Handheld Companion review
A free Windows handheld toolkit for profiles, power controls, remapping, and overlays.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Handheld Companion is an open-source Windows application for handheld gaming PCs. It is designed for players who want one control layer for remapping, motion input, per-game profiles, overlays, and power-management settings. Supported handheld families include ASUS, Valve, Lenovo, MSI, GPD, AYANEO, AOKZOE, ONEXPLAYER, Ayn, and ZOTAC, with functionality varying by device, firmware, and sensors. Public releases are free to download, making the software a practical fit for solo users and small teams managing Windows handheld gaming workflows.
Its strongest area is the combination of game-specific automation and handheld controls. Active-title detection can apply per-game profiles, while users can configure TDP, Auto TDP, GPU, display, frame-limit, brightness, volume, and power-mode settings. Controller remapping supports keyboard, mouse, joysticks, triggers, Xbox 360, and DualShock 4 outputs. Universal motion and gyro controls work with supported IMUs or external sensors, and the touch-friendly QuickTools overlay, custom hotkeys, performance overlays, and 3D controller overlays extend control beyond a traditional gamepad utility. Steam integration and PlayStation Remote Play support add useful ecosystem fit, including DualShock 4 motion and touchpad workflows for Remote Play.
Handheld Companion is a focused choice for Windows handheld owners who want flexible gaming profiles and device controls without a paid public-release plan. Community supporters can receive early-access builds through Patreon, while community support and documentation provide the listed support channels. The main trade-off is scope: its strengths center on handheld control and gaming workflows rather than full overclocking. Windows users with compatible hardware should consider it for remapping, motion input, overlays, and power tuning; users seeking a broader platform or a dedicated full-overclocking tool should look elsewhere.
