Introducing

CoolHinge

The most advanced hinge audio experience ever created for a problem that doesn't exist.

Creak Engine

A sound so real, you'll check the warranty.

Continuous creak mode maps audio intensity to hinge velocity at 60Hz. Spacecraft-grade engineering, squeaky-laptop-grade purpose.

Menu Bar Native

Lives in your menu bar showing your hinge angle in real time. A speedometer for the least important metric on your computer.

Undocumented Sensor

A hidden HID sensor reports the exact hinge angle. Apple never documented it. We built an entire app on it.

Six pro sound profiles. Zero pro use cases.

Creak

Organic. Alarming.

Grind

Submarine hatch.

Click

Rhythmic. Pointless.

Splinter

Destruction vibes.

Pipe

Haunted plumbing.

Squeak

Unprovoked. Perfect.

Free. Local. No account. No cloud. No reason.

Requires macOS 14+. A MacBook with a hinge. Questionable judgment.
