This is a portable recording tool for decoration acceptance and tile quality inspection.
It has transformed the traditional method of "coin tapping sound" detection into a clear, traceable, and statistically significant digital file.
The construction party, supervisor, property management, and owner only need to lightly tap on the tiles with a coin. Based on the sound they hear, they can quickly input it into the app. The app will generate a visual tile grid map, hollowing ratio statistics, and sub project reports, helping you see at a glance which wall and brick need to be reworked.
