Boost In-App Ad (IAA) Revenue
The offerwall is a great mobile monetization strategy for any micro-payment freemium app. Offerwalls can significantly increase your app revenue. They deliver extremely high eCPMs for app developers. The average offerwall eCPM for Android is $30 to $80, and the average offerwall eCPM for iOS is $50 to $120.
Offerwalls will help you keep your users within your app longer, ultimately increasing user retention. Offerwalls work particularly well for verticals like gaming, communication, texting, gambling or dating. Instead of quitting, users can access the offerwall once they are out of virtual currency, and get the premium content they need to continue playing.
