I tried this app on my Fenix 6 pro for the first time yesterday. After a few 1/2 mile runs I did my first jump - recorded 4m height (winds were 11-12 knots on flat water and I was on my 21m Speed 5). During my 1-1/2 hour session it recorded only 8 jumps whereas I jump at least once on each run. I'm not sure if the jumps were too "stationary". I think that several were over 4m high.
So I am wondering what the criteria for stationary is? Is it less than 5m, 10m? May have made a difference in recording my jumps. Also, does the app use the full GPS (GPS +GLONASS) and data recording every second? Also, my jumps are not "explosive" in light winds so the accelerometer may not be triggered for those jumps and with my Speed 5 my landings are very light so that may be a factor as well.
After I synced with Garmin Connect the app showed the highest jump and the longest jump. It also showed the highest jump record and longest jump record which are apparently switched as the highest jump record showed 26.3m which was the longest jump distance. I've never jumped over 20m, perhaps in my dreams maybe.
Also, as previously mentioned it would be nice to show the time of day and to have the jump data stay on the watch face longer after a jump.
