Control your ambient light straight from the menu bar — native, lightweight, and built for Skydimo and Adalight-compatible LED strips.
Cylch lives in the macOS menu bar and talks to your LED controller over a plain USB serial connection. Colour frames are generated on the Mac and streamed to the strip in a continuous loop — what you see is always the current state, never a cached scene from someone else's server.
Cylch was created specifically as a lightweight controller for Skydimo LED strips, with a focused native interface that stays out of the way.
On launch, Cylch automatically looks for a compatible serial port and attempts to connect, so in most cases the light is ready without any manual setup.
Pick a static colour or let a slow rainbow drift across the strip. Brightness and animation speed are big, friendly dials, and every change is applied live while the frames stream — no apply button, no restart.
Cylch remembers the port, the LED count, the effect, the colour, and the output levels. It can launch with macOS, reconnect to known hardware, and switch the lights off on a daily schedule when the day is done.
Cylch requires no account and does not collect your name, email, files, contacts, precise location, LED settings, colours, or serial port information. Your preferences stay on your Mac.
The app uses Google Firebase Analytics for limited usage statistics — including a simple event when an LED device connects, along with basic technical information such as the app and macOS versions. This data is used only to understand reliability and improve Cylch. It is never sold, used for advertising, or used to build a profile about you.
Circle, ring, cycle — a nod to the loop of colour frames that travels from your Mac, through the controller, and around the strip. Cylch starts with the system, keeps the cycle running quietly, and stays out of your way.
Say it roughly like “kilkh” — and finish with the same breathy ch you hear at the end of the Scottish word “loch.”
