Smartphones can perform dozens of tasks that you’d never expect from a phone, and luckily, Android offers a variety of different free measurement apps.
If you’ve ever found yourself wanting to measure something but don’t have a ruler or tape measure on hand, measuring apps on your phone can come to the rescue. They range from the fairly simple to highly advanced options that make use of augmented reality to give pretty accurate readings. While the iPhone and some Android phones have built-in measuring features, they are often quite basic, which can necessitate dedicated apps with more features. Luckily, there are some great free measurement apps available on Android that can do everything from replicating the iPhone’s height-measurement trick to calculating the perimeter of a room, checking for inclines, and more.
These apps make clever use of your phone’s camera and sensors to provide surprisingly accurate results. So the next time you want to check if a piece of furniture will fit in your living room, don’t bother asking around for a tape measure. You can simply download one of these free apps and get the readings you need in seconds.
The Ruler app by NixGame is extremely simple to use, and therein lies its brilliance. It converts your phone into a ruler, which proves very convenient when you need to quickly measure something small. It’s best suited to measuring objects that are not bigger than your screen and it is super easy to use. It’s backed by over 10 million downloads and a strong average rating of 4.5/5 on the Play Store. Many users highlight its reliability once properly calibrated. That is, by comparing it against a coin, a standard ruler, or another known object, the app can deliver surprisingly accurate results, even for detailed craft or hobby work.
Despite it’s simplicity, it’s got handy features like support for both metric and imperial units, a unit converter (millimeters to inches, centimeters to inches), and a built-in protractor to measure angles. However, the free version does include ads, which can be distracting. To get rid of ads and enjoy more features, you’ll need to purchase Ruler Pro for $2.
