I had a look through the source code and I would seriously suggest nobody use this application, there doesn't seem to be anything malicious but it is very poorly designed. It is parsing the Antminer web interface rather than hooking into the cgminer API. Loading the HTML interface on the Antminer takes up excess processing power and should be avoided at all costs especially on S1 which runs a MIPS based control board. Using this application could very well cause instability and reduce your hash rate.
