I've found that ios is a lot worse regarding fragmentation than Android. While Android requires a bit more legwork at the beginning, once you have written the app it will generally keep working on most devices. There aren't too many changes in new Android versions that break things. iOS however is a horrendous mess. Every year or two they overhaul their layout system (contentScalingFactor, then auto-layout, and other things). Also, each time a new version of iOS comes out you need to work around various bugs/changes and you end up tweaking/hacking your code to get it working on all devices. I've just spent an entire day getting one of our apps working on the ipad in iOS 7, and another half day getting it working on iphone. It will require another day or two to get everything working perfectly, and then I'll have to recreate all the new icons, launch images, screenshots, etc.
