Mobile user acquisition network Taptica has released Appear Exchange, “a free mobile click-based cross promotion platform”.

The Exchange allows developers to promote other iOS and Android apps on their unused ad space, gaining credits that can be used for free ad placements for their own apps. Developers register their apps on the network and then create personalised promotional offers to drive targeted advertising campaigns.

"We recognise that the best way for app developers to grow their applications and generate revenue is if they work together. The Appear Exchange platform offers the mobile industry a place to do just that, regardless of their marketing budger," said Taptica CEO Sigal Bareket.

The platform is currently in beta form and users who sign up will start with 2,500 advertising credits to help them get their campaigns off the ground.
