ON Diameter

Discover ON Diameter, a highly practical application for measuring the diameter and area of circular objects right on your smartphone's screen. It is suitable for a variety of items, such as CDs, coins, tables, and container lids, capable of accurately gauging circles much larger than your device’s screen, making it a perfect solution for items up to 15 times longer than the length of your screen.

The convenience of this tool lies in its user-friendly interface. Simply position the object on your screen and adjust the three cross points to align with the object's boundaries. The measurements for diameter and area appear automatically, enhancing the ease of use. Adaptability is also a key advantage, as switching between millimeters and inches is seamless with just a tap.

Initial calibration is quick and required only once upon installation, ensuring precision. This innovative tool eliminates the challenges of measuring large diameters with conventional tools, such as rulers or measuring tapes, that require finding the center or precise opposite arc points.

Among the top features geared toward providing an optimal user experience are measurement unit choices, screen lock/unlock functions, instant reset, and automatic alignment of measurement results. Area calculation, a 5X Scroll Ball, grid line displays, and customization options for theme and text color and size further tailor the app to users' needs. The smart design also includes keeping the screen awake for uninterrupted work.

For guidance on usage, the built-in User Guide will assist you. The application aims to simplify and expedite the process of measuring diameters for users, inviting exploration of its capabilities which stand as practical as carrying a large caliper or measuring tape in your device. ON Diameter is available for free, ready to enhance efficiency and accuracy for various measuring tasks.
