Dim beyond macOS limits. Warm your screen at sunset.
Smart breaks that know when you're working.
One slider unifies system brightness and gamma dimming. Go below macOS minimum — all the way to a completely dark screen.
Warm your screen gradually at sunset. Dimly shifts color temperature to reduce blue light exposure when it matters most.
Gentle 20-20-20 reminders that detect your activity. Dimly pauses when you step away and resumes when you're back.
Remove the dopamine triggers. Toggle system-wide grayscale instantly from your menu bar.
