Reading in bed
The pages go warm while the rest of the screen stays as it is.
Night Light
A blue light filter that lives in the browser
Pages warm up in the evening the way a lamp does — you set how much and from when, and it applies where you say, not to the whole machine.

click the toggle — this is the real interface, not a screenshot
System night light warms everything at once, including the photo you are editing. And it lives three settings screens away, so it gets switched on in January and forgotten by March.
How it works
Warm, not orange
The filter takes blue out of the colour, it does not paint a sheet of amber over the page.
01
Set the warmth
One slider, and the page changes while you drag it. Forty-five per cent is where most people stop.
02
Give it evening hours
From 20:00 to 07:00 by default, because that is the point of the mode. Scheduling is part of Pro.
03
Choose where it applies
Everywhere, or everywhere except the sites where colour matters — your own list, separate from every other mode.
What you get
What makes it its own mode
Separate from dark mode
Dark theme is for all day, warmth is for the evening. Sharing one schedule between them meant one silently switching the other off.
free
Works on white pages too
A colour matrix reduces the blue channel, so even a pure white background goes warm — a sepia tint cannot do that.

Its own site list
Ten sites on the free plan, and they are not shared with blocking or dark mode.

Live slider
The page responds as you drag, so you pick a number you can actually read at.

Evening schedule
On at sunset, off in the morning, without touching it. Part of Pro.

Common cases
Where a browser filter beats a system one
Editing photos in the evening
Put the editor on the exception list and colour stays true where it matters.
A work laptop you cannot change settings on
The filter is in the extension, not in the operating system.
Two hours before sleep
Warmth on a schedule at the hour the reading actually happens.
Dark theme is not enough
Dark backgrounds still send blue through the text. Warmth changes the colour itself.
Eyes tired by the evening
Pair it with eye exercises and the 20-20-20 timer from the Eyes mode.
What the filter reads
It changes how the page is drawn in your browser and reads nothing about what is on it. The list of sites you gave it stays on your device.

About Night Light
How is this different from dark mode?
Dark mode changes the colours of the interface. The blue light filter changes the temperature of everything on screen. They work together and each has its own schedule.
Does it work on white pages?
Yes. The filter reduces the blue channel of the colour itself, which is why plain white turns warm rather than staying white.
Do I have to schedule it?
No. You can switch it on by hand for free. The schedule comes with Pro.
Will it warm images too?
Yes — that is the point of a light filter. Sites where colour matters can go on the exception list.
Night Light is one of twelve
It comes with dark mode, blocking, focus sessions, screen time and eye care — free.
