Available now from the App Store in the UK. (Please get in touch if you would like this outside the UK as it would be quite possible to do that but I don't know that it is correct/suitable for other markets).
Phonics UK is a very simple application to help with the pronounciation of the phonemes as taught in school phonics in the UK.
It was only after attending the reading evening at my son's school that I realised that I had been getting some of the sounds wrong. For example 'r' is pronounced more like 'er' than 'ru'. This led me to believe that an app like this would be useful both to help me when assisting my son and also many other parents and children.
Make sure your iPad isn't silent and that the volume is suitable and then just touch the phoneme that you want to hear. It is that easy.
The short version is that Phonics UK does not collect personal information.
