CPIs on Chartboost grew a modest amount for both Google Play and Amazon. CPIs for iOS, on the other hand, fell for both the iPhone and iPod while staying the same for iPad. While we?ve seen strong growth in CPIs for iOS devices over the past several months, it?s normal for them to level off in the summer. In that vein, the contraction observed in June wasn?t altogether unexpected.

Average Cost Per Install by Month


  • iPad average CPIs stayed flat with a 0% change
  • iPhone average CPIs fell by 2.7%
  • iPod average CPIs fell greatly by 16.7%

While cost per install on the iPad was flat, the fact that it?s sustained its CPI level speaks to the value that developers place on users of this platform. If you have a healthy base of players on iPad, you may want to consider new publishing campaigns where advertisers are eager to work with you. Otherwise we see a small drop in CPIs for the iPhone, and a more significant drop for the iPod. The list below details the countries that saw the largest iPod drops.
