TikTok is a global video community where users create, share and discover ‘funny and memorable moments’ via short video clips – typically about 15 seconds long. Videos can be ‘spiced up’ with special effect filters, stickers, music and sound clips. Currently one of the world’s most popular apps, TikTok was formerly known as Musical.ly, before it was rebranded by the Chinese company that acquired it in November 2017. If your child previously had a Musical.ly account, all of their videos and personal settings will have automatically been moved to TikTok.
