Diskometer is a handy app  for dimension measurements. You can measure length, width, size, ratio, angle, area, arc length of objects. You can use camera in the app to take a picture or upload picture form the gallery to do measurements on it. You would need a circular reference with known size to preform measurements. App can be used as a ruler or tape measure.

Most common reference objects like DVD/CD, coins, etc. are included in the application. Moreover you can use your own custom circular objects with known size to perform measurements.

Modes:

- FreeHand-Mode - measure an object in any direction.
