For my personal data, I use GPSLogger; it is fine and does what it is supposed to do. I never look at it, so I do not need any fancy features, and the main selling point for me is that it also saves the GPS data on my phone so that, in case of an error, I can still pull it and import it. OwnTracks also works fine; if you have multiple users, one benefit could be that Reitti can send the location of your other users back to OwnTracks so you can see their locations directly in the app. Finally, if you want more features, there is also Colota, which is the most modern of them all.
