No portrait mode?

This 15C calculator app doesn’t appear to work in Portrait mode. It only displays in Landscape mode. I would have asked the developer if I missed a setting for this but he is only on Facebook and I’m not on Facebook.

Responsive Developer

The developer has a cool HP 15C and recently responded quickly when I used the contact feature on his HP 16 C, another cool app, to tell him that the HP 15C app was not downloading for my iPhone 11. He fixed things fast. Many thanks.
