About this app
Rethink: DNS + Firewall + VPN is a comprehensive, open-source Android tool from Celzero that merges three crucial privacy features into a single, ad-free package. It provides a customizable firewall for per-app internet control, secure DNS filtering across 300+ global server locations, and built-in WireGuard VPN connectivity. Unlike most VPN apps, Rethink can operate alongside other VPNs like Mullvad for layered security, making it a powerhouse for privacy enthusiasts. The detailed connection logs and per-app rules give you granular oversight of network traffic, helping block ads, trackers, and malware domains. However, the interface and technical concepts can be overwhelming for newcomers, and some users have reported occasional disconnects or DNS delays. Features like screen mirroring may not work while the app is active. Ideal for power users who want transparency and control without subscription costs, Rethink strikes a balance between advanced functionality and the trade-offs of a community-driven, open-source project.
