Install a recent and un-crippled version of BusyBox. BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.

BuzzKill
APK
BuzzKill powers your phone off when you stop using it at night, so notifications and the temptation to scroll cannot wake you up at 2am. You set a nightly kill zone (e.g. 23:00 to 07:00). Inside that window, BuzzKill watches for the screen to stay off for a configurable number of minutes, then triggers the system shutdown via an accessibility service. Outside the zone the app does nothing. To come back on in the morning, use your phone's built-in scheduled power-on (e.g. on OnePlus: Settings, Additional settings, Scheduled power on/off). BuzzKill cannot enable this for you, so an onboarding checklist reminds you. Features: - Single-screen, hardware-panel-styled UI. - Configurable kill zone, inactivity timeout, and a first-shutdown confirmation dialog. - Test trigger with a 10-second countdown that runs the shutdown sequence in dry-run mode, so you can verify it works without losing your work. - OEM-aware: power-dialog matching strings live in a per-OEM file, currently tuned for OnePlus (OxygenOS). Required permissions: - Accessibility service (the mechanism used to power off). - Disable battery optimization (otherwise OxygenOS kills the foreground service). - Notification permission (Android 13+, for the persistent kill-zone notification). Primary target device is the OnePlus 11 on OxygenOS. Adding support for other OEMs (Pixel, Samsung, Xiaomi) is a data-only change in app/src/main/kotlin/ca/asmat/buzzkill/oem/.
