A huge gift to the product design world from Australian app developer Bjango. Founder Marc Edwards and his team have produced this shockingly detailed and well-documented set of app icon templates for Photoshop, Illustrator, Sketch, and Affinity Designer.

The templates cover Android, iOS, OS X, Apple TV (tvOS), Apple Watch (watchOS), Windows, Windows Phone and web favicons. Where possible, they’re set up to automate exporting final production assets.

The cherry on top is that the whole kit is free and open source, released under the BSD license. You can find out more and download it at bjango.com.
