You're playing a game. Or maybe you're just trying to check the weather. Suddenly, a neon-colored video for a "Royal Match" clone screams at you, taking over your entire screen for thirty seconds. It’s obnoxious. We all hate it. Trying to block in app ads iPhone users face daily has become a digital arms race, and honestly, Apple hasn't made it particularly easy for the average person to win.
Most people think a simple toggle in the Settings app will fix everything. It won't. Apple’s "Limit Ad Tracking" (now App Tracking Transparency) is a privacy feature, not a "hide all commercials" button. There is a massive difference between stopping a company from following you across the web and stopping them from showing you a picture of a burger while you're trying to count your calories.
The truth is that ads are the lifeblood of the App Store economy. Developers have to eat. But when those ads start draining your battery, eating your data plan, and making your $1,000 phone feel like a cheap billboard, you’ve reached a breaking point.
The DNS Trick: The Closest Thing to a Magic Wand
If you want to kill ads inside apps without jailbreaking your phone, you have to look at DNS. Domain Name System (DNS) is basically the phonebook of the internet. Every time an app wants to show an ad, it asks a server for that ad content. By changing your DNS to a provider that "sinks" those requests, the ad simply never loads.
AdGuard DNS is the big player here. You don’t even need their paid app for the basic stuff. You can actually download a profile directly from their website. Once installed in your iOS settings under General > VPN & Device Management, it acts like a filter for your entire device.
It’s not perfect. Some apps are smart. YouTube, for example, serves ads from the same domain as the video content itself. If you block the ad, you block the video. It sucks. But for those random puzzle games or utility apps? It’s a total game-changer. You’ll see a blank space where the ad used to be, or the app might just skip the "reward" video entirely.
Why some "Ad Blockers" on the App Store are scams
Go to the App Store right now and search for ad blockers. You'll find hundreds. Most of them only work in Safari. They use Apple's "Content Blocker" API, which is strictly limited to the browser. If a developer claims their $4.99/week subscription will block ads in Instagram or Facebook, they are lying to you.
Apple’s sandbox security model prevents one app from messing with the data of another. This is great for security—it means a calculator app can't steal your banking password—but it's terrible for ad blocking. To truly block in app ads iPhone apps generate, you have to go "outside" the app level and hit the network level.
Content Blockers vs. System-Wide Shields
There is a huge distinction here that people miss. Safari content blockers are passive. They tell Safari, "Hey, don't download these specific scripts." They are lightweight and won't kill your battery.
System-wide blockers like NextDNS or Lockdown Privacy are different. They create a "dummy" VPN on your phone. Your data doesn't actually go to a foreign server (usually), but the phone thinks it's on a VPN so that all traffic can be filtered through a blocklist.
NextDNS is probably the most sophisticated tool available right now. It gives you a dashboard. You can see exactly which apps are trying to "phone home." When I first set it up, I was horrified to see my smart-home app pinging a tracking server every 30 seconds. You can toggle specific lists like "EasyList" or "Fanboy’s Annoyance List." It’s nerdy. It’s effective. And for the first 300,000 queries a month, it's free.
The "Airplane Mode" Hack (The Low-Tech Savior)
Sometimes the simplest way to block in app ads iPhone software throws at you is to just cut the cord. If you’re playing an offline game—one that doesn't need a leaderboard or multiplayer—just swipe down and hit Airplane Mode.
No internet, no ads.
The app can’t fetch the video. It might try to show a "failed to load" message, but that's a half-second blip compared to a 30-second unskippable nightmare. Just remember that this won't work for "freemium" games that require a persistent connection to verify your currency or save your progress to the cloud.
What About YouTube and Social Media?
This is the hard part. Meta (Instagram/Facebook) and Google (YouTube) are too smart for DNS blocking. They bake the ads into the stream of content. To the network, the ad looks exactly like the photo of your cousin’s wedding.

For YouTube, the only real "official" way is YouTube Premium. I know, paying to stop ads feels like a defeat. But on an iPhone, because you can't easily install modded APKs like you can on Android (think ReVanced), your options are limited.
You could use a browser like Brave or Safari with an extension (like Vinegar or 1Blocker) to watch YouTube. It works. It kills the ads. But you lose the app's interface, which most people find annoying. It’s a trade-off. Convenience vs. Cleanliness.
Privacy Settings You Should Change Right Now
While these won't stop the ads from appearing, they stop the ads from being creepy. And occasionally, if an ad can't be "targeted," the system fails to serve one at all.
- Go to Settings.
- Tap Privacy & Security.
- Scroll to the bottom and hit Apple Advertising.
- Turn off Personalized Ads.
Next, go back to Privacy and find Tracking. Turn off "Allow Apps to Request to Track." If you’ve already said "Yes" to a bunch of apps in the past, you can see the list there and revoke their privileges one by one. It’s satisfying.
The Nuclear Option: Raspberry Pi and Pi-hole
If you really want to be the master of your domain, you look into a Pi-hole. This isn't an app. It's a physical piece of hardware (a tiny computer called a Raspberry Pi) that you plug into your router.
It acts as a DNS sinkhole for every device in your house. Your iPhone, your smart TV, your laptop. If it’s on your Wi-Fi, the ads get stripped away before they even reach the device. It’s the ultimate way to block in app ads iPhone and other devices encounter.
The downside? It only works when you're at home. The moment you switch to 5G or go to Starbucks, the ads come rushing back. You can fix this by setting up a WireGuard VPN to route your mobile traffic back through your house, but that's getting into "weekend project" territory.
Final Insights for a Cleaner iPhone
Don't fall for the "Free VPN" trap. If a VPN is free and claims to block ads, you are the product. They are likely selling your browsing data to the very advertisers you're trying to avoid.
Steps to take today:
- Install a DNS Profile: Use AdGuard or NextDNS for a 5-minute setup that kills 80% of "cheap" app ads.
- Audit your Apps: If an app is too aggressive with ads, delete it. There’s almost always a "Pro" version of a competitor that costs $2.99 once and stays clean forever.
- Use Safari Extensions: For web browsing, 1Blocker or AdGuard for Safari are the gold standards.
- Check your DNS settings: Go to Settings > Wi-Fi > [Your Network] > Configure DNS. Switching to Manual and using
9.9.9.9(Quad9) can provide a baseline of security and speed, though it’s less aggressive on ads than dedicated blockers.
The battle against intrusive advertising is constant. As soon as we find a way to block them, companies find a way to circumvent the block. But by moving your defense from the "app level" to the "network level," you regain control over your screen and your sanity. Keep your software updated, stay skeptical of "free" tools, and don't be afraid to pay a few dollars for an ad-free experience in the apps you use every single day. It's usually worth the price of a coffee to never see a "Level 1 vs Level 99" ad again.
