Hello and welcome, Vijay. I’m Dave, and the lead developer of Program O. I’m currently on holiday in England, so I’m not able to be online as much as I usually am, but I will be returning home on the 10th of April, and can assist you more at that time.
For now, though, I should point out that the only “app” required (or even possible at this point) is a web browser, such as Chrome or Firefox. All that is required to access your local install of Program O is to point your browser to localhost/path/to/your/program_o_install
That said, however, inorder to run Program O, you also need web server software (Apache HTTP server or equivalent) and a MySQL database server. It’s often much better to obtain remote web hosting somewhere that supports both PHP and MySQL databases, as there are far fewer things that you have to do manually in order to get things running.
Sadly, Program O does not support any interface other than what I described above at this time.
As I said earlier, I can provide more details once I get home, probably after a good rest, so figure on hearing more from me on the 11th of April.
