Gradiance empowers you to design elegant gradient backgrounds that can be utilized as wallpapers for your macOS, iOS, and iPadOS devices. The entire screen becomes your canvas. The app has been meticulously crafted to provide an intuitive user-friendly interface. Its design prioritizes simplicity and compactness, ensuring minimal interference. You can effortlessly conceal the controls with a simple click or tap and adjust the position on the screen. Creating a gradient is as easy as 1-2-3! Begin by setting the desired number of control points across the width and height of your screen. Gradiance automatically generates evenly spaced points and randomly assigns colors to each one. Then, you can experiment and have fun selecting each control point you wish to modify, alter its color and opacity, and adjust its horizontal and vertical position to achieve visually appealing gradient effects. Finally, you can now import and export your gradient settings. When you have a design you are happy with you can save it to a png file (on macOS) or export it to Photos to assign as your wallpaper. The image is automatically optimized for the size and resolution of your screen.
