I would like to develop a IOS/Android app to keep track of preflop stats such as VPIP, PFR, 3bet% etc. Basically for each hand, users can update preflop action by simply tapping the player's seat symbol to switch that player's action(fold, call or raise), then preflop stats will be updated accordingly.
The idea is very straightfoward but i find it useful to help players like me who sometimes not 100% focus on player types and miss out information during long session. And I don't see any poker tracker app has this function yet.
Do you guys find it helpful to have such app? more idea would be appreciated.
