Pixite continues its string of clever iOS image tweaking tools—following Tangent and Fragment—with Union, a compositing app that moves away from shape-based blending and instead approaches the process in a more conventional manner. Union is designed to combine images by knocking out specific colors as transparent, while borrowing some mojo from the company’s previous apps, and it’s a pretty slick affair—but still lacking some key features for optimum image blending.
Every time a new photo effects app pops up, it’s often frustrating to see the same sepia toning filters, blur effects, and other reliable features that are all getting rather long in the tooth. This fact makes the appearance of Fragment all the more exciting, as it produces effects that nothing else in the App Store even attempts to mimic, yet remains exceedingly easy to use and explore. The app lets you choose from one of 46 built-in base effects, which are essentially distortion masks based on a variety of shape combinations, from simple frames to abstract designs – including crystal shards, geometric patterns, and circular constructs – which distort the image in any number of ways.
