It's easier to see than to explain -- to watch the video and see AccelaRuler in action, just search for "accelaruler" on YouTube.

There is a little bit of technique involved, so PLEASE watch the tutorial video and follow the instructions. There is also a video tutorial under the info button in the app itself.

Unlike other measuring applications, AccelaRuler is not just a tiny picture of an even tinier ruler. AccelaRuler measures real things in the real world using sophisticated processing and your built-in accelerometer to estimate distances. AccelaRuler can be used to measure distances ranging from a couple of inches to 15 feet or more. Measurement accuracy is up to 2% of the actual distance, and AccelaRuler will estimate any error range for you.

• Measures distances from a few inches to 15 feet or more

• Measures at any angle, including vertically

• Measurements accurate up to 2% of the actual distance

• Measures and converts between inches, feet, and meters

Note that AccelaRuler is designed to estimate distances while sliding on flat surfaces. It will not work well carried in your hand.
