@twers fixed, this will be in 2.1.3, the next App Store update. The app is iPhone-only, so iPadOS runs it in that zoomed compatibility window, and since it only declared portrait it never rotated at all. From 2.1.3 it rotates to landscape on iPad. It's still the scaled iPhone layout though, not a native iPad UI. A proper iPad version is a much bigger job, the keyboard itself would need its own iPad layouts, and I plan to open that together with iPhone Duo support.
