I mean obviously TikTok keeps their data close so we only have anecdotes.

But anecdotally for myself and anyone I know who has used TikTok, the app is just so much more addicting than any other social media has been before. I'm not a social media newcomer, I have used social media nearly all my life. I have used instagram in the past.But never before have I felt the same addiction/compulsion that exists with TikTok. I don't think this is that unusual an experience, have you tried using the app yourself?
