Exactly what I was looking for. Weakest hands chart isn’t 100% accurate, there are certain hands I know I’ve seen that show up as a dash. Other than that this app is perfect. Wish more explanation was available in app but easy to find online. Final thought maybe make a mode that allows the hands to be played out and let you know if you make a mistake throughout the whole hand. I know that’s not what that app was intended to do but I think it could help. Once I split my 3s vs a 6 my hand isn’t over. I still have a lot of decisions to make that this app doesn’t necessarily 100% address. Love the app.

Overall a good tool, a little glitchy and occasionally gives the wrong strategy

I really like using this tool and it has helped me a lot. Unfortunately it can be pretty glitchy. If I use the app for more than 10-20 minutes, it normally freezes and I have to close it and reopen it. Also, there are times when it will say you used the wrong strategy but the explanation will contradict itself (i.e. the explanation says you made the right move but you’ll receive an “x” indicating you made the wrong call). There are also times when the “correct” answer given by the app during training does not match what is on the app’s strategy card (i.e. the strategy card will say that you should hit, but that answer will be counted wrong when you use it during training). The stats are either not accurate or just not updating from the first time I used the app. Overall, good tool. Just needs some fixes

The simplicity of this app is amazing and I can’t say enough good things about it! I’ve tried virtually every blackjack app there is and nothing compares to this UI. Other apps are too focused on teaching/hand analysis and are too slow to enjoy, but his app runs as fast as you can push it! If I could make two minor changes, I would add an ‘undo’ button because I hate when I accidentally fat finger the wrong action and ruin my streak, and I would bring back dark mode for the strategy table like the earlier version used.

Hi there and thanks for the kind words! We're glad the fast UI works for you. We appreciate your feedback and will definitely consider an Undo on mis‑taps and bringing back dark mode for the strategy table.

This is a great app to work on memorizing basic strategy. The year subscription isn’t awfully expensive and you can customize the basic strategy for the type of game you plan on playing. It’s simple. Shows you all of your stats and what your weakest hands are and gives you an explanation for every hand whether you get it right or wrong. I’m just beginning to learn basic strategy and this training app has helped me tremendously! Highly recommended!
