What is the best firewall app for android?

VPN
1

Iam looking for a firewall app on android and there are many options like NetGuard, TrackerControl, InviZible Pro and Karma Firewall.

What i really want in the chosen firewall is:

  • Being able to block app from connecting to the internet on mobile data or wifi or both.
  • Controling the ability of apps to connect to LAN network.
  • Stoping trackers or have another app to stop it. (Need suggestions please).
  • Having the ability to use DOH built-in.

P.s i don’t have a custom rom and it is so hard to have it in my country unfortunately.

Would you kindly help me finding the best of them all?

Rethink

Blokada 5 or pDNSf (Personal DNS Filter).

Bonus, if you want to use a real VPN at the same time, if that VPN provides OpenVPN config info (e.g. Proton does this for free accounts), then you can install the “OpenVPN for pDNSf” app to route DNS requests to pDNSf (for domain-based blocking) THEN route all traffic through your actual VPN!

I’m currently using TrackerControl and have it setup to run all my programs without any problems. I tested Rethink using Quad9 and RDNS with the blocklists enabled. Almost all my non-Foss apps are going to require some MAJOR setup . Seems to me that Rethink blows TrackerControl of of the water.

TC or netguard. AF if you are rooted

Sadly, all no root firewalls/ad blockers work via local vpn. And they drain battery because of this

After trying several apps/combinations of apps for weeks, I find rethink to be the best. No bad battery drain. Does not crash, not as often as other popular ones. Ton of options. Great logging, helps find bad apps.

But you can’t use NextDNS with that can you?

How is this better than Netguard? I use netguard mainly because it allows me to block the internet (Mobile+Wifi) for the applications.

Afwall+ is actually kinda outdated as its latest update was on 28 Jan 2022 also it is the same version that was released on F-droid on 3 July 2022!

TC is good bot no control for blocking internet from mobile data or WiFi, it is just blocking!
