A $0.99 Mac utility reads the laptop’s hinge angle and turns closing the screen into a live freeze, tilt, blur, and fade.

Landing page captured for the 2026-09-16 issue.

Field notes

DuoFold uses a MacBook’s hinge-angle sensor as the control input for a short closing-screen animation. The page describes 60 Hz angle readings, local GPU processing, and four visual-style options including a depth effect. Compatibility is model-specific: recent 14-inch and 16-inch MacBook Pro models are listed, while some MacBook Air machines may fail to expose the sensor and should be tested during the one-day trial. The app requires macOS 14 or later and separate Apple-silicon or Intel downloads.
