Endless abc

 Here is one of the best apps I have seen yet. When they touch individual letter it play sound letter makes phonetically.Once it in place it tell you letter.  Then one they have spelled word it say it has cute animation and explanation of the word.It is free to try but whole alphabet cost about $4 You can find it in both android and itunes click link to go to app

Once you touch letter it become animated. Moving around and making sound the letter would sound phonetically. Once letter is in place it says what letter actually is.

Once Word is spelled out it will become animated and act out meaning of the words.
