The release date is not yet set, and the app is still in beta. However - we'll be showing of the current version this week at Qt Developer Days in Munich. If you want to see it in action, come talk to us at devdays - we'll be wearing our Cutehacks t-shirts.
Also, the app impressed the Qt guys so much they asked if they could include it on their demo pavilion. Who are we to say no? So on their demo pavilion in Munich they will have some N8s with the beta installed. Press the YR icon and off you go.
