Companion app Help needed

Can anyone help me in building a companion app for any game ??

I can, with anything you will need. But you need to provide more details for me and the others to help you about what you need.

First of all, what do you mean by a companion app?

And as Makeroid is not available at the moment, with which builder are you going to create your app? or are you waiting for the Makeroid Reborn?
