We actually do have a lite version of our software for mobile. You can check it out by visiting the terminal via your mobile browser. The issue with having desktop, mobile and web applications is that you stretch out development across 3 different platforms. We're currently a small team and we'd rather make 1 strong platform that everyone can use than have 3 junk and buggy versions.
Thank you for answering.
I agree, it's better if you focus on web version and make it bug free, and maybe in future you can think of expanding.
There is potential for sure.
