I am a kindergarten teacher and I love using this app with my students. What I consider one of the best features of this app is that I was able to customize it. At our school we use the Phonics Plus program which is an offshoot of The Spalding method. I was able to record the various sounds for each of the letters. For example, we teach that the letter ""Aa" has three sounds; "a" as in apple, "a" as in angel, and "a" as in the middle of ball.
The developer was wonderful to work with too. After I recorded the sounds on one of our I pad's in school, I was dreading having to do it for all the sets we use. In about two weeks time, the developer had my problem solved. I can save the recordings! When I sync the other iPads, it synced my recording too. Also, because I like this app so much, I recommended it to a parent for her child to practice. I was able to go to the settings of the app and email the recording to the parent. Now my student can practice phonics at school and at home!
