widgets, Siri shortcuts, and live activities, and operates without ads or external data collection. Core functionality is free, while the AI‑enhanced analysis is available through a subscription.
