what it does

🎨

Smart Profiles

Four built-in profiles — Work, Code, Game, Cinema — plus unlimited custom profiles. Each saves brightness, colour temperature, and refresh rate.

🎮

Auto Game Detection

Automatically switches to your Game profile when you launch a game. Detects Steam, Epic, and any fullscreen DirectX/Vulkan app. Reverts when you close it.

🌅

Ambient Mode

Colour temperature gradually shifts throughout the day following the sun's position. Warm at night, neutral at noon. Like f.lux, but better integrated.

🖥️

Multi-Monitor & Laptops

Works with any number of displays. Controls external monitors via DDC/CI and laptop screens via WMI. Any GPU — NVIDIA, AMD, Intel.

Global Hotkeys

Switch profiles instantly with Ctrl+Alt+1/2/3/4. Nudge brightness or colour temperature on the fly. Quick dim for late nights.

📱

App-Aware Switching

Recognises ~50 productivity apps out of the box — Office, VS Code, browsers, Teams, Slack — and can switch profiles to match. Add your own custom rules too.

🌍

Multi-Language

English, German, French, Spanish, and Japanese included. Simple JSON translation files make it easy for the community to add more.

🔒

Privacy-First

Everything runs locally. No telemetry, no analytics, no ads. The only network call is an optional location lookup you trigger yourself.
