I’ve just found Syncthing and I’m blown away by this app. So, I’m interested if any of my other apps can be replaced by foss equivalents that can be synced.

My first suggestion is Obsidian - which, at first I had problems syncing with paid solutions, but syncs flawlessly with Syncthing.

Does anyone have any more suggestions? Ideally looking to sync between android devices, but any info is much appreciated.

Update : many thanks for all the suggestions - some good ones. Hopefully we can keep adding the ones we find that can be synced from local folders.
