【實用工具app】KHSystem|最夯免費app-綠色工廠好玩App

Kingdom Hall System is application designed to be used on Jehovah’s Witnesses congregation halls.

This application is in under heavy development now and need some additional configuration to work. Feel free to contact me in order to get some support :)! I will publish more details on my homepage in a few days. I will also publish not only full source code of this application (GitHub) but also electrical schematics and firmware of additional interface.
