The Vivino app already exists for Android and iPhone, and we're now looking for a QT developer to bring it to Nokia devices as well.
The app is simple, seen from a native app perspective, as most of its logic resides in a large browser-element. The main task of the native app is to utilize the camera, resize the image and send it along with GPS coordinates to the Vivino server. Almost all the remaining aspects of the app are taken care of server-side with the web-content.
Specs are attached. Source-code for Android and/or iPhone app will be made available to winning bid. The live Android version can be seen if searching for "Vivino" in the Android Market.
