For those App Store screenshots that will never match the phone corners...

No-fuss match for Apple's corners!

The app is very easy to you. However, it is completely a one trick pony. You cannot adjust the size or the corner radius. And the "border" option is a joke. On or off. No change of color. It DOES round the cornors, but you may not like the (only) size in the result.

I am so happy this app was built. I've needed something like this for years and though it's a single and simple action, I had to take tedius steps in Adobe Illustrator, which was time-consuming. I've also interacted with the developer who was sup responsive and helpful.
