Released in 2014, Musical.ly built a massive following that seemed to hit its highest mark last year. The app lets you create 15-second music videos with different video and visual effects, then share to other Musical.ly members. Used by US teens and celebrities alike, the service seems like a perfect fit for Apple, who are currently looking to raise the visibility of video in their Apple Music ecosystem.
The Shanghai-based app developer also launched Livel.ly, a livestreaming app that hasn't quite caught on with teens like the original app did. Musical.ly is available on the iTunes and Amazon app stores and Google Play.
