With a billion monthly active users, and a constant stream of new content, this social app is pretty much guaranteed to have a video to make you smile. And if it’s trending, you’ll find it in TikTok.

What we love: It’s endlessly entertaining – and sometimes educational! TikTok’s infinite scroll of new videos combines perfectly edited lip-syncing, hilarious sketches and mesmerising dance moves with delightful special effects and filters. It’s hard not to fall in love with everyone’s fluffy pets, awkward parents, impressive glow-ups, fails of every kind and songs and pop-culture references that spark a million memes.

Quick tip: Found a user you like? Tap their handle in the app to see what else they’ve posted. Or tap the audio link at the bottom to see other videos that use the same song or voiceover. If you really like someone, tap their profile photo to follow. New videos they post will get added to your Following tab.

Meet the creator: Since its launch in 2016, TikTok has grown to be as far-flung as its user base: the developer now has offices spanning from Los Angeles to Tokyo, and Berlin to Jakarta.
