What Is Smule: Sing & Duet?

Smule is a leading social karaoke platform that combines a massive song library with collaborative duet features, positioning itself as a global hub for vocal practice and performance. By offering AI-powered audio tools, it appeals to both casual hobbyists and aspiring singers. Despite its strong market position, the app faces significant challenges, including a declining sentiment trend driven by aggressive monetization and technical instability on newer devices. To maintain its #13 Grossing rank, Smule must address these friction points to prevent user churn and improve its competitive standing against rivals like StarMaker.
