Leave the exercise studio behind and run your fitness classes in any location. Use the FitFones Instructor app by Wireless Fitness and stream your voice and a playlist live, in real time. Your class participants just need an iPhone, the app and their own headphones to listen in and be part of your class, like a silent disco with added fitness. Compatible with any exercise class, just select a track on your phone and when you press play and start speaking, your voice and music are streamed live to any phones with the app nearby.
