Device Watch is an Android device monitor with a home-screen widget, per-app usage insights and an interactive screensaver for charging or docked use. It works completely offline: the app has no internet permission, and every number is real data read from Android and kernel sources — when a value is not available with the permissions granted, the app shows a dash instead of a fabricated value.
Features:
* Resizable home-screen widget: battery, memory, CPU, storage, Wi-Fi, mobile network, data usage, uptime, today's screen time and last update time; compact 2×2 widget with data-period labels
* Data counters per calendar day or per one-month billing cycle with a configurable start day
* Tabbed dashboard: Home (live battery ring, usage counters, system meters and live network traffic), Apps (usage insights), Device (hardware, SIM, Wi-Fi, camera and audio details) and Settings
* Screen-time donut of your most-used apps, top data consumers and a last-opened list with per-app uninstall
* Usage counters with a private 62-day daily history kept on the device: app screen time, screen-on time, unlocks, filtered notification count, restarts, charging sessions and used storage
* Battery history and charging sessions for 14 days, with temperatures and charging rates
* Optional charge reminders, mobile-data quota warnings and alerts for a hot battery, low storage or fast battery drain
* CSV exports and a self-contained HTML report with charts, search and date filters
* On-device notification log with 7-day retention
* Since-charge view: elapsed time, battery drop, average drain and per-app screen time since the battery was last charged full or unplugged
* Interactive screensaver with a large clock, next alarm, icons of unread notifications, charging power in watts, battery-tinted background, optional night dimming and a battery-full notification
The app uploads nothing. Android backup carries settings only, excluding history, notification content and delivered-alert flags. You can choose to share CSV/HTML exports, including notification text, through another app.
