If this improves the Apple Pencil experience this could be a great improvement. Would be nice if this could be tied into Obsidian to replace the web based version somehow.
The browser based ink/drawing support on iOS devices is pretty bad (and hard to fix since Apple doesn’t expose the ink APIs in JS from my understanding).
Now is a great time to be replacing web apps everywhere with native tools that are memory efficient, private, and highly responsive.
There's an excalidraw plugin for obsidian, really nice.
