Notability for MacOS in the UK

"Can we purchase the MacOS version Notability for our laptops?"

I only see Notability on the iOS App Store. I don't see it when I search on the macOS UK App Store. Contacting the developer (as linked to by the other poster) may provide more information.

Is Notability available in the AppStore for the UK?

If yes, what problem are you experiencing when attempting to purchase?

If no, contact the developer https://www.gingerlabs.com

In the US, Notability appears to be only for iPhone and iPad.
