Very succesful campaign for Miles and More supported by native mobile apps called Xmas Shaker.
Like a Christmas Advent Calendar, you can win prizes daily just by shaking the phone. If you like the prize you can take it, otherwise you can shake it off and shake again.
The app has very nice christmas feeling through animations and sounds. Please have a look at the video.
I was involved in the complete developement of the iOS app.
Very pleased to announce that the Xmas Shaker won the Silver prize at "Deutscher Dialogmarketing Preis" for the great mobile campaign success it achieved.
