Device Watch is an Android device monitor with home-screen widgets, per-app usage insights and an interactive screensaver for charging or docked use. It works fully offline: the app has no internet permission, and every number is real data read from Android and kernel sources.
The widgets show battery, memory, CPU, storage, Wi-Fi, mobile network, data usage, uptime and screen time. The app adds a screen-time chart, top data users, a last-opened list, device details, a 62-day usage history, 14 days of battery history and charging sessions, CSV and HTML exports and optional alerts. Shizuku or root, both off by default, unlock extended statistics.
The screensaver shows a large clock, the next alarm, charging power and unread notification icons. In English and Finnish; also on F-Droid and Aptoide.
