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.


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

I have worked in the Metrology business for the past 25 years. Now I can make small measurements on my phone with a metal scale lying next to the part for calibration. With a 4x zoom on my camera I can measure down to .005". I took a snapshot through a 5x microscope objective and can resolve imaging down to .001". For fun I was able to push the line circles together to show 2 microns length. Maybe they can link a key to make steps. Great app.

Dear Robert, Thank you very much for sharing your experience with our app! We appreciate your support here and also in-depth accuracy testing and showing possible use cases on our Facebook. We understand you suggest to add keys to move circles in small steps for better adjustment. We will consider your request in future updates. VIsTech.Projects
