I was excited to find this app to help my 4 year old daughter read notes better. She plays the piano and is beginning to read notes, but isn't fluent yet, so I thought this app might help. (She reads on a 3rd grade level, so I think she is capable of learning how to read notes.) Most kid apps we have are encouraging and use positive reinforcement. If you miss a question, you are encouraged to try again, and when you get it right, there's some sort of positive reinforcement. However, in this app, if you answer incorrectly, you hear "boo" sounds and unless you get all questions right, you lose and a sad tune is played. It's not encouraging at all and makes her not want to try again. If this was fixed, it would be a great app. But not as is.
