AutoDND

Automatically enable Do Not Disturb when selected apps are opened.

AutoDND is a lightweight, privacy-focused Android app that monitors which app is in the foreground and toggles Do Not Disturb mode accordingly. No analytics, no tracking, no internet required.

Features

• Per-app DND control — select any installed app to trigger DND when opened
• Three DND modes — Total Silence, Priority Only, or Alarms Only
• Persistent monitoring — foreground service survives screen off and app switching
• Boot resilience — automatically restarts after device reboot or app update
• DND flicker prevention — switching between two monitored apps keeps DND active
• Battery efficient — 1-second polling using UsageStatsManager events (no Accessibility Service)
• Material 3 UI — clean, native Android look following Google design guidelines
• Zero tracking — no analytics, no telemetry, no internet permission
