Pocket Measure

Turn your phone into a practical everyday measurement toolkit.

Pocket Measure brings several useful tools together in one simple app:

- Screen ruler with centimetre and inch scales
- Calibration using a physical ruler or a standard credit card
- Movable and rotatable full-screen ruler
- Large protractor with screen and camera overlay modes
- Level using your phone's motion sensors
- Location-free magnetic compass
- Optional AR distance measurement on supported devices
- Unit converter for length, area, volume, mass, temperature and angle

Calibrate the screen ruler for your device to improve on-screen measurements. Move the ruler to any edge, rotate it between horizontal and vertical layouts, and collapse the controls when you need more measuring space.

Use the camera protractor to align the adjustable overlay with real-world objects. Camera images stay on your device and are not uploaded by Pocket Measure.

AR measurement requires a compatible device, camera permission and Google Play Services for AR. Measurement accuracy can vary with device sensors, display information, lighting, surface texture and calibration. Pocket Measure is intended for convenient everyday estimates and is not a replacement for certified professional instruments.
