StayOnTrack
An Android-first screen time tracking app that monitors app usage in real-time via Android's UsageStatsManager API, runs a persistent background service, shows system overlay alerts when per-app limits are exceeded, and provides detailed analytics with charts. It includes a dark "Glacier" design system with frosted-glass UI, animated dashboards, and a boot receiver + WorkManager watchdog to survive reboots.

Key Features
01
Real-Time Usage Tracking : Continuously monitors foreground app activity via Android's UsageStatsManager API, computing per-app minutes from foreground/background event deltas, filtering out 14 system packages.
02
Per-App Daily Limits : Configure custom limits (5–240 min) via preset chips or slider, with daily repeat toggle and 80% threshold warning notification.
03
System Overlay Alerts : When a limit is exceeded, a full-screen overlay (running in a separate Flutter isolate) appears on top of any app — with snooze (15 min) and close options.
04
Persistent Background Service : Foreground service with notification that polls every 5 seconds, checks limits, triggers alerts, and survives app kills via Boot Receiver + WorkManager watchdog.
05
Analytics Dashboard : Animated usage gauge ring, weekly trend line chart with touch tooltips, most-used apps ranking, active limits progress bars, and category distribution breakdown.
06
Focus Mode : Toggle to suppress limit alerts and lock in focus, tracked as part of daily device stats.
07
Battery Optimization Exemption : Requests the system to exclude StayOnTrack from battery optimization so the background service persists.
