• Android (Android 5.0 and up with Samsung Internet 4.0 and up)
• iOS (iOS 9 and up on 64-bit devices, iPhone 5s and up and iPad mini 2 and up)

Just as webpages grew bloated with ads, so too have ad blockers grown bloated with little-used filtering rules and features that sap their speed and hog your computer or device’s disk space, CPU cycles, and memory. Adblock Fast executes a mere 7 optimized filtering rules to accelerate pages 8x more but consume 6x less system resources than other ad blockers do.

1. Adblock Fast executes 7,000x fewer filtering rules per page.¹

• AdBlock: 49,002 rules
• Adblock Plus: 49,002 rules
• Adblock Fast: 7 rules

I.e., the app runs faster.

2. Adblock Fast consumes 7x fewer kilobytes of disk.²

• AdBlock: 843 KB
• Adblock Plus: 543 KB
• Adblock Fast: 97 KB

I.e., the app installs faster.

3. Adblock Fast accelerates page loading by 8x as many seconds.³

• No ad blocker: 3.17s (control)
• AdBlock: 2.84s (0.33s faster)
• Adblock Plus: 3.23s (0.06s slower)
• Adblock Fast: 2.10s (1.07s faster)

I.e., pages load faster.

4. Adblock Fast consumes a 3x lower percentage of CPU.⁴

• AdBlock: 19.4%
• Adblock Plus: 20.3%
• Adblock Fast: 6.6%

I.e., your computer or device runs faster.

5. Adblock Fast consumes 3x fewer megabytes of memory.⁵
