Angle Gauge

Angle Gauge turns the hinge of iPhone Duo into a precision protractor. Set the phone into a corner, against two surfaces or across a joint, and read the angle to a tenth of a degree. MEASURE • Live angle to 0.1°, on the inside display or the outside one • Hold, Auto-Hold when the reading settles, and Zero Here for relative angles • Supplement, bisect and miter angle for every reading • Snap to 1°, 5°, 15° or your own step TARGET • Pick 45°, 90° or any angle with presets and a fine stepper • Haptics build as you get close, then click when you arrive • Tolerance from ±2° down to ±0.25° MATCH • Capture angles into a named library • Find them again later, by feel LEVEL • Bubble level when the phone lies flat, line level on its edge • Two-step calibration cancels the camera bump and the slope of your table • On iPhone Duo, read the hinge relative to true level ON EVERY IPHONE The level works…
