Found an app that is free for a limited time? Give us the heads up here.
It would be useful to let us know which device it's for, but don't be shy about giving the information.
To get the ball rolling here is ShortWave, for the Mac. No idea how much it usually goes for, but it's free today. It has a searchable list of radio stations available for streaming to the Mac. Right now I'm listening to The Police on Antenne Bayern.
Please note the intention of this thread is to give information about existing paid apps that are free for a limited time. It is not for announcing apps (we have threads for that), nor for giving info about lite versions or other normally free apps.
