LEA Extended Input

LEA Extended Input lets users send keyboard and joystick inputs from Android or iOS client devices to a PC. The standalone server, which runs on 64-bit editions of Windows 7 and higher, emulates four joysticks and one keyboard and can redirect gamepad and joystick inputs to them. Users can connect multiple clients to one PC, with client statuses synchronized. Controls can be selected from 13 standard options, created from scratch, or imported from the community. Users can adjust controls by shape, size, orientation, color, and texture, and use the client macro editor to create macros. In Extended mode, a compatible PC game can send information such as inventory, a mini-map, or radar to the client interface. Users can export projects through LEA Resources Manager on PC for community sharing. The maker offers a C# SDK and lists a C++ SDK as available soon. The clients and server are free; mobile clients are listed in the App Store and Google Play.

LEA Extended Input pairs mobile clients with a Windows server for keyboard and joystick emulation. Its custom controls, macros, and multi-client support are useful for configurable setups.

LEA Extended Input suits PC players who want to configure Android or iOS devices as input clients. It also fits users who want to build, customize, or share control layouts.

LEA Extended Input turns an Android or iOS device into a configurable input surface for a Windows PC. It is best for players who want to design touch controls, build macros, or connect multiple mobile clients to one computer. Its strongest draw is that the clients and server are free; its main constraint is that it depends on a Windows server.

Overview

LEA routes keyboard and joystick emulation from mobile clients through a standalone PC server. The server emulates up to four joysticks and one keyboard, and can redirect gamepad and joystick inputs to them. That capacity suits a configurable gaming station, but LEA is less compelling for someone seeking a mobile-only controller or a setup without a Windows PC.

Key features

Custom controls and macros

Users can start with 13 standard controls, create their own, or import community-shared controls. Each control can be changed by shape, size, orientation, color, and texture, making LEA useful when a game needs a bespoke touch layout rather than a fixed on-screen pad. A client-side macro editor adds another layer of input configuration.

Multi-client and extended mode

Multiple clients can connect to one PC, and LEA synchronizes their statuses. That makes it a better fit for setups with more than one mobile controller than software limited to a single client. In extended mode, compatible PC games can send information such as inventory, a mini-map, or radar to the client interface; the benefit depends on the game supporting LEA.

Sharing and development

Projects can be exported through LEA Resources Manager on PC for community sharing. The maker offers a C# SDK, with a C++ SDK described as available soon. These options make LEA more adaptable for users interested in custom integrations, while the current SDK offering is C#.

Pricing

LEA is freemium, with a Free plan at no cost. Both clients and server are free, so the core mobile-to-PC arrangement does not require a paid tier. That is a strong fit for budget-conscious users who want custom controls and multi-client support; there is no cheaper tier that gives up features, and no paid plan to compare.

Platforms

Mobile clients are available for Android and iOS, while the server runs on 64-bit editions of Windows 7 and higher. The platform combination fits users pairing a phone or tablet with a Windows PC, but not someone who needs the server on macOS or Linux. Keyboard and mouse output, virtual-controller output, profile switching, and per-app profiles are supported; controller inputs include gamepads, joysticks, and touchscreen controls.

Who it's for

LEA makes sense for PC players who want to tailor touch controls to a game, create macros, share layouts, or connect multiple mobile clients. Its C# SDK and extended mode also suit users working with PC games that can communicate with LEA. It is a poor fit for users who want a standalone mobile solution or need a server outside the supported Windows environment.

Pros and cons

• Pros: Free clients and server remove a direct cost barrier; customizable controls and macros accommodate tailored input layouts; up to four joysticks, one keyboard, and multiple clients support more elaborate setups.
• Cons: The server requires 64-bit Windows 7 or higher, ruling out other desktop server platforms; extended-mode displays rely on compatible PC games; the offered SDK is C#, while C++ is not yet available.

Alternatives

Verdict

Choose LEA Extended Input if you want a free, configurable mobile input system for a Windows gaming PC, especially when custom layouts, macros, or multiple clients matter. Look elsewhere if you need a non-Windows server or a controller solution that does not depend on a PC-side setup.
