Can someone point me to some references for the following statement? I curious to read more:

  the revenue generated per active user by top apps on iOS is four
  times higher than the equivalent number on Google Play. The 
  majority of publishers don’t even bother to release paid versions
  of their apps on Google Play, opting to monetize using IAP and ad
  support, with the latter making up the lion’s share of profits.
