What this utility does
LidAngleSensor is a small, free macOS program that continuously reports the hinge position of your laptop in degrees. It draws a live numeric readout so you can see exactly how far the display is open at any moment — useful when you need consistent screen tilt for viewing or posture.
Real-time feedback plus a sound cue
Along with the instant angle display, the app can emit a creaking-like sound when the lid crosses a preset threshold. This audible indicator adds a tactile cue to the visual readout, helping you notice when the screen reaches a particular position without staring at the display.
Who should use it
- People who adjust screen tilt frequently for better sightlines or to reduce glare
- Users arranging ergonomic setups who want repeatable lid positions
- Anyone who prefers an easy, nontechnical way to monitor their Mac’s lid angle
Simple layout and accessibility
The interface is intentionally straightforward so even those unfamiliar with utilities can operate it. Controls and indicators are clear, letting you check the current angle and hear the alert without digging through complex settings.
