Local-first here means starting with a local data model that syncs to the cloud from the start, rather than an app that only works online.
(I know you said not web apps, but it does have a desktop version)
So Photoshop, Blender, etc. -- these are not apps that store their data in the cloud. They're using filesystems. There's no sync. They're not local-first, they're just local.
But the Apple apps -- Notes, Music, Calendar -- they are very much local-first. Their source of truth is in iCloud when you activate that, but they fully work offline as well and then sync once there's a connection. This is completely different from e.g. Photoshop.
Ones that you have to pay for directly?
Aside from game devs it's hard for me to think of who the major players are in that space any more. And now even when the game has a single-player mode it seems to demand an Internet connection, whether for DRM reasons, "anti-cheat" (why do you care?), updates etc.
But one enables continual revenues streams and the other succumbed to extremely rampant piracy in the app space. As such, even many games on mobile are service games rather than a local single player game.
