Acorn (software) explained
Acorn is a raster graphic editor for macOS developed by August Mueller of Flying Meat Inc, based out of Mukilteo, Washington, United States. Acorn was first released on September 10, 2007[1] and was built upon the framework of a previous image editing application of Flying Meat Inc., FlySketch.[2]
Acorn makes extensive use of Apple's Core Image framework for its image processing.[3] [4] The native file format of Acorn is .acorn.
