Who the cares if there's 2M vs 2.2M? The vast majority of people use the same apps: Facebook, Twitter, a few store apps, the popular game(s) du jour (Candy Crush, Pokemon, etc) The remaining tend to be hidden-browser style apps for stores.
Literally 95% of those apps could disappear and nobody would give two shits.
I mean, if you really want to get technical, generally speaking, only one app (on idevices) can crash at any given time. On Android, there can be a lot more running tasks for customizations and system changes. Logically speaking, Android SHOULD be the one that crashes more since there's a lot more interactions going on.
Apparently the the parent poster does since he said that the availability of more apps on the iPhone contributes to more crashes.
Sounds like weak logic, but that assumption is not even true.
