  • •Lifetime pricing at $7.99/$19.99 is fair for one-time purchase
Weaknesses
  • •macOS-only limits addressable market; Windows/Linux users have no equivalent from this vendor
  • •Similar focus-isolation UX exists in Rectangle, Focus, and countless free alternatives

Blur Reveal Input – CSS blur for password fields (hover/touch)

The input shows the actual characters behind a CSS blur and exposes them via a hover or touch-and-drag reveal window with a smooth fade-out. It's zero-dependency and tiny (~7KB minzip), plugs into any framework or via CDN, and even honors prefers-reduced-motion and screen readers. Clever UI craft for polish-hungry teams, but it's primarily a cosmetic enhancement that doesn't alter underlying security concerns.
