A kippa (yarmulke) is the head covering worn by Jewish men. I kept forgetting mine, so I built an app that draws one on the iPhone screen — edge to edge, brightness pinned, so you can rest the phone on your head. Tap it and it says Amen. Seven styles, plus a designer: material, panels, colour, and text embroidered around the rim, which curves and reads right to left in Hebrew. Drawn live in SwiftUI Canvas, not bitmaps. No account, no tracking, no network. It is a joke, and it says so.
