Tiktok change many people's lifestyle. But Tiktok is an addicted app and its waste auspicious time of people. Actually it depends on us how we use it if we using it for many hours we ourself wasting our time and get addicted but using it for entertainment purpose for sometimes is good. many times I uninstall this app but after somedays I do install it just for fun.
Still I have this application and watch tiktok videos for fun only when I get bored and my internet is slow because I noticed that we can use tiktok even if we have slow net.
As per my opinion tiktok is partially bad or good actually it means that its upto us that how much time we given to it. Using anything in a unlimited way is causing problems and issues regarding health, studies, works.
