About this app

The Fiwalld is a free full-featured firewall on Android, keeps you away from malicious apps.
!!! Important: If you get "Trojan report" about Fiwalld by Antivirus scanners, it's a “false positive” report and please check the detailed statement at the end of the description.
Key features:
1. Real-time monitor which apps are accessing which servers or active sessions.
2. Default rules strictly blocks advertisements, malwares, spams, spyware & trackers, coinminer and prevents your system from connecting to them.
3. Easy use interface helps you to add your professional firewall rules just with few clicks.
4. Add or batch provision customed firewall rules for advanced users.
5. Multi-dimensional statistical analysis allows you to quickly identify suspicious applications.
6. Predefined non logging DoH/DNSCrypt Servers provide further protection of your privacy.
7. Support add custom DoH/DNScrypt or UDP DNS servers.
8. Support batch provision whitelist rules.
9. Support checking IP location detail info via external Map app by clicking the country flag.
10. Support Default Block All Mode.
11. Support IPv6 and IP stack mode selection.
12. Support "allow rules" under "default block mode".
If you receive a system prompt that Fiwalld is draining battery, don't panic. Fiwalld does the connecting work, while other applications save this part of the battery, so the overall battery consumption remains the same.
Please know you can't run Fiwalld and other VPN client at the same time, this is the Android System limitation.
!!! Important statement: Got some feedback from Fiwalld users. Some Antivirus scanners take "2.txt" file in Fiwalld apk as Trojan, please know the "2.txt" file is a pure text file which contains part of ads, trojan domains list that are used by Fiwalld to block them, so it's a "false positive" report by scanners. And some scanners like AVG already fix the incorrect result after I provide the Fiwalld app and test by them. Fiwalld strickly follows the Privacy Policy If you still have concerns, please contact me via
This firewall app uses the Android VPN Service to route traffic to itself so that it can be filtered on-device instead of on a server.

This Firewall is not asking access to storage, that's great. It will do extra connections, but to get information about the IPs, and that's fine.The monitoring with the flags...and block by countries, very nice feature that not to many Firewalls are offering it. What I would like...a dark mode, a search option on the rules section. Great job, easily you can see which app is trying to connect over and over,it even has an area that has the counts by categories. Also blocks ads, and works great 👍

Really good app with clean interface, but with powerful options inside! Works 100% on Android 11 (Oppo/Realme phone). Thanks a lot, the author! He even added some features, requested in comments here :) If there was a way one could chain the Fiwalld with an external VPN service (or some VPN app on the phone) - to get the firewall AND real VPN together... then we would have the best android firewall in the world!

Thanks for the review! On Android, only allow one VPN service to be started. So you can't chain VPNs. About the VPN feature, it's not in the develop plan right now, sorry about that.
