Convert Android app to iOS app?

I am wondering if there is any way to take my DAB app for Android and convert it to iOS for use on an iPhone?
I don’t have an iPhone or Mac available to me to help me build it, so I need someone else to help.

Sorry I went on vacation when you asked this and only now just saw it was unanswered.

You need an iOS machine to make a iOS app. You also need a developer account that costs money by the year. I have heard of people without a Mac paying for a virtual Mac to do their building on. It is not a trivial set up so is not easy especially if you don’t know the OS.
