If you haven't heard of TikTok, you've likely heard of musical.ly, which, since August, has been re-branded as TikTok after being acquired by the app's parent company, ByteDance, back in November 2017. Whether it's on your radar or not, it is worth paying attention to. According to new research from Apptopia, TikTok is growing fast, with worldwide downloads up to 20 per cent in the last three months, and US downloads up to 25 per cent. In fact, TikTok is seeing more downloads than Snapchat, Instagram, Facebook and YouTube. Currently, TikTok has 130 million users, is growing fast, so while it may not have an audience comparable to most of the big social channels, it is getting more popular. The app's popularity has been boosted by the introduction of its 'Reactions' feature a few months back, which enables users to post their own video responses which play alongside the original clip. It is surely a revival of short video making, and a fun replacement of the famous app “Dubsmash”.
