You can’t choose between Android and iOS without taking Google Play and the App Store into account. They’re the largest mobile marketplaces on the planet, and they both have their strengths and weaknesses — especially when it comes to control.
Apple has strict App Store guidelines, and every title is tested by a human before being approved. In comparison, Google is happy to let most things fly — so long as it’s not offensive or harmful — which gives us access to things like emulators and file downloaders that aren’t available on other platforms.
But is “open” really better, and could Apple benefit from loosening its grip on the App Store?
