DimmerPro — Screen Dimmer

DimmerPro is built for developers and designers who work late, traders and analysts running multi-monitor setups, and anyone sensitive to bright light. When even your hardware's lowest brightness setting still feels too bright and your eyes are paying the price, DimmerPro dims further — entirely in software, easing eye strain without giving up screen comfort.

Darken every display independently or in sync, save your favorite levels as presets, and let the built-in scheduler switch modes automatically at set times. A global keyboard shortcut adjusts brightness instantly from any app — all from a lightweight menu bar icon that never touches your Dock.

DimmerPro is built natively with SwiftUI and runs at close to 0% CPU in the background — unlike heavier, cross-platform dimmer apps that quietly drain your battery. It's the lightest way to keep every screen comfortable, all day.

DimmerPro uses next to no CPU, collects no personal data, and makes no network connections — fully sandboxed for the Mac App Store. Note: due to macOS system restrictions, dimming the lock screen isn't possible.

Core dimming is completely free, forever. New installs also get a full 3-day Pro trial that unlocks multi-display sync, the scheduler, up to 4 presets, and the global keyboard shortcut; after the trial, DimmerPro Pro is a single $1.99 payment — pay once, own it forever, no subscription.
