Squircle
A genuinely smooth rounded rectangle, applied straight to a shape layer.
A rounded rectangle whose curvature actually changes smoothly.
A preset that builds a squircle — a smooth rounded rectangle.
Unlike an ordinary rounded rectangle, a squircle inserts a curve of smoothly changing curvature between the constant-curvature arc and the straight edge, which makes the corner read as genuinely smooth.
