Simplenote survived the Moby Dick workout. It lags a little after paste, and hangs momentarily on redo. It may work better with more structured data. (I used the markdown file in the webapp; didn't test native/mobile versions.)
> - Data transparently moves across mobile, web, and desktop versions of your app
> - Your users can read and write data even when they're offline
> - Multiple users can collaborate with the same data at the same time
> Simperium persists your data for you in buckets... Every Simperium object is JSON data that is stored in a bucket.
> Simperium does some basic conflict resolution for you automatically... When two edits are made for the same field though, Simperium supports automatic resolution for strings (currently) and will merge the two edits together.
So https://www.simperium.com/overview/ might be a low-effort option to add syncing without managing your own server.
