What is Cadran?

Cadran is a unique, native macOS application designed to bring functional elegance directly to your desktop background. Unlike traditional widgets or floating windows, Cadran draws customizable clock faces directly onto the wallpaper layer. This means the clock sits seamlessly behind your icons, ensuring a clean, distraction-free workspace while providing constant time visibility across all configured Spaces and external displays.

Built for modern macOS environments (Sonoma 14.0+), Cadran prioritizes performance and privacy. It operates with a minimal energy footprint, verified to be battery-friendly, and runs discreetly from the menu bar, never cluttering your Dock. It offers a simple setup process, allowing users to pick a face, set a background, and forget about it, knowing their time display is always perfectly integrated.

Core Features for Mac Users

• Wallpaper Integration: Renders the clock directly onto the wallpaper layer, ensuring icons remain fully accessible and unobstructed.
• Multi-Monitor Support: Offers per-monitor setup, allowing users to assign different faces or styles to each connected display.
• Extensive Face Gallery: Features 6 initial categories (Numeric, Analog, Data, Abstract, Matrix, Spectrum) with 22 faces available in the Pro version, with all future faces included in the one-time purchase.
• Battery Friendly Performance: Utilizes lightweight compositing, resulting in a low energy impact verified via Activity Monitor, keeping fans quiet and battery life optimal.
• Dynamic Customization: Allows tweaking of size, position, and style. Pro users gain access to custom text/background colors and dynamic backgrounds like the 'Dynamic Sky'.
• Screen Saver Mode: Provides a full-screen clock display when the system is idle.
• Color Adaptation: Faces can automatically adapt their colors to match the underlying wallpaper, or users can select custom palettes.
• Privacy Focused: Cadran requires no user accounts, contains no analytics SDKs, and keeps all preferences locally on the Mac. Weather-aware faces optionally use Open-Meteo without sharing unnecessary data.
• Automatic Updates: Checks for and installs updates in the background with a single click, ensuring users always have the latest version.

How to Set Up Your Desktop Clock

Getting Cadran up and running takes less than a minute, focusing on simplicity and immediate integration:
