How to Download TikTok 18 on iPhone – Without Jailbreak

TikTok 18 is a modified version of the original app that allows access to 18+ content. However, because it’s a mod version that allows 18+ content, it goes against strict App Store policies. Because of this, you won’t find it listed on the App Store. Installing third-party or external apps on an iPhone or iPad isn’t as straightforward as on Android.

But don’t worry — that doesn’t mean you can’t use TikTok18 on your iOS device. You need to use trusted sideloading methods.In this guide, you’ll learn how to install TikTok 18 using three reliable tools:
