RethinkDNS – monitor app activity, block ads and firewall apps on Android
It took me a second to grok that this is really mostly just an OSS Android app with some associated DNS servers you can optionally use with it. It&#x27;s not in F-Droid yet (which I personally consider to be a hard requirement for this class of software) because it includes proprietary bits, but here&#x27;s the link to the F-Droid issue for those who want to keep an eye on it:<p><a href="https:&#x2F;&#x2F;gitlab.com&#x2F;fdroid&#x2F;rfp&#x2F;-&#x2F;issues&#x2F;1552" rel="nofollow">https:&#x2F;&#x2F;gitlab.com&#x2F;fdroid&#x2F;rfp&#x2F;-&#x2F;issues&#x2F;1552</a><p>In the meantime, there&#x27;s DNS 66, which includes some similar features (minus the app firewall)<p><a href="https:&#x2F;&#x2F;f-droid.org&#x2F;en&#x2F;packages&#x2F;org.jak_linux.dns66&#x2F;" rel="nofollow">https:&#x2F;&#x2F;f-droid.org&#x2F;en&#x2F;packages&#x2F;org.jak_linux.dns66&#x2F;</a>
