Who spends more money on apps?

The latest study shows: iOS users still spend the most money on apps.

That requires an officially sanctioned head-to-head comparison between Apple’s App Store and Google´s Play Store:

With half as many users on iOS then Android, Apple has almost twice the app sales.

 But Android has made leeway the last months and maybe it will draw even with iOS soon.
