ZoomIt is a beloved Sysinternals utility from the Windows world (with a recent macOS release). Scribbble is a Mac-first app focused purely on drawing on the screen, with a modern UI.
ZoomIt is a free annotation, zoom and break-timer utility from Microsoft Sysinternals. It originated on Windows and Microsoft has since released a macOS build. Its strength is its zero-friction hotkeys and the integrated zoom feature.

Yes — Microsoft has released a macOS build of ZoomIt. Scribbble is an alternative built Mac-first, focused purely on drawing on the screen with a modern UI rather than the classic Sysinternals utility look.
No. Scribbble is focused exclusively on annotation. If screen zoom is critical to your workflow, ZoomIt or macOS's built-in Zoom accessibility feature may be a better fit.
