iPhone 4 Gyroscope Plus iSetSquare Equals A Great Measuring Tool - Plus A Chance To Win A Copy

Whether you're a carpenter, drafter, mathematician or just a homeowner, you're likely to come across the need to measure the angle and width of objects. iSetSquare - Geometry Drawing Triangle is a new app that uses the iPhone 4's built-in gyroscope to precisely measure angular movement. There have been plenty of apps in the App Store that already do this task, right? Well, not exactly.  The advantage of using the gyroscope over the accelerometer, in this case, is higher precision and ability to measure an angular turn from any direction, including when your iPhone 4 is lying flat on its back. iSetSquare offers a number of useful tools, including a built-in scrollable straight ruler and more than a handful of different measurement units. Measure your angle in degrees, radians, percent, or slope with the ability to quickly change the unit from a single button in the main UI or under settings. The scrollable ruler is capable of measuring linear distances in either inches or centimeters, and scrolling for measurements of both positive and negative directions. The goniometer allows you to spin the protractor on its axis or lock it and spin the wheel beneath it, an easily adjustable option from a simple one button tap. Quickly reset the ruler to zero by double-tapping it, and quickly reset the goniometer to zero or otherwise reset the start angle by tapping the center. The settings panel allows you to adjust the sensitivity, reset the calibration, prevent auto-lock, and more. The only known issue is the gyro's ability to drift a little after the motion stops. The developer is working on this and plans to release an improvement to counteract the action in the first update. iSetSquare - Geometry Drawing Triangle is already available in the app for the introductory price of just $.99.
