How to Download TikTok 18 on iPhone

ByEvelyn Grace

Many people who feel bored with the official TikTok often ask me how they can run TikTok 18 on an iPhone — especially when it’s not available on the App Store. That’s why I’m sharing the exact method I use while installing external app on my iPhone—no jailbreak, no complicated tricks.

There are two reliable ways you can install this mod version on your iPhone:

  • Using Scarlet iOS
  • Using AltStore

Why Do People Want to Download TikTok 18 on iPhone?

When the official TikTok already has content from every category, why do people still look for this mod version? The primary reason is that many users desire more freedom than the regular app provides. As the official app doesn’t allow 18+ content.

Some people specifically want to watch mature or adult videos that aren’t available in the official version. Others look for extra tweaks — like blocking ads or saving videos without the watermark.

All of this is only possible through a mod version. However, keep in mind that an unofficial app can carry some security risks — so it’s essential to download it from trusted and well-known websites.

Why Isn’t TikTok 18 Available on the App Store?

Apple’s system is very strict when it comes to apps that include adult content or unauthorized tweaks. That’s exactly why you won’t find this app in the App Store. To get it, you’ll have to sideload it instead. Sideloading simply means you install the app manually — either through Scarlet or AltStore. Installing it on Android or PC is a simple and easy process.

How to Use Scarlet iOS

Scarlet is a third-party app store that lets you sideload apps on your iPhone without needing a PC. It’s an easy option for anyone who’s never sideloaded an app before or doesn’t want to use a computer for the process.

However, keep in mind that there’s a higher chance of certificate revocation with Scarlet. That’s because this IIPA installer signs apps using a publicly shared certificate — and Apple often revokes these certificates quickly if they’re abused. Once revoked, any app installed with that certificate will stop functioning. 

Step 1: Install Scarlet

To get Scarlet, download it from a trusted website. Open Safari on your iPhone, go to Google, and search for “Scarlet iOS.” Click the top official site that appears and download the software directly from there. Most of these sites also provide clear instructions on how to install it — simply follow them as shown.

Step 2: Download the TikTok 18 IPA

Once Scarlet is installed, visit tiktok18mod.com on your iPhone and download the latest TikTok 18 IPA file from there. Be sure to save it in a location that is easily accessible.

Step 3: Import and Install the IPA

Open Scarlet on your phone. Look for the ‘Import IPA’ option — tap it and select the IPA file you just downloaded. Then, tap ‘Sign’ and wait for the process to complete. When that’s done, tap ‘Install.’

Step 4: Trust the Profile in Settings

Go to your iPhone’s Settings > General > VPN & Device Management and find Scarlet’s developer profile. Tap it and trust it — this step is crucial, as the app won’t open otherwise.

Step 5: Launch TikTok 18 and Test It

Now, open the TikTok adult version and ensure it’s working correctly. If the app crashes, re-download the PA file — sometimes, the file becomes corrupted during the download process. If it still doesn’t open, the certificate may have expired. In that case, revisit the same site where you got Scarlet and follow the instructions to apply for a fresh certificate.

How to Use AltStore

Setup and use of AltStore is a slightly more technical, as it requires a PC or Mac, but the benefit is that it’s more stable than other sideload methods if set up correctly.

Step 1: First, download AltServer on your computer. You can easily find it on All Store’s official website.

Step 2: Connect your iPhone to your computer with a cable. Open AltServer and use it to install AltStore on your iPhone.

Step 3: Next, download the latest TikTok 18 IPA file from tiktok18mod.com.

Step 4: Open the AltStore app on your phone. Tap ‘My Apps,’ then tap the + icon. Find and select the TikTok 18 IPA file you downloaded. Tap ‘Install’ and wait for it to complete.

Step 5: Now go to your iPhone settings and trust the developer profile. If you skip this step, the app won’t launch.

Step 6: One thing to remember — any app you install with AltStore will expire every 7 days unless you re-sign it. Therefore, keep AltServer running on your computer whenever your phone is connected to maintain the app’s activity.

Important Things to Remember

  • Only download the IPA file from a trusted source — never download it from random links or unknown sites.
  • Never enter your TikTok username or password into any pop-up or suspicious login page while using a mod version.
  • Scarlet uses a publicly shared certificate, which means Apple can revoke it at any time. If that happens, simply revisit the Scarlet website you used previously and follow their steps to obtain a new certificate.
  • If you’re using AltStore instead, remember that apps installed through it need to be refreshed every 7 days — if you skip this step, they’ll stop working as well.
  • Since this TikTok mod can include mature content, it’s blocked in some countries. If you face regional restrictions, you can use a VPN — but choose a trusted, reliable VPN service only. Avoid free VPNs because they often leak your data instead of protecting it.

Problems and Simple Fixes

People often run into small issues like the app crashing or an “untrusted developer” message popping up. The fix is usually pretty simple:

  • If you see a trust error, remove the old profile first, then trust it again after reinstalling.
  • If the app keeps crashing, download a fresh IPA file directly from tiktok18mod.com — sometimes, files get corrupted during the download process.
  • If you’re using AltStore and it won’t sign the app properly, just re-enter your Apple ID details or restart your phone and computer. 

Worried About Using a Mod Version?

If you feel that using a mod version is too risky, then use the official TikTok app only. You can still adjust several settings, such as setting an age limit or using content filters to block unwanted content.

And if you’re trying to watch videos that aren’t available in your country, you can always use a good VPN. It’s safer than installing untrusted versions and still allows you to access blocked content without compromising your phone’s security.

Conclusion

Installing TikTok 18 on an iPhone is easy; simply follow the correct steps. The important thing is not to trust every link you see. It’s way better to get the file only from tiktok18mod.com — that keeps things safer. If you download it from a random site, there’s a good chance it may contain a virus or cause other problems.
