Err… Are you sure? You still need Xcode to compile the app. And I think you still need an Apple iOS developer account ($99) to even distribute an ad-hoc app due to iOS devices looking up a valid provisioning profile among other things.
I developed the same app for iOS and Android back in June 2012 using PhoneGap, so the development was pretty much the same for both platforms. However, distribution on Android was MUCH easier. iOS has a lot of hoops to jump through. But, once the app is live, we had WAY more issues with the different versions of Android running on a bajillion different devices, as opposed to iOS devices running basically the same.
After developing for both platforms, I just stick with developing little HTML web apps using jQuery Mobile and my own virtual server. It’s way easier and works just as well as a native app for all of my purposes.
A little story about developing those apps back in 2012. I bet my boss (the CEO of the company) that I could build both apps and have them on the app stores in 2 weeks. Two weeks later, he was purchasing a fairly decked-out MacBook Pro Retina laptop for me, since I had to use my personal laptop to develop and deploy the iOS app. Best bet I ever made!
