I have no money to do it but I had thought of two Apps, one is as rj_montana said, with freerolls. The other one that had occurred to me is an interactive coach, but I insist, I can only contribute ideas about it (I have a few). Greetings from Buenos Aires.
Not sure if this already exists as i opted for a cheap hud long ago and still use. drive hud. But i always wanted an option that only shows the hand stats on hands between me and current villain not all hands that we were both at same table.
an app that somehow enrolls me into frerolls i have access to pw of already. I am always just a minute or two late because i was caught up in another game. Happens alot at cc freerolls at chico sites.
