-## Overview
+This project was archived on March 11, 2026. The functionality formerly provided by this app has been moved to the [BLE Tool Subapp](https://git.ktag.clubk.club/Software/Android-KTag-Apps/src/branch/main/subapp-bletool) of the new [KTag Apps](https://git.ktag.clubk.club/Software/Android-KTag-Apps).  All of the existing Android apps have been consolidated into the main KTag Apps repository to simplify maintenance and provide a single distribution for related functionality.
 
-This software is used primarily for testing the BLE interface to KTag Devices.
