@doctorwindows The app I'm working on wouldn't cost anything as I'm just providing a way to access your existing Aworka account on your mobile. It would be too risky to run your business solely from your phone as they are too easy to lose or damage, so there would always need to be communication with a cloud-based system (like mine), or synchronisation with a desktop PC app (like George or WCP) to ensure your data is backed up.
