iPhone Applications That Replace Your Tools

The Wired Blog has an interesting list of applications that emulate and replace actual hardware tools -




A Level, which uses the iPhone's tilt-sensors to emulate a spirit level, complete with a virtual bobbing bubble in a tube. Its latest version now includes calibration. It is surprisingly accurate.




TapeMeasure, as its name implies, is used for length/distance measurements. However it use the 3G's GPS to do so and hence can't be that precise.




Speed Alert replaces your car's speedometer with a far less accurate, GPS-based speedometer. A useful feature though is the alarm when you exceed a pre-set speed limit.




Caliper intended for close-up work measurement and is simple to use but is limited to the length of the iPhone's screen.
