This app includes a beautifully designed 30cm and 11 inch ruler for free. Blue Ruler is also less than 2MB in size, so it has an incredibly small footprint, leaving more room on your phone for the other apps you want. Why should a ruler take up any more space than that? It includes a discrete yet simple and easy to use menu at the bottom of the ruler allowing you to quickly and easily switch the units of measurement and to see the illustrated instructions. Instructions are easily accessible yet kept out of the way for the best user experience. It gives a fantastic user experience. The best way to learn how to use it, is to try it out for yourself, but here are some instructions anyway: INSTRUCTIONS FOR USE 1. Firstly, align the beginning of the ruler with the object you wish to measure. 2. Hold your finger on the other end of the screen. 3. Slide the phone (so that your finger slides along the screen, moving the ruler) while maybe resting your hand on something sturdy, along the object and continue sliding the device until your finger reaches the end of the screen. 4. Take your finger off the screen, place it on the other end of the screen and repeat the steps until you reach the end of the object. NOTE: Illustrated instructions are included with the app NOTE: Although this ruler app is one of the most accurate on of the app store, this app is not to be used for precision measuring, the ruler is only for approximate measuring. The developer is not held responsible for misuse of this tool.
Requires iOS 8.0 or later. Compatible with iPhone, iPad, and iPod touch.
