What it does

Attribr is an install-attribution SDK for iOS and Android that answers three questions for indie developers: where did each install come from, are those users still active at day 7/14/30, and which Rippl promoter drove a CPI install. 50KB SDK, zero third-party dependencies, sub-50ms launch overhead. Works without ATT permission via deterministic + probabilistic matching. The only attribution SDK with a direct bridge to the Rippl performance-marketing platform for community-driven CPI.
