Flux adds real-time haptic feedback to your entire Windows experience. Every button, link, slider, and tab you hover over or click, you feel it through your Logitech MX Master 4's haptic motor. It detects UI elements across every app at 100Hz, with different waveforms for hover enter, hover exit, link hover, and click, all customizable. 7-day free trial, no account needed. $2.99/month with rent-to-buy.
Hey everyone! I'm the solo developer behind Flux. Started building this on January 5th and launched v1.0 on March 1st.
The MX Master 4 has a great haptic motor that's barely used outside of the Actions Ring. I wanted to turn it into something you feel constantly, every hover, every click, across every app.
Under the hood it's a background service using Windows UIAutomation at 100Hz, classifying what's under your cursor, and firing waveforms through a Loupedeck plugin pipeline. It drops to 2Hz when idle so it barely touches your CPU.
Would love feedback on what waveforms or behaviors you'd want next. v1.1 is already in the works.
