1Blocker Review 2024: What Your iPhone Has Been Missing

1Blocker was built specifically for Apple operating systems and the Safari browser. It integrates with not only the browser, but all apps across the device protecting you from ads, trackers, cookies, and even the dreaded comments section of some sites. 

We found this software to be highly effective, even the free version, and cost-efficient. With high scores from the ad-block testers we used to block ads on our YouTube app, 1Blocker passed with flying colors.

• Works seamlessly on macOS and iOS
• Lots of options, including a firewall
• No smart toggles in iOS Safari

Our experience

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. On top of that, parental controls either seem hidden or nonexistent. Enter 1Blocker.

Before we tested 1Blocker, we went to sites like Reddit to see what actual 1Blocker customers had to say. For the most part, commenters seemed to like it. 

We started our test with the free version and were impressed with the ad-blocking capabilities. Once we moved to the paid version we were very impressed.

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. One caveat is that we found certain aspects of the apps 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 useful and powerful. The only problem was the inability to easily toggle the ad blocker off and on in Safari on iOS. This was strictly an iOS problem and didn’t happen when we used 1Blocker on Safari on our Macbook Pro. 

Otherwise, we had a positive experience and definitely recommend the product if you’re looking for a powerful tool for macOS or iOS.

1Blocker paid plan

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.

There are three subscription models offered. The first tier is monthly and comes in at a reasonable $2.99/mo. The annual plan is $14.99/yr (billed annually), which is also reasonable. 

There’s also a lifetime plan for $38.99 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.

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 (so you can allow ads on selected websites)
• Block Sites
• Block Cookies
• Hide Elements
• Force HTTPS

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. And Can You Block It checks your ad blocker's effectiveness against interstitial ads, ad blocker detection warnings, and banner ads.

Invisible trackers are code buried deep within a website that allows third-party entities the ability to build a profile of your internet activities. A fingerprint shows how unique you appear online, and the more unique you are the easier it is to identify you. If your score is general, which means you blend into the internet crowd, you’ll have more success browsing online anonymously.

We tested on both the paid and free versions of 1Blocker. The paid version was nearly perfect. It passed all of AdBlock Tester's tests but failed to block interstitial ads from Can You Block It. It also allowed some fingerprinting through.

When we tested the free version, it was still pretty good but not as effective. You can only enable one type of protection on the free version, whereas the paid plan allows you to enable all protections available with 1Blocker. 

We noticed this when we tested 1Blocker's free version with Cover Your Tracks. It received only a 1/3 with the Block ads toggle on but that score increased to 2/3 with the Block trackers toggle instead.

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 Tiny Desk concert 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 toggle off ad blocking within the app itself. Either way, this powerful tool lets you choose.

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 were disappointed that 1Blocker was not able to bring down paywalls on The Wall Street Journal, Bloomberg, or The Atlantic. But we'll keep testing ad blockers against paywalls with the hope that one will work. 

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.

How to use 1Blocker

Once you've settled and downloaded 1Blocker on your Apple devices, you'll need to enable content blocking. The settings differ with each device, so we'll break down the 1Blocker setup below. 

How to enable content blocking in Safari on iOS:

1. Open your iOS settings.
2. Go to Safari > Extensions.
3. Enable your preferred 1Blocker settings.
   

   

How to enable content blocking in Safari on macOS:

Top alternatives

1Blocker is a great service for Apple users, but it's not compatible with Windows or Android. If your household doesn't solely use Apple products, there may be some protection gaps.

FAQs

Bottom line: Is 1Blocker good?

Yes, 1Blocker is a powerful and useful tool. 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.

1Blocker is one of the best apps for Mac, Safari, and iOS devices, but our 1Blocker alternatives will make sure you'll be protected from ads, trackers, and malware across all your devices.
