I have been working with beta versions of FoldNotes (https://foldnotes.io and am quite impressed. FoldNotes is native Swift apps on Mac and iOS with iCloud sync.

The developer (who is quite responsive) describes it as Markdown notes that fold.

Daily Notes, Queries, Database views, Graphs; they are all there. He says he built the app for his personal needs and it has been a daily driver for over 2 years. Now he is building it up for public consumption, and it is a nice environment to work in.

I have migrated my work from Obsidian to FoldNotes. I had Obsidian built to meet my needs but the key word there is "built." I am a writer and worker, not a builder. I seek to get work done (difficult with my CRIMPing obsession, but possible.) FoldNotes grabbed for its native environment, and as I work with it I become more and more impressed with the capabilities.

One really neat trick is, on iOS, native Bike files can be edited in place, meaning you can have an iPad/iPhone Bike file editor today. Edit the file, changes are made to the actual Bike file, not a copy (that is the definition of Edit in Place.)
