LEA Extended Input

LEA Extended Input is a mobile client and PC server for emulating keyboard and joystick inputs. It suits players who want to build custom touchscreen layouts, use macros, or connect multiple clients to one PC. Its free client-and-server setup is a strong draw, but the Windows server and compatible-game requirements make it a focused choice.

Overview

LEA turns Android and iOS devices into configurable input surfaces for a PC. Its standalone server emulates four joysticks and one keyboard, and can redirect gamepad and joystick inputs to them. That gives a multi-device gaming setup room to grow, but it is not a fit for someone who wants a mobile-only controller or cannot run the server on Windows.

Key features

Custom controls and macros

Users can choose from 13 standard controls, create their own, or import community-shared controls. Shape, size, orientation, color, and texture are adjustable, so the layout can be tailored to a game or screen rather than limited to a fixed virtual pad. The client’s macro editor adds another way to configure input; users can also switch profiles and keep profiles per app.

Multi-client and extended mode

Multiple clients can connect to one PC, with their statuses synchronized. Extended mode lets compatible PC games send information to the client interface, including an inventory, mini-map, or radar. That can make a phone useful as more than a control surface, but it depends on game support for LEA.

Sharing and development

Projects can be exported through LEA Resources Manager on PC for community sharing. The maker offers a C# SDK, while its C++ SDK is listed as available soon. Tutorials cover basic and advanced functions on the maker’s YouTube channel, and a user forum is also available.

Pricing

The free plan covers both the mobile clients and server, so there is no paid tier to weigh against the core setup. It is the straightforward choice for players willing to use the Windows server and check whether their games support the features they want.

Platforms

Mobile clients are available for Android and iOS, with the server available for 64-bit editions of Windows 7 and higher. LEA is therefore multiplatform across those devices, but the PC side is specifically Windows rather than a Linux or macOS server.

Who it's for

LEA is best for players who want extensive control over touchscreen layouts, macro creation, per-app profiles, or several mobile clients connected to one PC. Community imports and project exports may also appeal to users who want to share customized layouts. Look elsewhere if you need a server outside Windows or rely on Extended mode in a game that does not support LEA.

Pros and cons

Pros

• Free clients and server: the full client-server arrangement costs nothing.
• Flexible layouts: 13 standard controls, custom controls, community imports, and appearance adjustments give users room to tailor touchscreen input.
• Room for multi-device setups: the server emulates four joysticks and one keyboard, and supports multiple clients on one PC.
• Beyond basic input: macros, per-app profiles, and compatible-game information in Extended mode add useful configuration options.

Cons

• Windows server dependency: the server requires a 64-bit Windows 7-or-higher edition, ruling out a PC setup without Windows.
• Extended mode depends on game support: its client-side inventory, map, or radar display is useful only with a PC game that supports LEA.
• PC-oriented setup: mobile clients alone do not provide the keyboard and joystick emulation; the standalone server is central to the product.

Alternatives

For a broader shortlist, browse Game Controller Mapper Software. Choose GameFlow instead if you want a free, open-source beta with Windows, Linux, and macOS archives. AntiMicroX is a free GPL v3 desktop application for Linux and Windows, making it a more suitable direction for a desktop-focused setup. Consider Monect PC Remote Play when core PC remote-control features across Android, iOS, macOS, web, or Windows better match your needs; its Premium plan is for ad-free use and higher feature limits, with custom pricing.

ControllerBuddy, JoyShockMapper, OmniControl, PadForge, and PlayAbility Adaptive Software are other options to compare.

Verdict

Choose LEA Extended Input if you want a free, highly configurable mobile control surface for a Windows PC, particularly for multi-client play or custom touch layouts. Its main advantage is the breadth of input and layout options without a client or server charge. Look elsewhere if you need a non-Windows server or your games cannot use LEA’s Extended mode.
