Get the most out of your WAHOO KICKR HEADWIND by controlling it from your phone. When you're suffering hard during an intense workout, the last thing you want to do is search for an app on your phone, select the device, and set the right mode to adjust the speed. You want to tap on the lock/home screen and go straight to the app and set a new fan speed. That's exactly what TurboLance is for. Quick access and easy control. Fast open the app through a widget and let you blow away. Please note that you will need a KICKR HEADWIND. Without this device, the app will not do anything useful for you.
