Treadphone

Treadphone is a Windows desktop app that turns your phone into a wireless PC touchpad. You run the .exe on your PC, scan a QR code with your phone's camera, and your phone screen becomes a trackpad — tap, scroll, drag, and right-click just like a physical touchpad.

What sets it apart:

• No phone app — works entirely through the phone's browser via QR code scan
• No account or signup — no registration, no login, no profile
• No user data collected — privacy-first by design; nothing is stored or transmitted beyond the session
• No subscription — simple $1.49/24hr pay-as-you-go pricing
• Instant setup — scan and go, nothing to install on the phone side

It's built as an independent/indie project with direct developer support.
