Is Unity a valid option for non-gaming app development on iOS?

Hello, I am planning to start programming an app for iOS. The problem is that I don't have a Mac and am too poor to buy one. A "hackintosh" is also out of the question at the moment. Since I heard that you can also create non-gaming apps for iOS with Unity, I wanted to ask whether it makes any sense at all or whether it is far worse then the already named options.
Thanks alot.
