Lock your screen instantly with a double tap.
About this app
TapLock is a minimalist utility that lets you lock your screen with a double tap — perfect for one-handed use and quick screen locking without reaching for the power button.
Create a resizable, transparent home screen widget and double-tap it to lock your phone instantly. TapLock also offers several other ways to lock:
* Home screen widget (resizable, with optional icon and multiple styles) * Quick Settings tile * Draggable floating button * Double-tap the status bar * Double-tap the lock screen, edges, or corners
Additional features:
* Adjustable double-tap timeout and lock delay * Optional vibration feedback with light, medium, and strong patterns * Per-app exclusions so taps are ignored in apps you choose * Available in English and Spanish
TapLock uses Android's accessibility service to power off the screen. This permission is required for the app to function, and TapLock does not collect any personal information or track any other interaction you have with your device. The full source code is available for transparency.
Note: On devices with Android's Advanced Protection enabled, the system blocks all third-party accessibility services, so TapLock cannot lock the screen while Advanced Protection is turned on.

Launch the app from your home screen

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.ah.taplock is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for TapLock, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of TapLock, and a listing is removed when the evidence for it stops holding up.
