You are wrong. This is reading the iOS notification center service and sending the messages to a specific receiver on the Mac in the same way a Pebble communicates with an iPhone. Growl is a Mac framework that apps can interface with to show notifications, but was largely replaced by Notification Center. Growl added a bridge feature for the MAS version, but is pretty largely unnecessary now. This app isn't part of the Android ecosystem, so it's not worth comparing or relating it to anything on Android. They've had this capability for a long time thanks to intents and listeners.
