Turns your iPhone into a carpenter's bubble level, inch ruler, and centimeter ruler.

Uses the accelerometer in your iPhone or iPod Touch to display an animated bubble level. A numeric readout displays the tilt in degrees. Sound feedback lets you know when the device is level.

This application is based on sample code given to iPhone developers, with the addition of rulers. I take absolutely no credit for creating this application. I just think it's cool enough that it should be distributed for free.

The code license states that developers may "modify and redistribute the Apple Software, with or without modifications, in source and/or binary forms". I'm distributing it modified for the world to enjoy.

Thank you Apple for creating this incredible iPhone platform!
