Finding Math Recognition

This is a purchased “in-app” feature you purchased within Notability FOR Notability.

There is NO extra app involved.

The Math Recognition feature is another paid feature added to Notability, itself.

That feature works within the Notability app, itself.

Try this within Notability.

Best of Luck to You!
