Preflop+ is THE best app to improve as a poker player. GTO preflop charts pre-loaded (no internet connection required) to make +EV shove, calls and rejams based on Nash equilibrium.

Matt Berkey, High Stakes Cash Game Player and Founder of Solve For Why Academy says "Preflop+ is a great tool. It takes all the Nash Charts and distills them at your fingertips. It is far better than other apps as it displays EV of what each hand will be earning."

Lara Eisenberg, WSOP Bracelet winner, says "Preflop+ is a fantastic app for poker training. I find it particularly useful for drilling pot odds and equity which is something I haven’t found with any other app on the market. I use the app every single day to improve my ability to quickly calculate pot odds/equity situations which is invaluable to be able to do quickly, especially in the live setting."

Unlike many popular solutions, we present you with the exact EV of all the hole cards as a chart so you are equipped with making your own decision. This will help you make better decisions such as avoiding marginal spots when you have clear edge over the field. And also help you take any +EV spots when the field is pretty tough knowing the exact EV of your holdings.

Now you can create your ranges and view them on the go. Create ranges OPEN, CALL, 3-BET, 4-BET and more! Beautiful Chart overlays lets you see relevant actions in one chart.

The app also has the fastest and most accurate equity calculator for all streets - Preflop, flop, turn and river.

What’s New

Version 17.4

Added 200bb as one of the default stack sizes available in the 'My Ranges' module. As deep stacks becoming more common these days, this makes much more sense as available as a default option and not have to add them manually.

Great Study Tool!

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.

Lots of potential, still buggy

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:

If 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:

If you want to improve

This was exactly what I was looking for. I have tried several other apps that have been recommended to me, but many of them are not user friendly or don’t offer as many training options as this app does. I tested the app out on the initial trial and I am very satisfied and will subscribe. If you want to improve your game, this is one of the tools that you can add to your study regimen to be the player you strive to be.

Developer Response ,

Thank you for the kind words. Good luck at the tables!
