Lex: Advanced Low-Latency Remote Control System

The Story of Lex: When the Phone Becomes the Ultimate Power to Control PCs

Have you ever found yourself in such funny yet awkward situations?

• Curling up in a warm blanket watching a movie, and when it's over, you have to get up just to click the mouse and switch to the next episode.
• Your friends come over to play fun games on the computer, but after searching the whole house, you can only find one controller. Are you all just going to sit and stare at each other?
• Going to present in front of a crowd, but the presentation remote suddenly runs out of battery or the buttons are acting up, interrupting your presentation.

We have also been in those situations and tried looking for remote control applications for computers on our phones. The results were just frustrating: lagging mouse movements, inconsistent button responses, complicated connections, and annoying ads.

That's why we created Lex - an app that helps you turn your smartphone into a powerful, smooth, and zero-latency PC controller.

Experience Lex: Simple, Fast, and Convenient

To use Lex, you don't need to be a tech expert. Everything works amazingly simply:

1. Start the server on the computer: A super cool black screen will pop up showing connection information and a secure QR code.
2. Scan and Connect: Use your phone to scan the QR code. Instantly, the control interface will appear on your phone's screen as a premium web app without needing to install any applications from the App Store or CH Play.
3. Enjoy: Your phone is now a super-sensitive touchpad, an additional keyboard, or a professional Xbox game controller.

The Features That Make Lex Stand Out

• Zero Delay: The feeling of moving the mouse on your phone and seeing the cursor on the computer react instantly is an incredibly satisfying experience. Lex optimizes the connection to completely eliminate latency, making every swipe, tap, and click feel responsive as if you're using a real mouse.
• Turn your phone into an Xbox game controller (Support for 4 players simultaneously): This is the best feature for gatherings! Lex accurately simulates the Xbox game controller. Your phone will have all the buttons and ultra-sensitive analog sticks. Notably, Lex supports simultaneous connections for up to 4 phones, allowing you and your friends to enjoy family multiplayer games on PC without spending money on multiple physical controllers.
• Smoothly hold game keys: Unlike regular applications that only allow single key presses, Lex allows you to press and hold keys continuously on your phone (for example, holding a key for a character to run straight or accelerate in a race) perfectly like on a real computer keyboard.
• Absolute Security & Safe Connection: Lex operates entirely within your home Wi-Fi network and does not send any data out to the Internet. The randomly generated security key encoded in the QR Code ensures that only your device has the authority to control the computer, providing complete safety from any intrusion risks.
• Automatic upgrades with just one click: Whenever Lex has a new feature or improvement, you'll receive notifications right on your phone screen. Just press the "Update & Restart" button, and the system on the computer will automatically download the latest version, self-upgrade, and restart within seconds without requiring you to perform any complicated actions.

Who Is Lex Made For?

• Convenience lovers: Want to control the computer to watch movies, listen to music remotely while lying down on the bed or sofa.
• Gamers: Want to play co-op PC games with friends and family anytime without having physical controllers available.
• Office workers & Presenters: Want to turn your phone into a wireless touchpad and a professional slide clicker while standing at the podium.
