I was recently selected by Kids Academy, through Sverve, to review their Preschool and Kindergarten Learning App. My 5 year old son was happy to oblige and enjoyed the activities and graphics. He was bummed when he quickly reached the limits of the FREE version of the app. From what I saw of the app, it was a good review of letters and numbers for someone his age. He will be entering kindergarten in the fall and this app covered things he has learned in preschool and at home. He thought the app was easy to use.
