There are apps for everything – from writing on virtual walls to measuring distances with your phone’s microphone. Today, we document three of these apps that you didn’t even believe existed.

Type n Walk

Today, texting is one of the most used features of smartphones – but it isn’t perfect. Type n Walk is an app that helps you easily maneuver around obstacles while texting, such as people and trees, by displaying a transparent view of what’s directly in front of you!

WallitApp

Imagine yourself as a graffiti artist and the world is your canvas – there’s an app for that. The Wallit app allows you to graffiti hundreds of secret digital walls throughout the world. But instead of using spray paint, you can leave your mark by posting a message, photo or video on designated walls. There are walls in San Francisco, New York, Tokyo, Istanbul, Panama and in other popular cities. You can only post, or see what other people have posted, when you’re at the wall’s physical location. Rumor has it that there is a marriage proposal on the Golden Gate bridge…

Sonar Ruler

Drop the tape measure, you won’t need it next time you measure dimensions. Sonar Ruler uses your phone’s microphone to send a short pulse from the speaker and measures how long that pulse takes to bounce back – gauging your distance from objects.
