Im a huge fan of learning apps for my toddler.
The game has adorable, with little lightning bugs that make a teeny purr-type sound when you "collect" each one as you trace your finger across the shape. The App tells you "This is the octagon, trace the circle and collect fireflies". I love that it tells the child the shape, which is especially helpful for the little preschoolers that are still learning shape recognition. However, please note, tracing the shape can be a little difficult to do for a 3-year old on an iPhone due to the size, so I highly recommend a larger tablet for the tracing apps, for mamas of younger preschoolers.
One neat thing is that if you have multiple kiddos that play the apps, you are able to enter their "Parent Zone" and create different profiles for each child using the game. This is especially beneficial for therapists like myself that might let patients use the apps for reinforcement during therapy. Youre able to view their progress, so it can show you where theyre sitting for each of the workbooks in the App. I love that Kids Academy is interactive, has a pleasant (read: not creepy) voice, and cheery background nature sounds with music. Youre able to select male or female voice overs, take away nature sounds for those kiddos that might have sensory issues with those kinds of noises, and are able to turn off the background music, as well.
I think this app is great that it teaches the proper direction of shape formation, but there is more than one way to make a triangle. Also, when there are multiple errors, there is a cheery voice that is meant to encourage, but it says "This is easy!", which can be extremely frustrating to a child who is having a difficult time. "Good Job", or "Keep Trying!" or even, "You almost did it!" would be more encouraging.
