Updated version is Completely wrong in terms of how to handle a pair of 9s. It says to always stand….which is incorrect. How could this get by you all? Very disappointed!!!

The app is crazy unlucky it doesn’t keeps giving you cards so you’re only playing the first card, the labels are european. I don’t like that to change rules you have to pay monthly and you can’t unlock it forever, except this little inconvenience it is a very good app

It feels like a guessing game and all the features are blocked behind a pay wall, if the app was gunna be unusable without payment should of just made the app cost money

Leider werden einige Sachen nicht richtig berechnet. ZB double bei 9. Außerdem sind die Wahrscheinlichchkeiten zwischen amerikanischem und Europäischen BJ falsch. Sehr schade. App ansonsten top.

absolutely love this app for memorizing basic strategy—it’s incredibly helpful and effective. My only minor gripe is a quirky bug that prevents the main screen from fully fitting my phone display. It’s a bit odd, and the majority of the text is cut off, but it doesn’t significantly impact usability. I can still access all the practice options, so it remains a very useful tool.

I think it’s a great app that teaches good strategy except for you can’t do pretty much everything without getting premium, which is really annoying.

“Become a Player” screen still pops up incessantly despite signing up for a subscription already (I even restarted the app)

Solid interface and really helpful trainer when you want to improve your understanding of basic strategy. I like the detailed feedback, could go even more into the “why” sometimes.
