DO NOT use this app if you want to avoid future learning to read problems! While this app is cute and fun, it does NOT teach correct articulation of the phonemes (sounds). As a special education teacher of 20 years, I cant tell you enough how difficult this is to correct once learned incorrectly. I contacted the company and offered to help put in the correct sounds and was told they werent interested in accuracy of the phonemes, all they wanted was a fun game to teach letters and words and if I didnt like that, like the other speech language therapists and teachers that had contacted them, then not to use it. Very disappointed that they would knowingly cause children to develop reading difficulties! Please avoid the app at all cost!
