“RulerPhone will inevitably come in handy, so you might as well buy it now!”
- got apps?

RulerPhone turns your iPhone and its camera into a true measuring tape -- all you need is something already in your wallet: a gift card, MetroCard, drivers license, or credit card.

Buy RulerPhone - the widely acclaimed, "best ruler app for the iPhone" - now for only $3.99.

New Version! RulerPhone can now also measure the distance from your iPhones camera to any object and save any measurements to your photo library!

RulerPhone is not like other apps: it does not just display an image of a ruler on your iPhone, and it does not use GPS to calculate distance. RulerPhone can accurately measure distances ranging from a few inches to 10 feet and beyond.

What others are saying:

"...one of the best applications for the iPhone."
"I was surprised how well this worked...I would buy this for $10."
"Works like a charm...super easy to use."

How does it work?

Place any credit-card sized card next to the object youd like to measure, snap a picture with your iPhones camera, align your image with the card placeholder that RulerPhone displays on-screen, and you are ready to measure anything in your picture just by dragging your finger. You can also use any picture already stored in your iPhone or iPod Touch photo library.

RulerPhone figures out the dimensions youre measuring using the card in your picture as reference. Once youve aligned the card in your image with the on-screen card placeholder, you simply drag your finger across the screen to measure distance. RulerPhone will display a ruler over your picture that you can drag and adjust to fine-tune your measurements (as seen in the screenshot below).

Is it accurate?

RulerPhone is accurate within half an inch when measuring distances of three feet or less and can be accurate within a single inch when measuring distances up to 10 feet as long as the instructions are followed closely. Much of RulerPhones accuracy depends on the users ability to follow the on-screen instructions and tips for accuracy. Once these steps are mastered, RulerPhone is a very accurate tool. RulerPhones accuracy will also continue to increase as the iPhones camera is upgraded.

When does it not work?

RulerPhone does not measure depth in a photograph. When you take a picture, RulerPhone can only measure an objects height and/or width. Similarly, if you take a picture with your MetroCard or drivers license off at an angle instead of pointing directly at the camera, RulerPhones accuracy will be compromised. All of this information is in RulerPhones instructions and accuracy tips that are available once you buy the app, and more information is found at the website below.
