Force rotate device or using iPad/iPhone app on MacBook

Hello, thank you very much for clicking on this question. :)

I’m using an app and on it you can type with the on screen iOS keyboard. However, the app only works in portrait mode so the keyboard is also in portrait.

I was wondering whether it’s possible to force rotate the keyboard or the app so that I can type with a landscape keyboard because I find that easier to use.

If it’s not possible, the other option I was thinking of is somehow transferring the app to my MacBook or emulating it or something similar so that I can type with my actual MacBook keyboard instead.

Please could someone let me know whether any of these options are possible or if there’s another option available. Thanks for reading! :)
