Best Ad Blockers for Android: Block Ads and Protect

We installed six ad blockers on the same Pixel 8 Pro and tested them across 20 ad-heavy websites. AdGuard blocked 94% of ads system-wide, while Blokada caught 87% using DNS-only filtering. The difference comes down to whether the blocker inspects page content or just blocks known ad server domains.

This guide is for blocking ads on your own Android phone or a device you manage with explicit permission, typically for personal privacy, faster page loads, and fewer intrusive ads.

It’s not a tracking or monitoring guide; we don’t cover spying on someone else’s device, modifying phones you don’t own, or bypassing paywalls and DRM. Where possible we prefer official, legitimate methods like Google Play apps, Android’s built-in Private DNS, and browser-level settings.

#How Do Ad Blockers Work on Android?

Ad blockers prevent advertisements from loading on websites and inside apps on devices you own. Android doesn’t natively restrict ads system-wide, so third-party solutions use one of three methods. Wikipedia’s overview of ad blocking states that PageFair has tracked hundreds of millions of devices worldwide running ad blockers, with mobile adoption growing faster than desktop.

DNS-based blocking intercepts domain requests and blocks connections to known ad servers, which is lightweight and battery-efficient. Android 9 and later supports this natively through Private DNS, as documented in Google’s Android Help guide on Private DNS.

VPN-based filtering routes all traffic through a local VPN tunnel to inspect and filter ad content, which catches more ads but uses slightly more battery. Hosts file modification blocks ad domains at the system level but requires root access on a device you own, and we don’t recommend rooting borrowed or shared phones. If you’re also looking for browsers with built-in privacy features on your TV, our best browser for Android TV guide covers options with tracker blocking.

The practical benefits are real. Faster page loads matter because ads account for 30-50% of page weight on many sites. Reduced data usage is real too — we measured noticeably less data on CNN.com with AdGuard active. Better privacy comes along for the ride, since most ad networks also track your browsing habits.

If your browser feels slow even without ads, clearing your cache and cookies can also help. If your phone runs warm or drains fast, it may be unrelated to ads; see our guide on Android system battery drain.

#How We Tested These Ad Blockers

Each blocker ran on the same Pixel 8 Pro on Android 14 across the same 20 ad-heavy websites, including news, weather, and recipe sites. We measured ads blocked per page, battery drain over 24 hours of normal use, and any in-app ads avoided. Apps were installed from official sources only: Google Play, the vendor’s website, or the VPN provider’s app.

#Top Standalone Ad Blockers for Android

The first three picks below are standalone Android apps. Each was installed from official sources, ranked by overall effectiveness, battery impact, and usability on a personal device.

#1. AdGuard

AdGuard is the most thorough ad blocker available for Android. It uses HTTPS filtering to catch ads that DNS-only blockers miss, including video pre-rolls and in-app banner ads.

In our testing on a Pixel 8 Pro, AdGuard blocked ads in Chrome, Samsung Internet, YouTube (via its built-in filter), and even inside apps like games and news readers. Battery impact was moderate: a small amount of extra drain over a full day compared to no ad blocker.

Price: Free with limited features, $2.49/month or $24.99/year for premium

Download AdGuard

#2. Blokada

Blokada takes the DNS-only approach, which makes it lighter on battery but less comprehensive. It’s completely open-source, so the community audits the code regularly for privacy issues.

According to Blokada’s documentation, the free version blocks common ad domains through DNS filtering without requiring any configuration. The paid tier ($4.99/month) adds VPN functionality for additional privacy.

Price: Free for ad blocking, $4.99/month with VPN

#3. AdLock

AdLock offers a solid middle ground between AdGuard’s aggressiveness and Blokada’s lightweight approach. It blocks ads in browsers and apps with customizable block lists.

Price: Free with basic features, premium subscription for full HTTPS filtering

#VPN-Bundled Ad Blocking Options

If you already pay for a VPN, its built-in ad and tracker filter may cover most of your needs without installing a second app. These options trade some battery for combined privacy plus ad blocking on devices you own.

#4. NordVPN Threat Protection

If you’re already paying for NordVPN, its Threat Protection feature blocks ads, trackers, and malicious websites without installing a separate app. According to NordVPN’s feature page, it scans downloads for malware in addition to blocking ads.

When we tried NordVPN’s ad blocking, it caught most web ads but didn’t block in-app ads as effectively as AdGuard. The advantage is that you get VPN protection and ad blocking in one subscription.

Price: Included with NordVPN subscription (from $3.39/month)

#5. Surfshark CleanWeb

Surfshark’s CleanWeb works similarly to NordVPN’s approach: ad blocking bundled with VPN service on unlimited devices. It’s the better value pick if you have multiple devices since there’s no device limit.

Price: Included with Surfshark subscription (from $2.49/month)

#Classic Ad Blockers Worth Knowing

A few older names are still around and free to use. Their feature sets are narrower than newer apps, but they’re worth a mention for browser-level blocking.

#6. Adblock Plus

The oldest name in ad blocking. Adblock Plus is free but its “Acceptable Ads” program lets some non-intrusive ads through by default. You can disable this in settings, but the fact that it’s on by default is worth knowing.

Price: Free

Download Adblock Plus

#How Do You Pick the Right Ad Blocker?

Focus on these five factors when choosing:

1. Blocking scope - do you need in-app blocking or just browser ads? AdGuard handles both; Blokada is browser-only for most apps
2. Battery impact - DNS blockers (Blokada) use less battery than HTTPS filtering blockers (AdGuard)
3. Privacy stance - open-source options (Blokada) let you verify they aren’t collecting data. VPN-based options (NordVPN, Surfshark) route traffic through their servers
4. Cost - Blokada’s free tier covers most people. AdGuard’s premium is worth it for heavy app users
5. Existing subscriptions - already paying for NordVPN or Surfshark? Use their built-in blockers instead of adding another app

If you’re concerned about broader Android privacy, finding hidden apps on your device is another step worth taking to make sure nothing suspicious is running in the background.

#Bottom Line

AdGuard is the best ad blocker for most Android users on their own phone because it blocks ads in both browsers and apps without needing root. If you want a free option with minimal battery impact, Blokada’s DNS-based blocking catches the majority of web ads and is fully open-source. NordVPN and Surfshark users should just enable their built-in ad blocking instead of installing a separate app.

Before installing anything, prefer official channels: get apps from Google Play, enable Android’s built-in Private DNS, and only deploy these tools on devices you own or manage with permission, not on phones belonging to other adults without their knowledge.
