About this app
If you place the corner of your phone against an object, the angle of inclination on the round protractor is immediately visible. If you place it against two surfaces in succession, it measures the angle between the two surfaces.
✔ Digital Protractor (Home Screen)
＊ Stand the phone upright and place a corner against it to display a horizontal reference range of 0 to 360°; lay it flat to display the angle of inclination plus a downward arrow.
＊ Use [Reference 0] to align the current face to 0° and measure the relative angle.
＊ [Angle Between Two Faces]: When placed against the first face → second face, the angle formed by the two faces · interior angle.
＊ [Target Angle Notification]: Sound or vibration when the angle matches 30 · 45 · 60 · 90° or a custom angle.
＊ Complementary angle · Complementary angle, Units ° · % · Radians, Fixed value.
✔ Measurement Modes
＊ Measure Angle with Photo: Align three points on a photo you took or selected (New Feature).
＊ On-Screen Protractor: Place a small object on the screen and align three points (New Feature).
＊ AR Angle Measurement: Measure angles by placing points in space with the camera (New Feature).
＊ Tilt Measurement: Lean the phone against a surface to display the angle of inclination · slope · inclination (New Feature).
＊ Basic Protractor: Two lines like a real protractor. Scale, angle between two arms, 3-step size
* Camera protractor · Three-point free protractor
* Automotive inclinometer: Vehicle front/rear · left/right inclination
* Laser level · Laser grid level: Horizontal line above the camera screen
✔ Recommended for:
* Those who need to align angles in woodworking, interior design, or DIY
* Those curious about the slope of ramps, roofs, or stairs
* Those leveling picture frames or shelves, or leveling vehicles for camping or car camping
* Students who need to measure angles for math or science homework
※ Uses the phone's accelerometer (tilt) sensor. To measure accurately, please remove the phone case and read the [Essential Guide Before Use] once.
