🚧 Beta program open

Help shape the app for lighting techs.

I'm a lighting technician, and over the years I got tired of switching between five different apps just to check a network, browse a fixture manual, or send a quick DMX test signal from my phone. So I built the tool I actually wanted to have in my back pocket on a job.

The beta program is expected to begin in Q3/Q4 2026. Limited spots, free during beta — being selected for the beta doesn't guarantee free access once the app launches.
