RunCline provides incline information entered manually in the app and transmits it automatically over Bluetooth. Alternatively, it can read incline directly from your smart treadmill. It will also connect to an external foot pod and/or heart rate monitor and re-transmit the collected metrics over Bluetooth. What's the purpose? You can pair the phone or tablet running RunCline with Zwift and get incline, power, speed, cadence and heart rate. RunCline will also display all metrics on screen for you to view during your running. What's even better? Some smart-er treadmills can also be controlled by RunCline to make them track incline from Zwift on PC or Mac. RunCline can also pair with the Apple Watch to get heart rate and display some running metrics. The heart rate feature is using the HealthKit to transmit live heart rate values to RunCline and store them in Apple Health. Requirements: You need to pair a Bluetooth compliant foot pod and/or supported smart treadmill to RunCline to use the app. Otherwise, you can select the VirtualPod in the list of Foot Pods to use RunCline as a source of speed and incline for Zwift.
