Desktop recommended
Heads up! You can use the Icon Designer on mobile, but it's definitely not made for it. Managing a library of 400+ icons is just a massive job for such a tiny screen. You'll have a much better time on a desktop! <3 P.S.: On some mobile devices, shadows with higher blur values may look blocky in exported icons. This has been observed on iOS and is a limitation in the rendering method. Desktop browsers render the same blur smoothly.
