App for Creating My Own Ranges

I'm not sure what you want the App to do but if it simply is a card matrix picture, you can create one with Excel.

Here is an example of a matrix, which is part of the output of a program I wrote that creates the calling matrix based on a number of inputs. That requires some complicated programming

Is this not what FreeBetRange is for? (google it)

I'd like to have it as an app on my phone though. If I'm sitting live, I'd like to be able to reference it between hands.

I'm sure I could use my laptop to create some ranges and take pics and store them - but an app would be easier I'd think.

Please don't be that guy

I'm 100% that guy, and give zero F's about it. My goal there is to win money, not appease anyone else there.

When playing live, not being engaged with the table is a good way to not make money.

If your goal is to make money, then you will do that better by paying attention to what mistakes your opponents are making, rather than dicking about on your phone because you've forgotten which of two perfectly fine options your hudbot software prefers in a marginal decision and making yourself out to be a clown who doesn't want action

You can create, save, and pull up ranges in an app called Pkrcruncher. It's an equity calculator but it has good range v range functionality. You can also save ranges in Flopzilla. Probably RangeTrainerPro too, but I've never tried that one and I don't know if it is mobile friendly.

For me, Range manager is the best. Low price. Quick to build, edit range. Color themes are excellent.
