I relied very heavily on Day One until they dropped most of their local-hosting features. It was painful and I still haven't found any comparable alternative.
Wow, I didn't realize they did that... I've had Day One suggested to me many time and always resisted, I guess I'm glad I did. I don't know what I want as an alternative, though - I guess what would be ideal is something that is Desktop/Mobile, syncs markdown to a shared filesystem like Dropbox, and has lots of optional bells and whistles for cataloguing and organization that I wouldn't mind losing since I'd still have the actual content in markdown.
I tried. There isn’t one. Dyrii was decent. But it was abandoned. There’s Journey (with their cluttered and poor interface) but they’ve not been able to pull themselves out of Google’s sink-hole. Even after you login with Apple Login they ask you to add a Google Drive account to sync data.
So I literally just moved back to pen and paper. Something I had been doing since school (school school). I haven’t missed any journaling app since. But having one would be nice.
Same. I still use the old app on my iPhone. Syncing to Dropbox and iCloud no longer works. I periodically export to pdf as a backup. I have nine years of notes in that pdf.
At some point an iOS update is going fully break the app, but I'm still hanging on.
