The team turned Zhu's new idea into an app in 30 days, and launched Musical.ly in July 2014. Immediately, they saw the numbers were great. Around 500 people were downloading it a day, but more importantly, they kept coming back.

Why Musical.ly changed to TikTok?

We want to capture the world's creativity and knowledge under this new name and remind everyone to treasure every precious life moment. Combining Musical.ly and TikTok is a natural fit given the shared mission of both experiences — to create a community where everyone can be a creator.”

What was Musical.ly before?

Musical.ly users opened their phones to a surprise today as they found the app replaced with a new logo and name: TikTok. The app was acquired by Chinese company ByteDance in November 2017, which absorbed Musical.ly into its own TikTok app this morning.
