That said, the fluid animations in Bike look great, and the video was very slick! Nice work.
My job frequently has me switching between different desktop operating systems and mobile, so for me a simple clear text approach works the best, and org-mode and Markdown has that nailed down.
So for now my tools are limited to Sublime Text on the desktop (with the OrgExtended plugin), Obsidian for my markdown notes (though sublime/vs code would work just as well), and BeOrg/PlainOrg on the iOS side of things, with simple file synchronization to keep files synchronized across platforms.
Ironically, TaskPaper was the tool that got me started on the cleartext approach (also written by the author of Bike).
OrgMode relies on emacs, which is not exactly in the same class of software that this is. This is "one thing well" stuff. Emacs and OrgMode are pretty much the other side of the continuum.
