Ruler: Tape Measure & Level

Turn your iPhone into a complete measuring kit. AR Ruler uses the camera and Apple's ARKit to measure real objects and spaces, and adds five sensor tools that work without AR. MEASURE WITH THE CAMERA • Distance — tap two points, get the exact length • Multi-line & perimeter — chain as many points as you need • Height — measure a person or object from the floor up • Area — outline any surface and read its size • Volume — box out an object and get its cubic size • Angle — measure corners and slopes in degrees TOOLS THAT WORK ANYWHERE • On-screen ruler — real-size, in centimetres or inches, with credit-card calibration for perfect accuracy on any device • Bubble level — two-axis, with a calibration offset so your case doesn't throw it off • Protractor — read any tilt or slope, with a freeze button for awkward spots • Compass — true north heading • Unit converter — length, area and volume, fully offline BUILT FOR ACCURACY Every measurement shows a confidence indicator. When the light is low, the surface has no texture, you're moving too fast, or the target is too far away, the app tells you — and tells you what to do about it. Most measuring apps quietly hand you a wrong number instead. On iPhones with LiDAR, depth data is used automatically for even better precision. METRIC AND IMPERIAL Switch instantly between millimetres, centimetres and metres, or feet and fractional inches down to sixteenths. NO ACCOUNT, NO TRACKING No sign-up, no analytics, no data collection. Measurements stay on your device. AR features require an ARKit-compatible iPhone. The screen ruler, level, protractor, compass and converter work on any supported device. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
