Free for Android and Windows
Combine Wi-Fi and mobile data, using your own V2Ray configs
V2Duo puts every internet connection you have to work at the same time and spreads your V2Ray and Xray configs across them. Downloads and video get faster, and when one connection or config drops, you stay online.
- No sign-up, no personal data collected
- Light: under 1% CPU when idle
- VLESS, VMess, Trojan, Shadowsocks and Hysteria2
Three steps to a faster connection
- 1
Add your configs
Paste a config or subscription link, scan a QR code, or import a Clash or sing-box file. You can also skip configs and just combine your connections.
- 2
Turn on your connections
Keep Wi-Fi and mobile data on together. On Windows, cable, Wi-Fi and USB tethering from your phone can all work side by side.
- 3
Connect
V2Duo spreads connections across every path, drops the broken ones, and the Speed lab shows how much combining really helped.
Everything V2Duo does
Each feature has its own full guide: what it does, where it helps and where it does not.
Combine Wi-Fi and Mobile Data on Android and Windows
Put Wi-Fi, mobile data, cable and USB tethering to work at the same time, so downloads and video get faster and one dropped connection does not knock you offline.

Numbers we measured ourselves
Every V2Duo release is tested on real machines before it ships: CPU and memory use, traffic throughput, and how the app behaves when a connection drops and comes back.
An honest note too: combining two connections does not exactly double your speed. At best it adds the speed of the slower one, and you notice it most in multi-part downloads, video and heavy pages.
See the Speed lab- CPU when idle
- 0.2%Windows, two connections, four configs
- Memory used
- 77 MBWindows service, same test
- Data cap per speed test
- 15 MBthe test stops as soon as speed is steady
- moved in 1.5 seconds
- 381 MBon a test server, so the app itself is not the bottleneck
Where does V2Duo make the biggest difference?
Combining helps most with anything that opens several connections at once.
Where you will feel it
- Download managers like IDM or ADM that fetch files in parts
- YouTube and high-quality video
- App and game updates from the store
- Heavy pages full of images and video
- When one of your connections keeps dropping
Where it cannot do magic
- A single-connection download from one server: it is limited to one path
- Online gaming and ping: combining does not lower ping
- Voice and video calls: better kept on one stable path
- A slow config: you cannot go faster than its server

Frequently asked questions
Is V2Duo a VPN service?
V2Duo does not sell servers or configs. It is a client that works with your own V2Ray and Xray configs and can combine several internet connections. Without a config it can still combine connections or change your DNS.
Will my speed double?
Not always. At best, the speed of your slower connection is added to the faster one. The effect is biggest in multi-part downloads and video. The Speed lab inside the app shows the real number for your own connections.
Which devices does it run on?
Android 7 or newer, and Windows 10 and 11 (64-bit). On Windows you can use cable, Wi-Fi and USB tethering from your phone together.
Do I need an account?
No. The app has no accounts and collects no personal data. Even buying the ad-free plan works without an email.
Which configs are supported?
VLESS (including Reality), VMess, Trojan, Shadowsocks and Hysteria2 links, subscription links, Clash and Mihomo files, sing-box configs and Xray outbound JSON. TUIC and WireGuard are not supported.
What does the ad-free plan add?
It removes every ad. No feature is locked behind payment; the plan is for people who do not want ads and want to support further development.
