Just a bit confused, but are you saying Android isn't open? All you have to do to install third party apps on Android is un-check one box in the settings, under security (allow installation of apps from unknown sources) and find your apps through whatever means you prefer to the app store. There are third party app stores, or you can just download and install from a web link. Definitely not comparable to iOS.
