1Blocker Review 2025: What Your iPhone Has Been Missing

Most ad blockers aren't built for Apple products. Even when there's a version compatible with iOS, macOS, or Safari, it usually has fewer features or doesn’t work quite right. Enter 1Blocker.

1Blocker was built specifically for Apple operating systems and the Safari browser. It had some perfect and near-perfect ad blocking rates during our testing, and has continuously thwarted YouTube's ads too. 

We were disappointed by its lower than usual tracker blocking score, but found a lot that we liked about this blocker overall. Learn more about our experience in our 1Blocker review.

Our experience

1Blocker improved our iOS and macOS experience. We were able to seamlessly browse the web, use apps, and click links without worrying about constant tracking. 

With all ad blockers we've reviewed, we visit the Forbes homepage because it's riddled with ads. 1Blocker got to work, taking down 14 blocked requests, including ads, trackers, and annoyances. 

We like that 1Blocker's dashboard is composed of all the toggles you can enable and descriptions of how they work. You can simply turn on the toggle and let 1Blocker do the rest or you can click through each individual toggle for more customization. 

During past testing, we've found that certain app aspects didn’t work as well with all functions of 1Blocker turned on. We also found that some images failed to load on sites and within emails. 

This was an easy fix, however. 1Blocker allowed us to toggle off the firewall for a certain amount of time, which allowed us to view these images (that we realized were laden with trackers).

Overall we found 1Blocker to be an effective tool. We definitely recommend the product if you’re looking for a powerful tool for macOS or iOS.

Mobile experience

1Blocker is just as easy to integrate into your iPhone app arsenal. Once the app was installed, 1Blocker linked us to our Safari settings to enable all its toggles. 

It has the same list of toggles as on Safari, so all you have to do is decide what kind of content you wish to block and let the app do the work. You can click through the toggle categories and find specific types of content to block too.

1Blocker can't block ads in the YouTube app, but this is the norm for ad blockers we've tested on mobile. But it can block ads on the YouTube website. We tested this function out and can confirm it works.  

1Blocker received perfect scores on the AdBlock Tester and Can You Block It tests. Although it struggles with tracking protection on mobile, we still feel good about using it for a clean browsing experience. 

1Blocker paid plan

1Blocker has a free version and paid plans for $1.25–$2.99/mo. There are three subscription options but the only difference is the length of your subscription. 

The first tier is monthly and comes in at a reasonable $2.99/mo. The annual plan is $1.25/mo (billed annually), which is also reasonable. 

There’s also a lifetime plan for $39.99 that’s a one-and-done payment. If you plan on using 1Blocker for three or more years, consider the one-time payment plan and never worry about it needing to renew.

If you want to get the most out of 1Blocker by accessing all the content blocking it has to offer, you’ll need to go with a paid plan. In addition to unlocking all the current features, you’ll also receive weekly updates and new features before they’re released to those using the free plan.

Main features

The features and customization options on 1Blocker’s paid plan are extensive and highly customizable. Features for Safari are broken down into General, Regional, and Custom options.

There’s also a firewall feature that blocks in-app trackers. When you open social media apps, 1Blocker stops them from collecting data on everything else you’re doing on your device, or where you’re going if your location services are active. (Yeah, social media apps do that, and so do other apps.)

General

The general Safari filters include:

• Blocking ads on sites
• Blocking web trackers
• Blocking annoyances, such as mobile app banners and crypto mining
• Blocking widgets
• Blocking comments where they aren’t the primary focus
• Blocking adult sites

Regional

The regional Safari filters block ads in these specific countries:

• Russia
• Germany
• Spain
• Italy
• France
• China
• Japan
• Holland (Dutch)
• Poland

Custom

Custom rules allow you to create your own options on webpages by using the app’s templates. These rules include:

• Allow List: Turn off blocking for your favorite sites
• Block Sites: Configure rules to block any site or page
• Block Cookies: Ignore cookies when sending requests to sites
• Hide Elements: Visual editor for hiing buttons, sidebars, or other elements
• Force HTTPS: Allows you to make websites HTTPS-only

Firewall

The firewall feature is useful for blocking in-app trackers. Trackers can do anything from collecting data on the other sites you’re using (and what you’re looking at on those sites) to allowing apps to continue tracking your geolocation if your location services are turned on. 

