About this app
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.
