Not a clue, once again was hoping someone here knew. Must be something like Snapchat or Reddit. You know the latest thing.
TikTok is a Social media platform similar to what Vine used to be. Formally, it was known as Musical-y. Its basically where teens and tweens can post short videos of themselves lip-synching to songs or doing other various stuff. What kids really like about it is the side by side feature where you can literally place your video side by side split screen style with someone elses video to either complement it in some way, or mock It or whatever creative way you want to use it. You do not need the other parties permission to do this, which makes it fun
Unfortunately, the app is owned by a Chinese company. So the Chinese government is basically spying on these kids.
Tik Tok has Chinese spyware on it. Avoid it if you value the security of your smart phone.
