Musical.ly was a Chinese social media service headquartered in Shanghai with a US 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 the official version was launched in August of that year. Through the app, users could create 15-second to 1-minute lip-syncing music videos and choose sound tracks to accompany them, 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.
