## What is iAngle?

Turn your iPhone Duo into a protractor. Open the fold and iAngle shows the hinge angle live in degrees, with a 0.1° readout. Close it, and the outer display becomes a tilt meter.

OPEN: A PROTRACTOR IN YOUR HANDS
iPhone Duo reports the angle of its hinge, and iAngle turns it into a big, clear reading. Set the two halves to 90°, 120° or any angle you need, or measure something by fitting the phone around it. The reading and the controls sit on either side of the fold, so nothing gets in the way of the hinge.

CLOSED: TILT METER AND ANGLE FINDER
Folded shut, iAngle uses the motion sensors instead. Lay an edge against a shelf, a ramp, a roof or a picture frame and read the slope on the outer display. 0° is flat, 90° is upright.

BUILT FOR REAL USE
• Hold – freeze the reading so you can look at it after you move the phone
• Zero – measure relative to the current angle, for comparing two angles
• Outer/Inner – flip to 180° minus the angle in one tap
• Haptic tick every 5°, so you can feel the angle without looking
• Large, high-contrast numbers and protractor dial
• Light and dark mode, VoiceOver support

PRIVATE BY DESIGN
Free to download: the protractor and tilt meter are free, and Hold, Zero and Outer/Inner are a one-time unlock. No ads, no subscription, no account, no tracking. iAngle collects no data at all.

iAngle requires iPhone Duo. Readings depend on your device's sensors and are meant for everyday use, not as a certified measuring instrument.
