Musical.ly

Chinese social media service, now TikTok

Musical.ly was a social media service headquartered in Shanghai with an American office in Santa Monica, California, on which platform users created and shared short lip-sync videos. The first prototype was released in April 2014, and then after that, the official version was launched in August 2014. Through the app, users could create 15-second to 1-minute lip-syncing music videos and choose sound tracks to accompany, use different speed options and add pre-set filters and effects. The app also allowed users to browse popular "musers", content, trending songs, sounds and hashtags, and uniquely interact with their fans.
