Nick Bicanic, founder and CEO, and Andrew Wanliss-Orlebar, founder and head of product, at echoecho demonstrate the echoecho app and talk about development using Qt SDK. echoecho is a global location sharing system that enables people to find their friends anywhere in the world, then chat or arrange to meet. The company launched the app simultaneously on most major smartphone platforms. This gave Nick a unique opportunity to compare development environments: Nick found Qt SDK to be a ‘breath of fresh air’ and easy to use, noting that a working version of the app was created in just two weeks. Of the Qt tools and technology, Nick pays particular attention to the maps capability offered through Qt Mobility. This enabled him to add a fully functioning map to echoecho with only a few lines of code.
