NetSecWall for Android: what it does and how it works (beta)
A free beta DNS firewall for Android 7.0 and newer. It blocks ad, tracker and malware domains on the phone itself, with no root and no account. It isn't on Google Play yet.
Blocklists, overrides and DNS settings on Android
Turn lists on in the Blocklist tab and tap Update enabled to download them. Add overrides to always allow or block a domain, and set the resolver, DNS-over-HTTPS and block response in Settings.
How to block a specific domain or website
Add the domain to a content category that is set to Block: Protection ▸ Content categories…, select the category, type the domain and click Add. Its subdomains are blocked too.
Block website categories: ads, adult, gambling, social media and more
Open Protection ▸ Content categories… and tick Block for any of the 13 categories, or pick a Profile preset. NetSecWall then blocks the addresses those sites resolve to, in every app.
See which domains each app looks up
Open the DNS tab to see every domain each program looked up, how many times, and when it first and last did. Encrypted DNS inside a browser is the one common case it can't see.
Group live traffic by IP, domain, country or category
On the Live tab, change View from Apps to By IP, By Domain, By Country or By Category. Traffic is then totalled per destination, with the apps talking to each one listed underneath.
Network history, search and reports
The History tab keeps your PC's traffic per app and host, minute by minute, for as long as you like. Pick a time range, then filter by app, IP, domain, country or network owner.
