GPS should work as a source of current pace. The app allows you to choose which of Apple's systems provide the instantaneous speed: the Pedometer system, the GPS system or the Health system.Why didn’t GPS not work? I put all settings to gps and test but no current pace. Why do I need such weird settings like Pedometer or Health.
My Garmin Fenix 3 has only gps and can display the current pace why can not Apple?
Interestingly the documentation for the current speed from the GPS system no longer says that it is unreliable, so it may be ok now. I haven't looked at it in years but it previously said that it was unreliable but now it doesn't. It also has a speed accuracy value, which is interesting. I will have to investigate that at some time.
So you are not seeing a value even when you have set the source of current pace to GPS? Are you sure that you have set the source of the current pace to GPS and not the source of the distance and average pace?
