Case Study: Etermax achieves 125% higher retention with AppBoy

How Appboy Helped Improve Retention in the World’s Top Apps By 125%

Etermax, the Buenos Aires–based studio behind Trivia Crack (Apple’s top free app of 2015), wanted to move beyond user acquisition and improve retention and re-engagement across its iOS and Android apps.

By integrating the Appboy SDK and running weekly, targeted push campaigns—personalized by language and social prompts—Etermax tracked and iterated on messaging. The result: month-over-month retention gains, with Weeks 1–2 up 40–50% and Week 4 retention rising 125% (November vs. September 2015) across its four Trivia Crack apps.
