🩺 Dr.Net — Network Diagnosis & Anti-Censorship VPN

Dr.Net is a free Android diagnostic and connectivity app that explains why a website or app will not open, then finds a working route with one tap. It tests each connection layer — internet, DNS, TCP, TLS, and HTTP — to distinguish filtering, sanctions-related restrictions, and connection problems.

🔎 Smart Network Diagnosis

- Test websites and apps step by step with clear explanations of failures. - Detect interruptions where pages begin loading but are then cut off. - Find the first route that works, then continue searching for a better one. - Save results separately for Wi-Fi and mobile networks and remember the best method for each. - Check built-in lists of popular services or enter any address.

🌐 Seven Built-In Connection Methods

Choose a method or let Diagnosis recommend one for your network:

- Lantern: Anti-censorship connectivity with country selection. - AmneziaWG: Obfuscated WireGuard over Cloudflare WARP or your own server. - Tor: Onion routing with obfs4 and Snowflake bridges. - Psiphon: Censorship circumvention with country selection. - WARP-on-WARP: A two-layer WARP tunnel. - WireGuard: Direct encrypted tunneling. - MASQUE: HTTP/3 and HTTP/2 transport over Cloudflare.

🧰 Tools That Do Not Need a VPN Server

- Google Relay: Route browser traffic through a Google script deployed in your own account, with quota monitoring. - Domain Fronting: Open selected blocked websites in Chrome using a clean domain; its certificate and private key are generated and kept on your device. - DNS Tester: Test dozens of DNS providers, including general, anti-sanction, gaming, and family options. - Clean IP Scanner: Find Cloudflare IP addresses that work on your network.

🔧 Your Own Configurations

- Import VPN configurations and subscription links. - Test server latency before connecting. - Create a lightweight Cloudflare Worker using your own account; keys stay on your device. - Add public free configurations manually.

🛡️ Everyday Connection Controls

- System-wide kill switch for built-in methods and imported configurations. - Per-app routing: tunnel all apps, selected apps, or exclude chosen apps. - Optional automatic reconnection and connection after reboot or app update. - Android Quick Settings tile and home-screen shortcuts. - Connection logs with weekly and monthly data usage. - In-app updates, Persian and English, and light and dark themes.

🔒 Privacy

Dr.Net states that it has no ads, analytics, tracking SDKs, or user accounts. It does not read phone identifiers, contacts, or Google account details. Configurations, settings, and account keys stay on the device, encrypted with Android Keystore. DNS is routed inside the tunnel, with IPv6 leak protection.

Connection logs are kept in memory; release builds do not record visited site names or addresses. However, external VPN or proxy operators may still see connection metadata.

📱 Requirements
