ON 2D-CameraMeasure is a free Android application developed by PotatotreeSoft. It is a versatile tool for object length, angle, area, diameter, and dimension measuring. With this app, you can measure anything on a 2D plane using your device's camera. It is a convenient replacement for rulers and measuring tapes in situations where traditional methods are difficult to apply.

This app is especially useful for measuring large objects, such as the size of a large screen, height of a lamp post, outer dimension of a building, and more. It allows you to measure anything quickly and easily as long as there is a known dimension as reference. ON 2D-CameraMeasure performs non-contact measurement by using the device's camera and any known length or dimension as reference. You can use the predefined common objects such as credit card, CD/DVD, and A4 paper included in the application, or use your own custom object as reference.
