Comments on Rethink: DNS + Firewall + VPN for Android

★★★★★ Epic Man · Apr 28, 2026

Best app to harden your Android privacy and security-wise, hands down! I love the compatibility with Orbit! Overall, amazing app.

★★★★★ Deuce Bigalow · Nov 22, 2025

AWESOME APP! Allows routing over multiple VPN connections, customizable dns, and firewall. Logs show what your apps are doing and who they are calling. Thank you!!

★★★★★ Oliver · Feb 24, 2026

Great app if you get it elsewhere, because only then does it offer the feature to use local block lists

★★★★☆ Ainz Ooal Gown · Jan 28, 2026

I tried net guard, dns net, athena. Out of these rethink dns impressed the most. Why? Because it could be used with mullvad simultaneously. If it had 1 weakness, I checked GitHub seems lots of issues remain unresolved? Dev seems to be swamped with to-do list. But as long as it's fixed it has very good potential. This is a very important app to have. Fyi, the google play app is outdated vs GitHub, so i reco install from the GitHub instead. I donno y the dev have different version from GitHub

It worked great for a couple of weeks and then it stopped working. It fails to connect and says "no internet." I waited weeks and the issue did not resolve, so I will be uninstalling. Rebooting my phone or trying a different Wi-Fi connection did not help.
