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:

* Home-screen widget: battery, memory, CPU, storage, Wi-Fi, mobile network, data usage, uptime, today's screen time and last update time
* Data counters per calendar day or per one-month billing cycle with a configurable start day
* Tabbed dashboard: Overview (live battery ring, usage counters, system meters), Apps (usage insights), Device (hardware, SIM and Wi-Fi 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: screen time, unlocks, filtered notification count, restarts and charging sessions
* 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, charging power in watts, battery-tinted background, optional night dimming and a battery-full notification

All statistics stay on the device. Nothing is uploaded anywhere.
