Startup Idea: Cross-platform Poker Statistics Software

Startup idea to develop a cross-platform software that offers advanced statistical tools for poker players. The software should include features lacking in current tools, such as showing the equity of a hand versus a range of hands for both cash games and tournaments.

I am a poker player that makes use of various statistical tools to help me see tendencies in play. I have a problem finding good tools across devices and platforms. Some of the better software is Windows-only and it would be nice to have advanced tools on mobile devices and other operating systems. There are tools and apps that exist, but they lack the advanced features that are really necessary. The most important feature is showing equity of your hand versus a range of hands for a cash game (isolated event) versus a tournament (goals may overshadow value of current hand). Yes. I am aware of existing software but it is not always useful.
