Light off? One click on
Your light is off... One click, it's on — with your last-used settings.
What it does
psst, this page acts as your light: click 🌑 to switch it on, 💡 to open the preset menu.
Light on? One click to presets
While it's on, the click lets you pick your favorite preset.
Why you'll keep it
Wakes when your Mac does
Off when your Mac sleeps, back on when you return — the wake half is what even Elgato's own app doesn't do.
Day and night on schedule
Bright light until 19:00, chill mode after — your presets switch by time of day, on their own.
Set it and forget it
Flip Start At Login in the 💡 menu and it's in your menu bar from the first boot — no Login Items fiddling in System Settings.
Invisible by design
No Dock icon, no companion windows, no dependencies. If it weren't for the 💡 in your menu bar, you'd forget it exists.
Presets, built in-app
Seven sensible presets ship with it — Meet, Work, Bright, Cold, Warm, Night, Chill — and a tiny editor for your own. No config files, no terminal.
Always in sync
Change the light from Elgato's app or its physical controls — the icon keeps up with the real state, not just its own.
Zero setup
It finds your light by itself; on stubborn networks it scans for it anyway. And it never pretends to control a light it can't reach.
Tiny and private
One Swift file, zero dependencies, and it talks only to your light over your local network. Nothing leaves your house.
The real thing
Everything you just tried, on your Mac: control your light, define and schedule presets, automatic wake-up — all in a single menu bar icon.
