Warmth: Blue Light Filter

Warmth is a small menu-bar utility that makes your screen warmer, on your terms.

Click the sun in your menu bar, switch Warmth on, and turn the dial from 0 to 100%. That’s it.

Warmth remembers your setting and keeps it right where you left it. No account. No setup. No tutorial.

ONE SWITCH. ONE DIAL.

• Turn Warmth on or off instantly • Adjust the dial by dragging, using the arrow keys, or with VoiceOver • Your setting stays saved across restarts and sleep • Turn it off, and your Mac’s normal colors return immediately

Warmth collects no personal data, includes no analytics, and makes no network requests of its own.

Warmth changes the appearance of your display. The percentage shown is an intensity setting, not a measurement of blue light reduction. Warmth is not a medical device and makes no health claims.
