Best app for 3 year old

My 3 year old son loves this "game". He has completed all of his letters on the first level and is excited to be on the next. I love how the letters (upper and lower case) and numbers are marked with stars once theyve been completed, my son can keep track of his own progress. Im enjoying how each has three activities, watching the letter drawn, tracing, then free hand with minimal guidance. Then there are more levels so theyre interested enough to do them again! This is a wonderful app!
