Smule's Musical Social Network



Smule Nation is a social network spanning several popular apps, built on musical collaboration. Today it's about 200,000,000 strong worldwide.

I designed a suite of social features for AutoRap, including feeds and notifications to facilitate rap battles and cyphers.

Below is a trendline for the collaboration rate in AutoRap, over the course of developing these features. The increase is +5,000% from the baseline.


I extended this work to the core social infrastructure for Sing! Karaoke, to help users find their favorite partners to duet with.
