Many elite poker players study game theory to ensure they make the best decisions at the table. Crunching the numbers using advanced computer simulations, their aim is to play as close to ‘game theory optimal’ (GTO) as possible.

DTO Poker brings the results of thousands of hours of this GTO study, from some of the world’s best poker players, straight to your phone!

Learn to play optimal poker by:
• Diving into specific MTT and SNG situations and playing hand after hand, testing your decision-making skills vs. mathematically proven GTO solutions
• Setting up the precise scenario you want to practise, adjusting variables like stack sizes and position
• Receiving a grade for every hand you play; instant feedback shows how close your decisions are to GTO, and exactly where you can improve

With over 100,000,000 MTT and SNG scenarios pre-solved and ready to play there is no need to spend money on expensive poker coaching.

Conceived and developed by professional poker players, DTO Poker offers a unique, effective, fun way to train through play.

Now the benefits of advanced poker study are available to everyone, whether you’re an amateur playing a few hands to hone your instincts for your home game, or a professional exploring the deeper concepts of GTO.

DTO is world-class training software

It’s hard to put into words what DTO has done for my game in such a short time. Without rambling too much, DTO does one thing very well: it teaches you HOW to win. It might show you things don’t make sense right away or things you don’t agree with but ultimately it is showing you the most optimal way to proceed in thousands of post-flop scenarios. If you’re not getting value out of DTO within 30 days then you’re misusing the app, period. Highly recommend for poker players of ANY skill level. Whether you understand GTO play or not. It can only help your game so why not use it?

Unbelievable App must have for active phone users

A wonderful app in and of its own right. Very clean and intuitive. Beyond that it’s really the first gto solver you can use on a phone. If you prefer phones over computers for studying this is an unavoidable purchase.

Need more deep stack spots and explanations

Good app in concept, things I really need
1. Appears to be constructed more for tournament play and stack depths, would be preferred to have more 100bb 200bb spots (very limited right now in deep stack) to practice
2. Like other reviews, some explanations (this can be a lot of work but perhaps you can create software component that detects your hand and flop (e.g. gut shot on wet board and you have no flush blockers) as you can have maybe auto generated text that could guide user to figure out the best line
3. Please comment in app description about accuracy of solutions; how do they compare to PIO? If I put your ranges and situation in pio will I get same result?

Developer Response ,

Hi there,
thanks for your feedback.
1) Those deep stack spots are coming. You’re correct that the primary focus off the app is tournament play. We’re probably not going to launch any 200bb spots though.
2) This is sadly impossible. Oversimplifications such as your example would imply that GTO Poker is easy. It’s not. That’s why we have a dedicated discord to discuss hands.
We also have #DTOConcepts on our socials.
3)Our sims are solved at a very high accuracy. Assuming you run your sims correctly your results should get reasonably close to ours
