AdGuard review: our verdict

This AdGuard review covers one of the few ad blockers that works beyond the browser. AdGuard makes free browser extensions, but its main products are paid apps for Windows, Mac, Android and iOS that filter ads, trackers and dangerous sites across the whole device, including inside other apps. That reach is the reason to choose it, and also the reason it takes more setup than a one-click extension.

Our assessment is that AdGuard is the most complete option for people who want ad and tracker blocking on phones as well as computers, with one licence covering a mix of devices. Independent testers consistently rate its blocking among the best available. The trade-offs are a busier set of settings, a more involved install on Android, and the fact that the full apps need a paid licence. This is an editorial assessment based on AdGuard's own product, licence and privacy pages and on independent reviews and test results; NerdBible did not run its own hands-on trial.

What AdGuard is and who it is for

AdGuard is a family of privacy products from AdGuard Software Limited, a company registered in Limassol, Cyprus, according to its privacy policy. The ad blocker comes in several forms: free extensions for Chrome, Firefox, Edge, Safari and other browsers; full system-wide apps for Windows, macOS, Android and Linux; an iOS app that blocks content in Safari and adds DNS-level protection for other apps; and separate products such as AdGuard DNS, AdGuard Home for routers and AdGuard VPN.

It is best for people who are bothered by ads and tracking in apps, not just on websites, and for households that want the same protection on a Windows laptop, an Android phone and an iPhone without juggling several products. It is less suited to someone who only browses on one computer and wants zero configuration; a free extension may be all that person needs.

Key features

System-wide ad and tracker blocking

On Windows, AdGuard describes its app as blocking pop-ups, video ads, banners and other annoyances in all browsers and in apps, using background filtering and cosmetic clean-up so pages look tidy rather than broken (AdGuard for Windows). A tracking protection module, formerly called Stealth Mode, blocks third-party cookies and analytics systems. TechRadar highlighted the option to make cookies self-destruct after a set time and to send Do Not Track signals.

Video and in-app ads

Independent reviewers agree that AdGuard handles hard cases well. TechRadar was particularly impressed with how it dealt with YouTube ads, and AllAboutCookies reports that pre-roll, mid-roll and banner ads on YouTube were blocked on both desktop and mobile. Because the apps filter traffic at the system level, they can also remove ads inside free mobile games and other apps, which a browser extension cannot touch.

Browsing security and parental filters

The desktop apps check sites you visit against a database of phishing and malware pages and block dangerous requests. A parental control module hides inappropriate sites from search results and lets you build custom blocklists, which is useful for a shared family computer.

Filters and fine control

AdGuard lets you choose from many filter lists, add your own rules, allowlist sites you want to support, and even invert the allowlist so ads are blocked only on the sites you name. On iOS, AdGuard says you can pick from more than 50 Safari filters (AdGuard for iOS). Reporting screens show what was blocked on each page, which helps when a site misbehaves.

How AdGuard works on each platform

  • Windows and Mac: full apps that filter all traffic on the computer. AdGuard's licence guide lists a 14-day free trial for each.
  • Android: the full app is not on Google Play. AdGuard explains that Google does not allow network-level ad blockers there, so you install an APK from AdGuard's website, allow installs from that source, and let the app create a local VPN connection that filters traffic on the device rather than sending it to a remote server (Android installation guide). AdGuard also recommends enabling HTTPS filtering, which involves installing a certificate. There is a 7-day trial.
  • iPhone and iPad: Apple's rules limit what any blocker can do, so AdGuard for iOS combines Safari content blocking with DNS-level protection that covers other apps. Premium features can be bought in the App Store, unlocked with an existing AdGuard licence, or obtained through the separate paid AdGuard Pro app.
  • Browsers: free extensions for the major browsers. They block web ads well but lack the system-wide reach and extra modules of the apps.

How much does AdGuard cost? Plans and pricing structure

AdGuard's licence page sets out a simple structure, and our page shows current prices.

  • Free options: the browser extensions are free, and the iOS app has a free tier with basic Safari blocking.
  • Personal licence: covers three devices.
  • Family licence: covers nine devices.
  • One year or lifetime: both licences are sold as an annual subscription that renews automatically, or as a one-time lifetime purchase.
  • Universal: a licence bought from AdGuard's website works on Windows, macOS, Android and iOS, and can be moved between devices from your AdGuard account. Licences bought through the App Store are tied to Apple devices on the same Apple ID.
  • Refunds: AdGuard offers a 30-day money-back guarantee on website purchases.

AdGuard VPN and the paid tiers of AdGuard DNS are separate products with their own subscriptions. AllAboutCookies confirms they are not part of the ad blocker licence.

Is AdGuard safe? Privacy and security

An ad blocker that filters everything on your device sees a lot of traffic, so the company's data practices matter. AdGuard's privacy policy says its apps filter traffic locally on your device, that it does not know which websites you visit, and that it does not sell or share personal information. The apps contact AdGuard's servers to download filter updates and check licence status. Account data is limited to an email address and a password hash, and payments are handled by third-party processors. As a Cyprus-registered company, AdGuard operates under the EU's GDPR, a point Adblock Tester also makes.

