I had high hopes for this app. However, as soon as I heard the letter sounds pronounced, I saw Id have to delete it. There are no letter sounds that end with "uh". Its not /buhand/, for band; its /b/ /a/ /n/ /d/.
This is not an app I would use with my child at home or school to enhance reading. Shame, shame for not pronouncing the letter sounds correctly.
