Sure, you can take awesome selfies and delight the entire Internet, but there’s some pretty amazing technology that the tiny computer and advanced camera in your pocket can do.

Do the math.

In the app called PhotoMath, a frame appears on your phone’s screen, and you position the camera so the problem is inside the frame. Take a picture, and the app solves it for you, and then gives you a breakdown of the steps, so at least you can learn how it’s done.

Get the typeface.

There are so many cool typefaces and fonts out there. (For example: The one Wes Anderson uses on all his movies? Futura. The credits MTV uses on music videos? Kabel Black.) With an app called WhatTheFont, you can find out instantly what a font is. Take a photo of some words and the app will give you several possibilities.

Find that color.

Scan a camera over your surroundings, select an area, and the program Color Identifier will tell you exactly what color it correlates to in the ColorHex database of thousands of colors.

Check the mole.

Freaked out by a mole or weird spot, but not sure if you should ask a doctor to look at it? SkinVision allows you to use your cell phone camera to focus in on a skin abnormality, and then it analyzes it.

Measure it.

No more tape measures or rulers and making sure you’re holding them completely straight. An app called EasyMeasure uses your camera’s relative position and tilt angle to figure out distances and measurements. You can find out how far away an object is, when trying to determine if a piece of furniture will fit, for example, or even the height of a building.
