if you want cross-platform app with some / same powers —
i highly recommend exploring Excalidraw and tldraw + their integrations with Obsidian (closed source) and Logseq (open source).
Excalidraw became my fav sketching tool, whilst tldraw has stronger text on canvas options.
Obsidian and Logseq are second brain apps (wiki / zettelkasten / linked notes / pkm).
I believe logseq + tldraw will outperform everything in the longterm, but is wip as of today
