I have tried others but this is the best. I had a recent problem when I upgraded to a new iPhone and sent an email to support. Within a very short period of time they responded and solved the problem – superb customer service. Highly recommend this app.

Works well on the HTC Wildfire. I like it because it works, just using voice instructions with the screen off or with other apps in the foreground. It has a host of options to adjust for individual requirements.
