On the first page, for example, the app asks the child (both in text and narration) to "Spot the red dot." The app then presents the screen, pictured at top, and the child must find and press the red dot. Every time the app is restarted the dots are in different places in each game, so it's a different experience each time a child plays.
Spot the Dot is solid. It's well-done and the narration is very good...but $3.99 is too expensive for an app like this. The app just doesn't match up favorably with the best ebooks (One Rainy Day), which also teaches colors, or teaching apps (Teach Me: Toddler) at the same price or cheaper for the targeted age group. There is also Starfall Gingerbread which is more fun, works with colors and shapes, and costs just 99 cents.
A few simple additions to Spot The Dot, such as the app saying, "That's the pink dot!" when a child presses pink instead of red, would be very helpful.
Definitely try the free version to see if your child likes it, but I can't recommend at that price.
