Hello

For a long time I have used google drive sheets in order to keep track of gym progress because it has columns and I can dedicate columns, colors, rows, etc for specific gym movements each week so I can keep track of progress, progressive overload correctly, and have a history of progress. ( Example: days | weight | push | bench::weight*sets/reps | etc)

I have been using libreofffice (and syncthing to back up to home server so I can later view on pc) to do this lately but the mobile app is … Hard to use for me. I also use obsidian to take general notes and lists but it is missing the dedicated columns I would like.

Is there other self hosted similar options for what I’m looking for specifically for mobile to PC backup.
