Timeline of evolution
From the first tests in 2012 to today, the idea has always been the same: to make working with PLCs easier and control them from a mobile device. The difficulty over time has been keeping up with the constant evolution of the libraries in use, the user interface and the operating system.
Dates come from the development log and may slightly precede release on the App Store.
