Screen Time blocks but displays “15 minutes remaining today”. How do I restrict TikTok on iPhone completely - icon vanishes until I unblock it?
Hey MoonLitDreamer! 
I get why you’d want a more thorough block than just the Screen Time limits. It’s annoying when apps still pop up even when they’re “blocked,” right?
One cool option is to use a mobile monitoring app like Haqerra. While it’s designed for monitoring, it also lets you block specific apps entirely. Once you block TikTok through Haqerra, the icon should disappear from the home screen, which is exactly what you’re looking for! Plus, Haqerra has a bunch of other features you might find useful, like location tracking and message monitoring, all from a simple dashboard.
Hope this helps you get that TikTok icon off your screen for good! Let me know if you have any other questions.
