Flurry

Flurry was a mobile advertising and analytics platform acquired by Yahoo in 2014. It provided app developers with tools to measure user engagement, monetize their apps with advertising, and understand user behavior. Flurry Analytics helped businesses understand app performance, user demographics, and in-app actions. Flurry`s ad exchange facilitated the buying and selling of mobile advertising inventory. While Flurry is no longer an independent company, it remains a valuable resource for app developers and advertisers within the Yahoo platform.
