TapLock

TapLock is a minimalist Android utility designed to allow users to lock their device screens instantly through a double-tap gesture. This tool addresses the need for quick and convenient screen locking, especially for one-handed use or situations where reaching for the physical power button is impractical. It is suitable for users seeking a simple way to secure their phones without relying on hardware buttons.

The app provides multiple methods for locking the screen, including a resizable and transparent home screen widget that can be double-tapped, a Quick Settings tile, a draggable floating button, and options to double-tap the status bar, lock screen, or specific edges and corners of the display. TapLock offers customization options such as adjustable double-tap timeout and lock delay, as well as optional vibration feedback with selectable patterns (light, medium, or strong). Users can also set per-app exclusions, ensuring that taps are ignored within chosen applications. The interface is available in both English and Spanish.

TapLock operates by using Android's accessibility service to power off the screen. This permission is essential for its functionality, and the app explicitly states that it does not collect personal information or track user interactions beyond its core purpose. The source code is publicly available, providing transparency for users who wish to review its implementation. The app is distributed under the Apache License 2.0 and is authored by modelorona. It is important to note that on devices with Android's Advanced Protection enabled, TapLock cannot function due to system restrictions on third-party accessibility services.
