I really dig the #nextcloud #gpxpod app. The charts is a hidden gem, really - select 'details' in the file hamburger menu to see the sidebar. The track is yesterdays #sailing trip rounding Bjørnø, which happens to be the course for our local season racing start race (on may 4th). The funny uturn east of Svelmø was the wind turning - all close hauled on port tack :o
The peaks in the speed graph is due to the phone being in my pocket while walking on deck, I would love to have a script to get rid of them - easies way is probably to just delete the points causing them.
What is missing from gpxpod is the ability to select a part of a track and display data for that, and better waypoint support (not visible here), and overlay tiles so I can display the openseamap marks layer. And editing, like in gpx.studo. And ...
But it is still very nice to be able to view my tracks this way!
