It's been about a month since Tobii introduced their app for iDevices, Sono Flex, and it's been getting great reviews. Released on October 7th, Sono Flex is one of the first apps developed by a communication device manufacturer. I finally had a chance to try it today and found it to be extremely easy to customize. It has over 50 pre-made context vocabularies, and customization is very user friendly. It's available for PCs as well as dedicated speech devices running Tobii Communicator.
