It used the same Bluetooth communications protocols as expensive running footpods. You choose your preferred Speed Input: 1 - Select the speed your treadmill is moving on the app and this is transmitted via bluetooth to your receiver. (This is my personal recommendation) 2 - Attach the iPhone security to yourself and run. The iPhone's motion sensor will estimate your speed and transmit this to your bluetooth receiver. ****** iPhone 5S and above. ***** (fully dependant on accuracy of iPhone) *****THIS OPTION WILL BE DISCONTINUED IN FUTURE VERSIONS, PLEASE RELY ON TREADMILL MODE OR WATCH MODE 3 - Use your phone in combination with your Apple Watch. The Watch will send Speed, Cadence and Heart Rate via your phone and transmit these to your bluetooth receiver. (Watch workouts can be saved as part of your daily activity rings) (fully dependant on accuracy of Watch) *New Feature :you can control the speed manually using the crown, simply tap the digital speed to enable/disable. Notes: • TSS Watch Module - requires an Apple Watch to calculate Heart Rate, Cadence and Speed data. • TSS Watch Module integrates with the Health App on your iPhone to contribute to your Activity Rings. It will request permission to access the relevant data types associated with a workout. *Connection to MAC Requires BLE 4.0 - The Mac mini , MacBook Air were both updated with Bluetooth 4.0 support in 2011. The MacBook Pro Mac 2012. The Mac Pro in December 2013. ## Rankings - #263,841 — Overall ## Review summary The app is praised as a low-cost, easy bridge to Zwift with broad treadmill compatibility and quick pairing, helping users run on Zwift and even aiding mobility‑impaired users.
