Editor's Overview

BuzzKill is a system application developed by Carlos Asmat, packaged as a single Android APK of version 1.0 weighing in at 9.19 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 9.19 MB, so it installs quickly even on modest connections.
This build is signed by "Carlos Asmat" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

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/.

Frequently Asked Questions

Is BuzzKill free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does BuzzKill require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is BuzzKill safe to install?
We link to the exact APK published by Carlos Asmat. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update BuzzKill?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
