Android users pay for ad blockers that initially work but gradually stop blocking ads, redirects, and trackers on specific websites or inside apps. Failures vary between Wi-Fi and mobile data, while users often cannot tell whether protection is active until intrusive ads return. Existing products also accumulate unrelated browser regressions, weakening trust in the core blocking job.
Build a focused Android blocking service with a lightweight local VPN?, frequently updated filtering rules, and automated tests against a published set of popular sites and apps. Let customers report a failed page or app in one action, reproduce the failure on test devices, and distribute a rule update without requiring a full application release. Start with browser and DNS?-level blocking, clearly identifying apps where encrypted or first-party ads cannot be removed reliably.
Multiple products are showing declining effectiveness as publishers and app developers change ad delivery and blocker-detection methods. Users explicitly report abandoning paid tools and searching for replacements, creating an opening for a provider that sells measured reliability rather than a static blocker.

I had to remove a star because although the app blocks banner ads and video ads on most apps, it doesn't block video ads on MP3 player apps. All in all it's a good app.
i have been using this app for a couple years and i used to really love it. it blocked everything in the mobile games. but the last couple month it constantly freezes or crashes and the vpn is always disconnecting and reconnecting aswell as ads showing up in different apps. not sure what happend but hope it fixes.
Awesome security I feel very secure when I connect the VPN and it blocks ads I don’t want to see. The only issue I have is that it seems to interfere with sites I do want to see, even when I disconnect the VPN. For example, I can no longer access my state government site because of security issues. I haven’t addressed this with AdGuard yet but I will.
Go beyond the grade and inspect the evidence behind this opportunity.
