DTO Poker App Testimonial Manig Löser

‘’I couldn’t recommend it more! DTO Poker is by far my favorite App of 2019. Using it will improve your Poker skillset more rapidly than any other program/ video course I’ve seen before and all that while you feel like you’re playing a game.’’

DTO Poker App Testimonial Simon Rønnow Pedersen

‘’I think it’s an awesome app. Very easy to be productive on the move. Surprised that it’s this addictive. Also find it very useful to work with when I’m doing exercise like powerwalk, cycling or just walking outside. Normally I hate to do this, but with DTO Poker time flies by!’’

Simon Rønnow Pedersen

DTO Poker App Testimonial Parker Talbot

‘’While I do regulary study by reviewing hand histories and running SIMS with friends, DTO Poker has become the easiest and most efficient way to study for me. I use it most days even if only for 30 minutes in bed. The improvements continue to make this app easily worth the monthly sub and I would definitely recommend to a friend.’’
