How to remove TikTok from my iPhone?

The easiest way is to long hold on the app instead of the regular touch and then it should give you the option to remove or delete it. If it's inside of a grouping of other apps, simply click into the family of apps and then do the same long hold to remove.

Not knowing exactly what "everything" you have tried to remove the TikTok app from your iPhone, it would help if you can provide those steps.

Otherwise, have you simply tried deleting the app, like any other third-party app from your iPhone using the standard method of long pressing on the app until you see the list of options. Then tap on "Remove App?" If you did, what exactly happens?

Just to let you know. Removing the TikTok app from your phone does NOT actually delete your TikTok user account. TikTok provides you with a means to do so ... and one method they provide is via their app itself. Otherwise, if you already deleted the app, you can try accessing your TikTok account via a web browser on your phone or computer.

Do you use the Safari app for web browsing on your iPhone? Did you save TikTok's website as a favorite? ... or are you finding it in a list of sites that you have already been to?

You're very welcome! I'm glad you got it worked out.