If you aren’t interested in being under constant surveillance, 1Blocker’s firewall can help. It even integrates with Siri to allow you to toggle off and on through voice commands.

1Blocker's test results

We use AdBlock Tester, Cover Your Tracks, and Can You Block It to test how well an ad blocker works. 

AdBlock Tester uses various analytics and advertising services to see how effective an ad blocker is when installed. Cover Your Tracks tests trackers, invisible trackers, and your online fingerprint. Finally, Can You Block It checks your ad blocker's effectiveness against interstitial ads, ad blocker detection warnings, and banner ads.

First, 1Blocker received a perfect score from AdBlock Tester. 

Then, Cover Your Tracks let us know that 1Blocker provides some protection against tracking, but there are gaps as well. It's previously provided strong protection against tracking, so this was a disappointing result. 

Last, 1Blocker got a near-perfect Can You Block It score. It blocked the banner ads and ad blocker warning completely, it just failed to skip over the interstitial ad.

YouTube ad test

Yes, 1Blocker does a great job of blocking YouTube ads without lag time. Because 1Blocker is built to run on an operating system rather than a browser, it even blocks ads in the YouTube app on an iPhone and iPad. That means no more going through Safari for ad blocking when you want to watch a video.

We started a YouTube video with 1Blocker off and were bombarded with the usual preroll ads and banner ads.

As soon as we enabled 1Blocker, our YouTube stream was seamless with no interruptions.

1Blocker also gives you the ability to toggle off ad blocking so you can continue to support your favorite creators with ad revenue. If you’re using it on a Mac, you can toggle off from the browser extension. If you’re using 1Blocker on an iOS device, you can turn off the block ads toggle while on YouTube. 

Bypassing paywalls test

We imagine most readers have felt annoyed when opening up an article on sites like The New York Times and being blocked by a paywall. That's why we test all of our ad blockers against paywalls to see which ones can bring down those walls. 

We didn't expect 1Blocker to bypass paywalls as most of the ad blockers we've tested fail this test. It failed against The Wall Street Journal and Bloomberg, but unblocked a paywall on The Atlantic. 

Although it didn't unblock all the paywalls we tried, we still found this promising. 

What browsers and software is it compatible with?

1Blocker is built exclusively for macOS, iOS, and Safari. If you’re hoping to install it on other browsers such as Chrome, Edge, or Firefox, or on a Windows, Linux, or Android device, you won’t be able to do that.

Because 1Blocker is built for Apple devices, it integrates seamlessly with each operating system and syncs across your devices. We’ve been using 1Blocker on our Mac and iPhone and the permissions and whitelists transfer. We’re also able to share it through Apple’s Family Sharing with our family members for no additional cost.

The following are some of our favorite 1Blocker alternatives based on their test scores, pricing, compatibility, and more.

FAQs

Bottom line: Is 1Blocker good?

Yes, 1Blocker is a powerful ad blocker for Apple aficionados. Although other ad blockers such as AdGuard or Adblock Plus do work on Apple devices, 1Blocker was built specifically for these operating systems and integrates beautifully. It provides you with features to keep yourself from being tracked and to allow a clean browsing experience.

There are some slight issues with 1Blocker, such as the inability to easily toggle off and on in Safari on iOS devices, that keep 1Blocker from being perfect. However, the protection, parental controls, and customization options make up for that issue in our opinion. If you’re looking for a way to enhance your experience on your iOS, macOS, and Safari devices, 1Blocker may be the perfect solution.
