The app does not store the elevation in Apple's Health system. I assume they derive that from the GPS data in the workout route, which could be why it is less smooth.When digging into elevation data issues I found out, that the elevation graph from a direct export from WorkOutDoors looks different compared to an export from Apple Health.
For me it looks like WorkOutDoors is applying some smoothing for the elevation data where Apple Health is not.
That surprised me. I assumed that the elevation graph would look identical no matter if exported from WorkOutDoors or Apple Health.
Can you confirm that this is really what happens?
Please see attached screen shot where the same workout is imported into Garmin. One is directly from WorkoutDoors and the second one out of Apple Health using HealthFit.
Background is, that some apps where I import the workout data have issues with the "jagged" elevation data exported from Apple Health.
Btw. I’m using the Altimeter Data. Will give the GPS option a try and see if that makes a difference to the elevation data stored in apple health.
There are however issues in the current version when using the always on altimeter, so you may want to switch that off in the Other Settings section of the Settings tab in the iPhone app. These should be fixed in the next version.
