Ruler is an Android application developed by Apptist that allows users to measure length using their smartphones. This utility and tools app offers a simple and efficient way to measure the length of various objects.

With Ruler, users can easily measure objects that are longer than their smartphone by utilizing the scroll mode. This feature allows users to place the object next to the phone, support it with their thumb and middle finger, and gradually move the phone to measure the length.

To measure length, users can choose between fixed gradation and scroll gradation. In the fixed gradation mode, users place the object on the smartphone, place their finger on the screen, and move towards the edge of the object. In the scroll gradation mode, users follow the aforementioned process for objects longer than the smartphone.

Ruler also offers additional features such as measurement length saving, support for both centimeters and inches units, and the ability to set tiny gradations. This ensures precise and accurate measurements for users in a variety of situations.

Make length measurement a breeze with Ruler, the convenient and user-friendly app for your Android device.
