FOLD / WINDOWS + ANDROID
A second screen. Already in your hands.
Turn an Android phone or tablet into a second monitor for your Windows 11 PC. FOLD extends your desktop over USB or trusted local Wi-Fi, with optional touch control. Move a window onto the extra display instead of duplicating your main screen.

BUILT FOR THE EVERYDAY SETUP
One useful job. A few ways to do it.
02
USB or local Wi-Fi
Choose an ADB USB connection or trusted local Wi-Fi. There is no FOLD account or cloud relay.
03
Touch when you need it
Enable optional touch input on the host to control the virtual display from Android. A 30 FPS limiter is available.
BEFORE YOU DOWNLOAD
Check your setup.
Install both halves of the product. The Android app does not replace the Windows companion.
- Windows 11 x64 is the only supported Windows platform. Windows 10 is outside the support scope.
- Android 8.0 (API 26) or newer; no root required.
- The matching FOLD Windows host and Android app from an official release.
- A data-capable USB cable, or access to the same trusted private network.
Phones and tablets use the same client. Connection and portrait/landscape streaming have been tested on a TECNO CM5 phone and selected tablets, not every Android model. A tablet provides more usable desktop space. If a phone keyboard obscures the Wi-Fi IP field in landscape, enter the address in portrait.
FROM DOWNLOAD TO CONNECTED
Make the first connection.
Follow our step-by-step FOLD setup guide, with an ID / EN language choice, or use the official instructions for your release.
Full setup documentation ↗- Download the Windows installer and matching Android APK from the official release. Verify the published SHA-256 checksums before installing.

- For USB, enable USB debugging, connect the device, and approve the PC fingerprint. Choose USB and select the intended Android device on Windows.
- For Wi-Fi, connect to the same trusted private network. Select Wi-Fi and enter the PC IP shown by the Windows host into Android.
- Press START on Windows, then CONNECT on Android. Use Extend in Windows Display settings and move a window onto FOLD Display. Enable touch on the host if wanted.
GOOD TO KNOW
Before you ask.
Is FOLD screen mirroring?
No. FOLD creates a separate Windows virtual monitor. Move a window onto that display to see it on Android. It does not cast the Android screen to the PC.
Will any USB-C cable turn my phone into a monitor?
No. This is an app-based USB/ADB connection, not HDMI or USB-C video input. Install the Windows host and Android app and use a cable that supports data.
Is FOLD free or open source?
The current product is proprietary freeware: free to use under its EULA, without an account, subscription, or advertising. The public repository provides documentation and official downloads.
Does FOLD support a Mac, Linux PC, or iPad?
The supported host is Windows 11 x64 and the client is Android. Windows 10, Linux, macOS, and iPadOS are outside the support scope.
