Why DNS Ad Blocking Beats Ad-Blocker Apps
Traditional ad blocker apps run a continuous background VPN service that consumes RAM, drains battery, and slows your device. Private DNS (DNS-over-TLS) is built directly into Android and iOS:
- System-wide coverage: Blocks ads inside free games, utility apps, and web browsers.
- Zero battery impact: Handled natively by the operating system kernel.
- Works on Wi-Fi and Mobile Data: Your protection stays active wherever you go.

[howto_callout type="warning"] Important Limitations:
- YouTube Video Ads: DNS filters cannot block ads played directly within the official YouTube app because YouTube streams ads from the exact same media servers as the videos. Use a browser extension or YouTube Premium for video ads.
- Public Wi-Fi Portals: Hotel or airport login pages occasionally block encrypted DNS. Simply set Private DNS to Automatic while logging in, then switch back.
