RulerPhone measures anything your iPhone can take a picture of.
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, driver's license, or credit card.
New Version! RulerPhone can now also measure the distance from your iPhone's camera to any object and save any measurements to your photo library!
Note: RulerPhone Lite allows measurements up to 1.5 feet. To accurately measure anything from a few inches to beyond 12 feet, buy the full version of RulerPhone.
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 you'd like to measure, snap a picture with your iPhone's 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 you're measuring using the card in your picture as reference. Once you've 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 RulerPhone's accuracy depends on the user's ability to follow the on-screen instructions and tips for accuracy. Once these steps are mastered, RulerPhone is a very accurate tool. RulerPhone's accuracy will also continue to increase as the iPhone's 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 object's height and/or width. Similarly, if you take a picture with your MetroCard or driver's license off at an angle instead of pointing directly at the camera, RulerPhone's accuracy will be compromised. All of this information is in RulerPhone's instructions and accuracy tips that are available once you buy the app, and more information is found at the website below.

Reviews
Worked perfectly!
Scot Perry
After properly aligning the credit card so that it was perfectly parallel with the camera and in the center of the frame, and after making sure that the lighting was good enough, got it to work wonderfully. Went ahead and bought the paid app without any regrets. Thanks for a wonderful app!
Worth buying the full version
Kamholio
I see this as a technology demo. It measures things up to 1.5 feet, so you can compare the results with a tape measure. I followed the on screen directions and found it easy to use and accurate. I immediately bought the full version and could not be happier with the app.
Really bad app
BuffaloRhino
This is a neat toy, but as a measuring tool it fails badly. My job requires me to use a tape measure often, so if I can carry another tool on my phone all the better. I gave this tool the litmus test, measuring known distances and widths, heights. So far the app is 0 for 10. Save your money and get the tape.
Needs an update

The app crashes every time you try to take a picture to measure. Do not buy. Waste of time.
Lies!
PetetNels107
This app is a lie, and a scam! It calls itself free, but as soon as you load it up it will ask for a $4 payment to do anything! Then, it will crash whenever you take pictures with it, you'll never even see a measurement screen like in the pictures from the app store! This app is just set up to lure you just far enough to give them your money without doing anything for you!
