Rethink DNS + Firewall is an open-source Android app combining an encrypted DNS client (DoH, Oblivious DoH, DoT, DNSCrypt) with blocklists, a per-app firewall, and a WireGuard-based VPN/proxifier with split tunneling. It lets users block ads, trackers, and malware, control app internet access by rules, and route traffic through multiple tunnels.

Use cases

• block ads and trackers system-wide on android
• encrypt dns queries to bypass isp surveillance
• circumvent internet censorship on android
• block specific apps from accessing the internet
• route apps through wireguard tunnels with split tunneling
• monitor which apps make network connections
• use dnscrypt or dns over https on android

When to choose

• you want a free, open-source all-in-one DNS, firewall, and VPN tool on Android
• you need per-app firewall rules based on screen state, metered connection, or app category
• you want to combine multiple WireGuard tunnels with encrypted DNS in one app

When to avoid

• you need a firewall or DNS client on desktop platforms like Windows, macOS, or Linux
• you want a full commercial VPN service with managed servers rather than a client you configure yourself
• your device cannot run a local VPN service (e.g., managed restrictions preventing Android VPN slot usage)
