Smart people like John Gruber of Daring Fireball seem to believe that Android development takes 3x as many developers as iOS. He believes it so strongly he mentions it again in another post about analysts who try to fit facts into a narrative.
Unlike John, we actually do Android development full time, and we have for many years. Weve made big apps, weve made small apps. Sorry to disappoint you John, but a talented Android developer works at roughly the same speed as a talented iOS one. They make the same apps, of the same complexity, in the same amount of time. Sure there are differences in platforms and API. Some things are quicker to do on iOS, others on Android. Long story short, theres not a lot of difference when it comes to development time.
