Same, it’s one of the good things that I got from being on Reddit/Feddit.

iOS has Möbius Sync as a Syncthing client, but it is not free ( but only 5$ one time payment) if you want to sync folders from other apps like Syncthing. The option to sync other folders was introduced this year.

I am also using iOS with Möbius Sync and it is working quite well. The sync is not running all the time in the background due to iOS restrictions but it is running multiple times per day on my device.

The option to sync folders was only introduced this year. It costs about 5$ one time payment.

There will be many conversion tools for Joplin to other structures. So I guess the format is a non issue.

There is always a risk of collapse for lemmy. When you are in decline there can be negative feedback loops furthering the decline.
