Great app, some tips for improvement

Overall, this app is great for training from beginner to expert. Some things it needs to improve:
The card counting slider is not always accurate, or not sensitive enough. Sometimes it locks in the wrong numbers even though I had the correct count. Also, when the count is highly positive or highly negative, you lose points because if how long it takes to slide the counter, which is not an accurate assessment of your skill.
I also agree with others that it would be great to incorporate training for Basic Strategy in the app.
Another frustration is that the app often fails to register your high scores when showing your rank on the Leaders Board. It still uses old scores youve already surpassed.
Great program overall, definitely worth the purchase, but resolve these issues and youll get 5 stars from me.
