This is a little ambiguous. How is “revenue” defined? Is it only purchases made directly by users or does it also include ad revenue? If former, then the comparison is useless because vast majority of users on android are using ad-funded apps where revenue flows from advertisers to the ad platform (Google etc). Devs could be using third party ad platforms too and it would be nigh impossible to estimate this revenue.
