Device Watch アプリ 向け Android 説明
Device Watch
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, todays 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
- Optional extended access through Shizuku or root, off by default: the real CPU load, chip temperatures, graphics load, the batterys own wear figures, and Androids battery statistics since the last charge (drain with the screen on and off, each apps share, what kept the phone awake)
- 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.
