Block This

Block This is a strong Android utility designed to block advertisements effectively on both apps and web browsers. Instead of constantly dismissing or ignoring annoying ads, you can browse with more peace of mind. The app relies on DNS filtering, meaning it can stop ad-related requests at the DNS level rather than only hiding elements inside a page.

Its main goal is to block unnecessary requests, which helps lower overall network traffic tied to ads and other related content.

Highlights

• Tap to enable: using Block This is as easy as pressing a single button.
• Optional auto-on: you can also choose to have the app start automatically when you turn on your phone, so you don’t have to tap again next time.
• Free to use: the app is 100% free. If you like it, you can support the developers through donations via:
  • Downloading other third-party apps (the easiest option)
  • Patreon
  • Direct donations through their PayPal account
• Minimal and focused: the app keeps things simple while helping you avoid the hassle of repeatedly closing unwanted ads.

Pros & Cons

Pros

• DNS-based blocking that targets ads and unwanted content before they load
• Works across apps and browsers, not only within a single browser
• No-root method using a dummy VPN approach to apply DNS changes
• Open-source codebase

Cons

• Listed as abandoned, so ongoing development and current support aren’t presented as active
• Effectiveness depends on DNS filtering, which may not block every ad in every app equally

FAQs

• Does it require root?

  No. It works on both rooted and non-rooted devices.

• How does it work?

  It works by updating your DNS settings and preventing ads/malware/spam from loading.

• How stable is it?

  The app uses multiple fast DNS servers located in Europe and the US. The service claims 99.99% uptime, meaning it should be unavailable for no more than 3–4 hours per year.



• Is it secure?

  It isn’t a real VPN. Your traffic isn’t tunneled through a remote server—DNS is used to instruct your phone what to do with requests related to ads/malware/spam.
