About this app
Fast censorship-resistant VPN · Android and Windows VLESS · Reality · XHTTP over Xray and sing-box, Hysteria2 (QUIC), obfuscated AmneziaWG, a tunnel through VK-TURN calls, the DNSTT DNS tunnel, a standalone Telegram proxy over WARP — and olcRTC, which disguises traffic as a video call.
Most VPN clients give you one core and one way to connect. YPtun gives you a toolbox. Several censorship-bypass engines in a single app: when one method gets blocked, switch to another and keep going.
The point is versatility. Xray and sing-box with every common protocol and transport, obfuscated WireGuard via AmneziaWG, tunnelling through real calls (VK-TURN and olcRTC), the DNSTT DNS tunnel, import of basically anything, and Happ-compatible routing profiles. Kill one path — there are several more next to it.
Built for places where the internet fights back — Russia, Iran, and any country where sites vanish without warning.
What's new
- Optimization and bug fixes, new Trust Tunnel protocol in beta mode, updated kernels.
- New
- Trust Tunnel (beta) — the AdGuard Trust Tunnel VPN protocol has been added (HTTP/2 + QUIC, obfuscated to look like regular HTTPS). It can be imported as a regular config via a tt:// link (paste / QR code / file); the type is displayed as "Trust Tunnel." ⚠️ Requires Android 8+ (the client itself works with Android 6, but this protocol only works with 8).
- SSH key in automatic installation on VPS — VK-TURN / WDTT / DNSTT can now be installed not only by password but also by SSH key: insert the key manually or upload a file from your phone.
- The "Auto" button toggle on the main screen (Settings → app) allows you to hide the round button for quick server selection.
- Disable battery optimization is a new option in the settings to prevent the VPN from dropping in the background during long (24 hours+) sessions.
- Fixes
- AmneziaWG / Full UDP tunnels are reconnected - sing-box 1.13 removed legacy inbound fields, which caused the configuration to crash on engine startup (the tunnel was up, but sing-box was not).
- Xhttp ping in proxy GET/HEAD mode - domain-fronting configurations no longer show a false "unavailable" error (the probe sent an empty Host → the backend responded with a 400).
- DNSTT ping in proxy GET/HEAD no longer immediately fails—an obfuscated DNS tunnel cannot be verified with an X-ray probe; it now shows "-" when not measured.
- Cold start—the list immediately shows the actual configuration information (protocol · server), without the "Proxy" display for a few seconds.
- Equal tiles in two-column mode; updating a single subscription from the "⋮" menu; Telegram proxy buttons without clipping.
- Kernels
- Updated vendor olcRTC, WDTT (VK-TURN kernel refactor), and freeturn (VK-TURN).
