ActivityLog2

I tried GadgetBridge because it cannot sync the activity files (.fit and/or .gpx) so I still had to plug the watch into a computer to keep the actual data. So I ended installing ActivityLog2[0] to do something with the files I had to have on desktop and GadgetBridge was of little use because relying on GadgetBridge without actually syncing the files might make me forget about doing the backup to a device I control (GrapheneOS or a computer). As soon as GadgetBridge support syncing the files from the watch to the app (or any local folder on Android), I'll install it again and stop doing the manual backups over USB. Syncthing will do it automatically. [0] https://github.com/alex-hhh/ActivityLog2

Open source related application, for open source desktops like Linux (unfortunately not for open source Android/GrapheneOS currently), there's Alex Harsányi's ActivityLog2 (which is an impressive application in Racket): https://github.com/alex-hhh/ActivityLog2/wiki/Just-The-Scree... Incidentally, I'd love to have an open source, privacy-respecting nutrition tracker that works on open source desktops. (I find my laptop much, much faster than phone for recording this data, at least in the ad hoc way I'm doing it, including things like weights of every ingredient that goes into a dish.)

I use ActivityLog2 which also reads FIT files. https://github.com/alex-hhh/ActivityLog2/releases

I've not seen it mentioned yet in the discussion, but my preferred open source tool for analysing Garmin FIT files is ActivityLog2[1]. Written in Racket, it provides some very nice analysis tools for cycling, running and swimming. Regularly updated and decent blog posts on different aspects by the author.

Don't dismiss Racket too soon, I would say. The developer of ActivityLog2 has been doing a lot to integrate charts and graphs into Racket GUI applications, and the program itself (https://github.com/alex-hhh/ActivityLog2) is a good showcase of that work. His blog is also worth a read (https://alex-hhh.github.io/index.html). Take a look!

One can still do cool things with racket/gui, though: https://github.com/alex-hhh/ActivityLog2
