Decent app with room for improvement

I like the app it’s design and the tutorials. It’s nicely done and the pricing is fair for what you get. However for me to use the app it’s still missing one feature so I would enjoy using it more. Currently there are only the theoretical basics in separate tutorials which is good. What I am missing is a Casino practicemode. A mode where you start with some dollars and you can bring your knowledge to practice. This could even be splinted into different difficulties with deck counts, different player amounts and for real world scenarios with the deck counts casinos use and alterin player amounts during rounds.
