About ON Diameter
ON DIAMETER is the best diameter measuring tool on android. This measuring tool will help you to measures the diameter and area of any circular objects on the device's screen.
This advance measuring tool let you measures objects that much larger than device screen size. From some experiment we have done so far, it can accurately measures the diameter of any circular objects up to 15 times longer than the screen length. For example, you can use it to measures the diameter of a compact disc, coins, round table, biscuits, masking tape, container cover, etc.
ON Diameter is so incredibly convenient and easy to use. You just need to place the measured object anywhere on the screen and move the 3 cross points to align with the object boundary. The object diameter and area will show on the screen automatically, as shown in the preview images. You can also switch the measurement unit between millimeter and inch by just a click.
For perfect accuracy, you will be requested to do calibration at the first time you open the application. Calibration need to be carried out only one time per installation.
As we know, measure the diameter of large circular objects using ruler or measuring tape is a difficult task because we need to know the center point of the object or the two correct opposite points on the arc. This measuring tool can even measures the diameter of the object that larger than the total length of a measuring tape.
ON Diameter is the only android measuring tool application used to measures diameter. With ON Diameter, now you always bring a large caliper and measuring tape with you as in your smart phone.

The accuracy of this app utterly depends on entering the correct value of your screen size during calibration. However, the phone's reported specs may not be precise. Eg, my Galaxy J7 has a 5.5" screen, but was correctly calibrated only with a value of 5.45". The app thoughtfully provides a small ruler for "verification" in the calibration screen, which you should check with a vernier calliper and adjust the screen size value accordingly to obtain correct readings.
