Such a cool app, wonderful practice, nice look, clean and isolates the skills involved. Recording capability is great. Big problem: the consonants are not phonetically pronounced. Each consonant sound adds an uh sound to the true consonant sound. If you phonetically spell each one the way the app demonstrates, each consonant would be bu, cu, du, etc. Seem like a minor flaw? Not to a teacher or a child first trying to master phonics! Also, this app needs to continue into early phonetic word building, with photos of 3 letter word phonetic objects (hat, bun, sit, dog, etc) like other apps do. This could be the dominant app for starting to learn to read, doesnt quite get there yet. I hope they fix the issues and expand it.
