Quote- too high results compared to most of the other appsI think this goal has not been achieved
When I go out, I record with both Garmin and Locus, I use Locus for maps and as a backup, often after the activity I delete the track on Locus. But I noticed a notable difference between the difference in altitude calculated between the two. Thinking it was due to the separate GPS data recordings or the fact that I often forget to stop the Locus track in time, I didn't give it any importance.
But reading Graf Geo's post I checked better and the calculation of Locus makes me doubt.
So to avoid comparing tracks taken with different devices, I downloaded the GPX from Garmin and loaded it into Locus, updating the altitude.
Locus 998
Garmin 860
Strava 864
Strava uses the same data as Garmin and there is a small difference between Garmin and Strava due to the different algorithm used, but Locus is very far from these values.
@Menion if you need I'll send you the GPX and the Garmin and Strava links privately
