The open-source control center for Windows handheld gaming. Map any gamepad, add gyro, tune power and launch the right profile on ROG Ally, Steam Deck, Legion Go and more.
One app, the whole handheld
Handheld Companion brings the controls you reach for most into one touch-first interface—before the game, during it and for every title after.
Gamepad mapper
Remap controller buttons to keyboard, mouse, joystick or trigger actions. Adjust deadzones and swap between virtual Xbox 360 and DualShock 4 output without rebuilding your whole setup.
Explore controller mapping →Gyro controller for PC
Universal motion controls turn the built-in IMU into precise input for first-person, third-person, racing and emulated games.
Auto TDP & QuickTools
Tune TDP, frame limits, refresh rate, resolution, brightness, volume and power mode from an overlay designed for small screens.
Automatic game profiles
Detect the active title and apply its controller layout, motion, graphics and power preferences automatically.
Real interface screenshots
Explore all 12 parts of the Handheld Companion workflow — from the touch-first library to controller mapping, gyro, Auto TDP and the in-game performance overlay.
Browse installed games from a large, touch-friendly library built for a handheld screen. Artwork, titles and launch actions stay clear without dropping back to the Windows desktop.
Give every game its own controller, power and motion setup. Handheld Companion can load the right profile when a title becomes active, then return to your global defaults afterward.
Choose how Windows and your games see the physical controls. Configure a virtual Xbox 360 or DualShock 4 controller and shape the input path for broader compatibility.
Put common handheld actions behind the buttons already under your thumbs. Open QuickTools, switch controller modes, change volume or launch an application with combinations you define.
Reach essential Windows handheld controls without leaving the game. The compact QuickTools panel keeps display, connectivity and everyday device settings one button away.
Balance performance, thermals and battery life from the same overlay. Set a manual power target or let Auto TDP react to the frame-rate goal while you play.
See and adjust the active game profile from QuickTools. Power presets, motion controls and graphics choices stay connected to the title you are actually playing.
Open favourite games and utilities from a controller-friendly applications panel. Running processes and launch shortcuts remain accessible while the desktop stays out of the way.
Watch the metrics that matter while a game is running. The performance overlay surfaces frame rate and live CPU or GPU information so power changes have visible feedback.
Inspect a live three-dimensional DualSense model while configuring controller input. It gives button, stick and trigger testing a clear visual reference before launching a game.
Use a device-specific Steam Deck model to understand the active control state on Windows. The visual layout makes testing the handheld's distinctive inputs easier.
Turn the handheld screen into a virtual DualShock 4-style touchpad for PlayStation Remote Play. Touch and controller workflows can stay together on the same Windows device.
