ADHD Treatment by Eytan Shleizer is designed for children with Attention Deficit Hyperactivity Disorder (ADHD). This app is all about waiting until the right moment. On Level 1, a green square appears and you have to wait for it to change colors before you press the button with a checkmark. If you wait until it changes the red, you can continue with the game. The square will continue to change colors until you have clicked the checkmark ten times. Then, on Level 2, the game changes slightly and you have to wait until the shape changes location on the screen. On Level 3, you click the checkmark every time any change occurs. The shape, color, or location can change, or any combination of the three. On Level 4, you tap the checkmark every time a change occurs, except for when it is red. There are more levels but I haven’t gotten to them yet! It costs $9.99 to download and there are no in-app purchases. It is compatible with the iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation), and iPad.
