Wireless Fitness is an app that allows you to run you music-based fitness classes outdoors without the need for a fitness studio or any stereoequipment. The app achieves this by syncing the content and instructions from your phone and microphone to the phones, and ultimately wireless headsets, of the participants of the class.
The app, which is currently available only for iOS, lets you create and schedule classes, set price points, monitor attendance, view financial reports and contact your mailing list all from within the app. You also get the ability to automatically bill students for classes attended.
The app is currently free for use but promises a premium version soon.
