App has great potential. What is designed is supposed to help greatly even advanced poker players.
However, bugs limit usability to a point where app ends up becoming shallow. For example, when defining and customizing ranges in iOS, it is not possible to add different actions (open, open shove, limp, etc...). It is also not possible to add frequencies to different combos.I tried to contact the company by email to see how to sort this but got no answer...
Hope they will correct the bugs and PreflopPokerGTONashCharts will become all that it can be.
Update: after contacts with the developer, I can indeed add frequencies, but different actions are limited to the paid version.
All in all, this seems like a great app, not super user friendly and lacking better instructions, but super powerful. As it is, the free version is a sample of what PreflopPokerGTONashCharts is, like a trailer to a movie, but not very useful.
Paid version is probably worth depending on your buy in levels, for me at this time it is too expensive to justify the returns I would get.
Wish the developer luck and updated to 4 star which is fair for the free version, in my view.
