Lock

Lock is an Android system tool that provides a quick shortcut for locking the device screen. Its action is performed simply by launching the app. The software is intended for situations where opening the app is a convenient way to initiate the screen-lock function.

Lock was created for use with the FAST launcher, where it can be found by searching for lk. This search is useful because the app name contains both the letters l and k, allowing it to be isolated as the matching application. The product therefore fits a launcher-based workflow centered on opening a small, purpose-specific tool.

As an Android application in the System Tools category, Lock is focused on a basic device-control task rather than general application use. It is released under an open-source license, so its source-available licensing is part of how it is identified in the catalog. The combination of its narrow purpose and launcher access makes it a utility for users who want a direct screen-lock shortcut.

MirrorNest distributes the official build directly from its own storage. Before publishing, MirrorNest scans the mirrored build for malware. This distribution approach gives Android users a catalog copy of the official release while retaining the product’s open-source and system-tool classification.
