Ruler 2: As Good As An iPhone Ruler Can Get

For a device with a 3-inch screen, the iPhone has a pretty impressive resume: phone, map, camera, sketchbook, dedicated Doodle Jump playing machine. And for $1.19, the newly revamped Ruler 2 app makes it a pretty decent measuring thinger too.

Ruler 2, an overhauled version of an apparently less-good Ruler 1, offers a simple, functional ruler that you can drag to measure things smaller than the size of your screen. Measuring things that are longer than your iPhone, as you'd imagine, isn't quite as precise: you swipe the ruler to extend it a length and then physically move your iPhone, keeping track of where the left side of the screen should be with your finger. It sounds kind of confusing, but a nice how to video that plays when you first launch the app brings you up to speed quickly.

Measurements can be labelled and saved to a folder so you don't have to mark them down elsewhere, and overall, the app has a nice, straightforward design. If you think you'll ever need to measure something small with accuracy, or measure something slightly less small with slightly less accuracy, Ruler 2's worth your $1.19. [iTunes]
