Apple is still miles ahead when it comes to real time audio processing apps. The obvious example here being garage band, but on the less obscure side there are a ton of guitar amp/effects apps on iOS (which are awesome if you play guitar) for which there is absolutely nothing even remotely equivalent on android. My understanding is that the android api has improved recently with respect to the ability to support these types of apps, but for whatever reason there's still a noticeable lack of these apps.
