According to Apple, App Store sales rose 50% in 2014 year-over-year. Though they didn’t release specific numbers, 2013 saw $10 billion in sales via the App Store. That means 2014 ran $15 billion or more through the App Store, which amounts to a tidy profit for Apple. In keeping a 30% cut, Apple raked in $4.5 billion or better. It might not touch their hardware income, but the impressive growth does indicate they’re on the right track with software and services.
