The app is super useful. I was trying to find something to do some odds calculations, and was excited to find and learn from the Nash chart. Super helpful for getting a better understanding of your odds for pre-flop action, particularly heads up play. Definitely worth the subscription if you’re gonna continue learning and want to take deeper into specifics between hand odds against fluctuating player numbers. Super cool that they offer calculations for nine handed and six handed for no charge. Definitely recommend. Especially if you’re new to poker and want to quick way to learn key concepts for competitive play
Lots of potential, still buggy
Skhantom
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 the app 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 the app 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.
Developer Response
Hi, We did a quick video tutorial on how you can add different ranges with frequencies, overlay other actions to view all of them in a single chart, etc in our youtube channel: https://youtu.be/vf7XjJXm1LwIf email is an issue for reaching us out, we are on discord with an active community of app users from whom you can get support and ideas on how best to use the app. Here is the link to join: https://discord.gg/FtsBb4u
Great Study Tool!
SXracer199
I use this app nearly daily to review ranges and test myself. I love the drills to help range study so I can more easily commit them to memory. Highly recommend for anyone making the attempt to improve their game and better understand their preflop strategy. The ability to also classify different ranges based on stack depth is a huge plus. I will note it’s important to have established ranges for the desired stack depths as the app is merely a tool for you to input your own ranges for study purposes. There are example ranges available but you will need to define your own to maximize this app’s potential.
Fantastic app for training/memorizing ranges
MonsterNutzLOL
Review from Sept 2025. This app is a hidden gem, especially for inputting your own ranges! The pot odds and equity drills are great as well. Yes this was a very expensive buy for me, even with the deep discount. I’ve never paid this much for a phone app before. I took advantage of a deal they were running and got the lifetime subscription. No regrets! As I advance more I’ll probably take a look at their other apps, specifically their Post Flop app. I don’t regret my purchase. I hope the devs continue to refine and update this app in the future. Thanks!
