It's strange to me though that people release new apps on macOS without making the icons conform to the usual shape. Makes applications stand out like a sore thumb on the Dock.
It's beautiful but from decades of experience in app development, I moved away about 10 years ago from using images as icons to insisting that all icons be vector files.
But hiring an Adobe Illustrator expert to professionally recreate the icon as a layered SVG wouldn't cost much. Well done!
