Ratings and Reviews
Awesome
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.
Mastering Basic Strategy! Small bugs need fixed
Absolutely love this app for basic strategy and will probably purchase it once these bugs are fixed. I download it yesterday and the app doesn’t fill the screen it cuts off on each side on IPhone. This is on every screen, so my highest score I can’t see, except when I earned it. My % correct I can’t see. Also the weakest hands screen is great to understand where you are struggling but it’s not 100% accurate with its calculations, but still after a 1000 hands it has done pretty well. My highest score so far is 169. Something I would love to see in the next update is your score after each run. For me to know how many I got correct I have to keep count, and since my high score is so high it’s hard to know how close I came to beating it, if I don’t have a constant this is how many you got correct in a row. *Please add this functionality, it would greatly improve the app*
Thanks for a great app thus far! Keep it up!
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
