Good app
HealthKit integration is good way, it works good from iPhone. I don't know how I can connect rope directly to Apple Watch. iPhone workout data don't show heart rate data from Watch. Second app (SmartRope TV app) Is good idea, nice data preview during workout, but data are not exported to iPhone app and HealthKit (it is total fault), add server synchronisation or choice for use rope + iPhone + Apple TV app like display only.