Two settings deserve a moment's thought. On Android, the local VPN is how AdGuard filters traffic; it does not route your browsing through AdGuard's servers. HTTPS filtering, which AdGuard recommends for the best blocking, works by installing a certificate so the app can inspect encrypted traffic on your own device. That is a normal technique for this kind of tool, but it means you are placing a high level of trust in the app, so install AdGuard only from its official website or app stores.

What could be better

  • Setup takes effort. AllAboutCookies notes that several useful filters are off by default, so new users get weaker blocking until they adjust settings. The Android APK install is also more involved than tapping Install in a store.
  • Full features cost money. The free extensions are good, but system-wide blocking and the extra modules need a licence after the trial.
  • A busy interface. There are a lot of toggles and statistics, and AllAboutCookies found the statistics screens short on explanation.
  • Uneven mobile experience. iOS limits what AdGuard can block outside Safari compared with Android.
  • Occasional bugs. TechRadar listed occasional bugs among its reservations, and any aggressive filter can sometimes break a page until you allowlist it.

Who should choose something else

If you only use one desktop browser, a free extension such as uBlock Origin, or AdGuard's own free extension, may do everything you need. If you use Brave, its built-in blocker covers most web ads without anything extra. If you want network-wide blocking for every device in the house, including smart TVs and consoles, a DNS-based tool such as AdGuard Home on your router or a paid DNS filtering service may suit you better than installing apps one by one. And if you are not comfortable sideloading apps or installing certificates on Android, consider a simpler private DNS setting instead, accepting that it blocks less.

What other reviewers found

  • TechRadar called AdGuard a robust, widely compatible ad blocker, praising its YouTube blocking, inverse allowlist and website security check, with a limited free tier and occasional bugs as the downsides.
  • AllAboutCookies rated it highly as a cross-platform blocker after it achieved top marks on public ad blocking test pages, but warned that it is not a set-and-forget product.
  • ZDNET included AdGuard among its recommended ad blockers and described it as a good choice for beginners because its configuration settings are easy to understand.
  • Adblock Tester reported a perfect score on its own test page and praised AdGuard's reach across computers, phones and network devices, while noting that email support response times vary.

Where they agree: every outlet rates AdGuard's blocking quality highly, singles out its YouTube and in-app blocking, and values the breadth of platforms one licence covers.

Where they differ: ZDNET calls the settings beginner friendly, while AllAboutCookies says reaching full strength means switching on several options yourself. TechRadar's older review also suggests the paid plans include a VPN; AllAboutCookies and AdGuard's own licence page treat AdGuard VPN as a separate purchase.

What that means for you: expect excellent blocking once AdGuard is configured, but set aside ten minutes to go through the filters after installing. Budget separately if you also want AdGuard's VPN.

Is AdGuard worth it? Bottom line

AdGuard is the strongest choice for people who want ads and trackers gone across phones and computers, not just in one browser. A single licence covers a mix of Windows, Mac, Android and iOS devices, the blocking is consistently rated near the top, and the company's stated privacy practices are clear. It asks more of you at setup than a simple extension does, and the full apps are paid, but for multi-device households it offers more control than most alternatives.

Frequently asked questions

Is AdGuard free?

Partly. AdGuard's browser extensions are free, and the iOS app has a free tier with basic Safari blocking. The full system-wide apps for Windows, Mac and Android come with a free trial, 14 days on computers and 7 days on Android, and then need a Personal or Family licence. You can pay yearly or buy a lifetime licence, and website purchases carry a 30-day money-back guarantee.

Does AdGuard block YouTube ads?

Independent reviewers report that it does. TechRadar was impressed by how AdGuard handled YouTube ads in the browser, and AllAboutCookies found pre-roll, mid-roll and banner ads blocked on desktop and mobile. Results can change when YouTube updates its systems, so keep your filters updated. On iPhone, blocking is strongest in Safari, because Apple limits what blockers can do inside other apps.

Why is AdGuard for Android not on Google Play?

AdGuard says Google does not allow apps that block ads in other apps to be distributed through Google Play. The full AdGuard for Android app is therefore installed as an APK from AdGuard's own website, after you allow installs from that source. Once installed, it creates a local VPN on the phone to filter traffic on the device itself, rather than sending your traffic to a remote server.

Is AdGuard safe to use?

AdGuard states that its apps filter traffic locally, that it does not know which sites you visit and that it does not sell personal information. The company is registered in Cyprus and works under the EU's GDPR. Because the apps can inspect encrypted traffic on your device when HTTPS filtering is on, install them only from AdGuard's official website or the official app stores.

How many devices does an AdGuard licence cover?

A Personal licence covers three devices and a Family licence covers nine. Licences bought on AdGuard's website are universal, so the same licence can protect a mix of Windows, Mac, Android and iOS devices, and you can move it to a new device from your AdGuard account. App Store purchases are tied to Apple devices signed in with the same Apple ID.
