A reading lamp,
inside your Mac.
Lumen turns your Mac into a quiet reading light, with a timer that stays out of your way.
macOS 14+
Read without
another lamp.
Lumen uses the display you already have. Drag across the light to set its level, then tune its warmth to the page.
Pomodoro, without
the noise.
One clear number. Focus, short break, long break. The timer supports the reading without turning it into a project.
Lumen is a
reading lamp first.
A focus timer
when you need it.
Native macOS. Runs quietly. The light works independently from the timer, so the room never has to know what you are doing.
No subscription.
Buy Lumen once and keep it.
One-time purchase
Keep a little
light close.
One quiet tool for reading, focus, and the hours that belong to you.

A few answers
Good to know.
What is Lumen?
Lumen turns your Mac into a warm reading light with a minimal focus timer.
Does the light work without the timer?
Yes. The reading light works independently, so you can leave the timer paused or never start it.
Can I adjust the light?
Yes. Adjust brightness directly on the light, choose a warmth between 2700K and 3000K, and position or resize the bar to suit your desk.
Does Lumen work on every Mac?
Lumen is being built for Macs running macOS 14 or later. Hardware compatibility details will be published before release.
Is Lumen a subscription?
No. Lumen will use a one-time purchase. Buy it once and keep it.
Does Lumen collect my data?
Lumen only asks for Google sign-in when you buy or manage premium access. We store your verified email, purchase status, and up to two device sessions. Timer and lamp preferences stay on your Mac. Read the Privacy Policy for details.
Does it hurt my MacBook?
No. Lumen only uses the display to show the reading light and does not change or control MacBook hardware. macOS continues to manage brightness, temperature, and battery use.
