Musical.ly (stylized as musical.ly) is a Chinese video social network app for video creation, messaging, and live broadcasting. The first prototype was released in April 2014, and the official version was launched in August of that year. Through the app, users can create 15-second to 1 minute videos and choose sound tracks to accompany them, use different speed options (time-lapse, slow, normal, fast, and epic) and add pre-set filters and effects. The app also allows users to browse popular “musers,” content, trending songs and sounds and hashtags.
As of July 2016, musical.ly has over 90 million registered users and an average of 12 million new videos posted every day and by the end of May 2017 the app reached over 200 millions of users.
