If you buy the app you support NC-17 in to the future to make more nice cool products. Many thanks for this! Manly the app is a cycle computer with ANT+ and BLE4.0 functions. We did not program the Sensor paring the app will find all sensor next to the phone. If you want to change the sensor you need to reinstall the app. 2014 the Bosch CanBus is added to the app but you need the NC-17 Bosch adapter to make it work. Any Help on the app side is welcome we are focus on the Bike Hardware. This is a wonderful time create new ideas around the Bike. Stay in touch so see what is coming up next. Thanks
