There are four ways to use your Kinetic inRide and Smart or Smart Control trainers with Zwift.
The first option uses the free Zwift Mobile Link (ZML) app for Android and iOS mobile devices to send BLE signals to Zwift on your PC/Mac. The second option is for Mac users only, and allows for native BLE support. The third option uses the Zwift iOS app. The fourth option is the newest available and uses an Apple TV for direct BLE connection with Kinetic products.
