Fold Angle: Hinge Protractor
Foldable angle finder
Free · Designed for iPad. Not verified for macOS.
Fit your folding iPhone into a corner, against a door, or over a box edge, and read the angle between its two halves instantly.
Your folding iPhone already knows how far it's open. Fold Angle turns the hinge into a protractor.
Set the phone into a corner, against a door, or over the edge of a box, and read the angle between the two halves in degrees.
Tap once to hold a reading, then lift the phone away and read what it captured.
Set any angle as zero to compare two corners, or to measure how far a door swings.
A light tap every 15° and a firm one at exactly 90°, so you can feel square without looking.
Built for iPhone Duo. On other iPhones it works as a tilt meter using the motion sensors.
No ads, no tracking, no data collected.
For quick everyday checks rather than calibrated precision work.
