CopVPN – Fast & Secure VPN
CopVPN is a fast, secure Android VPN app built with Jetpack Compose, trusted by 100,000+ Play Store users. Powered by WireGuard and OpenVPN across 1,135+ servers in 65+ countries, it delivers sub-2-second connection times through protocol-level performance tuning — backed by a no-logs architecture, always-on kill switch, and per-app split tunneling.
Problem
Users needed a reliable way to protect their online privacy without sacrificing speed, especially on public Wi-Fi where data exposure is a real risk
Many existing VPN apps throttled bandwidth or leaked traffic on accidental disconnects
Few offered modern protocols like WireGuard, leaving users with slow, unreliable connections
Solution
Built CopVPN as a fully native Android app in Jetpack Compose, integrating WireGuard and OpenVPN across 1,135+ servers in 65+ countries — achieving sub-2-second connection times through protocol-level performance tuning. Added an always-on kill switch, auto-connect, per-app split tunneling, and a strict no-logs architecture, giving users both speed and verifiable privacy.
