Today I’m releasing Abendrot—the free, open-source Mac app for your circadian rhythm.

An evening screen is not just bright or uncomfortable; it is a signal to your body clock.

The deeper I went into the research, the harder it became to ignore the role light plays in the body’s daily timing, especially the blue and cyan short-wavelength light emitted by screens at night.

@AbendrotApp warms your displays around your local sunset and minimizes the specific short-wavelength, melanopic light (blue/cyan) that tricks your body clock into thinking it's still daytime.

Open-source wellness software is here 💻 + 🌇

@risingwithatlas The screen is the part people forget because it sits a foot from your face. Night Shift barely moves the short-wavelength blue that actually hits the clock. https://t.co/am1wlhJ38B
