We are working on our thesis project, it's actually a mobile POS system. I understand that the sales transaction should be in landscape due to it's complexity. The screen is divided into two, right side is for the inventory and left side is for computing the sale.
Our app is not limited to that, we also allow the user to add inventory, manage settings, etc. Like a regular app.
My question is, should I set my app's orientation to landscape? All of the activity?
Is it ethical for a mobile application to be always in landscape mode?
