    [NEW] ON DIAMETER - The only diameter measuring tool on android!!-poster_small.jpg

    ON DIAMETER is the only and the best diameter measuring tool on android. It help you measure the diameter and area of any circular objects on the device's screen.

    This advance tool let you measure objects that much larger than device screen size. From some experiment we have done so far, it can accurately measure diameter of any circular objects up to 15 times longer than the screen length. For example, you can use it to measure diameter of a compact disc, coins, round table, biscuits, masking tape, container cover, etc.

    It 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 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. With ON Diameter, now you always bring an extra large caliper with you as in your smart phone.

    ★ Inch and millimeter supported
    ★ Lock/Unlock screen
    ★ Instant reset
    ★ Easy calibration (Only one time)
    ★ Show and align measurement result automatically
    ★ Object area calculation (All modes)
    ★ 5X Scroll Ball
    ★ Show grid lines
    ★ Customizable theme, line color, line Width, text color, text size
    ★ Simple & smart user interface design
    ★ Keep screen awake

    For more details information about how to use the app, please refer User Guide in this app.

    ON Diameter is a free diameter measuring instrument on android. We hope this free app will bring convenience to you and save you time whenever you need to measure diameter.

    Hey, that actually seems like it will be useful!

    I can see some issues with trying to hold a large circular object flat against the screen (since most of it will off the phone).

    I'm a rocketry hobbyist and I often find myself struggling to accurately determine the diameter of a body tube or nose cone. Your app looks like it will be handy. I'll give it a try and mention it on my rocketry web site.
