josm VS Tasty-Planet-1-Level-Editor

I modified an open source GPX recording app called Trackbook to turn it into a 24/7 recorder, and I wrote about it here:

I have a few recent commits in my repository that I haven't put into a versioned APK yet though.

The output GPX files can be viewed on the PC with JOSM:

Here's a view in my editing-program (https://josm.openstreetmap.de/):

JOSM has quite convenient merge/split functions, making deletion and re-tracing unnecessary. I took care of the issue in https://www.openstreetmap.org/changeset/134052747

Record your track and upload it onto Open Street Map. That's the map service that Strava and Garmin utilize. You'll be able to add the trail for everyone to see regardless of the program as long as it uses OSM. JOSM is a really good program to edit OSM and here's a video to get you started on how to use it.

Great for preparing data for OSM, but JOSM is the only desktop editor for actually making contributions.

One that comes to my mind would be JOSM: https://josm.openstreetmap.de/

If you want to do more advanced editing, I would suggest JOSM. It is very powerfull and there is a huge list of plugins. You can do almost anything, but it runs on desktop devices.

You could also do all of this in OpenStreetMap or one of its open source editors like JOSM, then run a filter for tags of those features (probably something like “playfield” or “baseball”) in Overpass Turbo. One cool thing about this option is all your work would be visible and usable by the general public forever.

If you want to look at the structure of OSM, JOSM is a good desktop application and Vespucci for Android is the least awful option there. The wiki can tell you what the tags mean; here's more info on the route tag. You can find more info about the Overpass API that lets you run weird queries against the map here.
