Gradiance

Gradiance does one thing, and does it well: designs gradients. Whether you need a striking image to use in your designs, or the source code to display the gradient on a web page, in a Mac app or an iOS app, Gradiance is there to save you time.

You can design your own, or automatically create one by extracting the colours from a photo. You can create gradients in a variety of shapes and styles — linear, radial, or angular, looped or bounced up to ten times. You can even blend your gradient with a photo to create special effects, such as vignettes or vintage processing.

When you're done, bookmark it, save the resulting image back out to the photo library, share your gradient as a link via email or Twitter, or create a "Gradient ID Card", a handy reference card that includes the gradient colour values and a special code that can be scanned* to load the gradient, allowing you to share your gradients via photo-sharing sites or even in print.

* Requires "QR Code" scanning software, not included.
