Dim your screen below hardware limits.
DimmerPro is a native macOS menu bar app for developers and designers who work late, traders running multi-monitor setups, and anyone sensitive to bright light. When your display's lowest brightness still feels too bright, DimmerPro dims further — entirely in software.
Core dimming is free, forever. No account, no ads, no tracking.
Built for people who stare at screens all day
Not a generic brightness slider — DimmerPro is shaped around three specific ways people actually use it.
Night owls
Developers and designers coding or designing late — dim well past your display's hardware floor without straining your eyes.
Multi-monitor traders
Traders and analysts running several displays keep every screen synced to the same comfortable brightness, or tuned independently.
Light-sensitive users
If bright screens trigger eye strain or headaches, DimmerPro's sub-zero dimming gives you a lower floor than macOS allows on its own.
Everything you need, nothing you don't
Core dimming is free forever. A handful of power-user features are part of DimmerPro Pro.
Sub-Zero Dimming
Dim past your hardware's own brightness floor, from a one-click menu bar slider.
Multi-Display Sync
Darken every display independently, or keep them all in sync with one control.
Auto Scheduler
Set a time range and let DimmerPro switch modes automatically — no manual toggling.
Up to 4 Presets
Save your favorite brightness levels with an emoji and a name, and switch in one click.
Global Hotkey
Adjust brightness instantly from any app, without opening the menu bar panel.
Built with SwiftUI
Native from the ground up — runs at close to 0% CPU in the background, unlike heavier, cross-platform dimmer apps.
Simple pricing
Unlocks multi-display sync, the scheduler, up to 4 presets, and the global hotkey. Core dimming stays free forever, with or without Pro.
