From Spud Pickles:
Ghost Radar for iPhone employs a proprietary algorithm to analyze the quantum flux. The measurements are displayed graphically as blips on the radar along with numeric and textual readouts. Use your Ghost Radar to hunt for odd changes in the flux. Hunters of all types may find anomalous areas of their environment where readings simply can't be explained. Ghost Radar measures and analyzes small fluctuations in the gravitational field around your iPhone or iPod touch. When the radar first starts it will be very sensitive to the noise in your environment perhaps giving false readings. After several minutes of self adjustment the radar will learn how to filter out the noise. The longer the radar is allowed to run the more sensitive it becomes to anomalous readings. What those readings mean and how you interpret them is up for debate. The theory of what is happening is that intelligent energy can be made aware of their ability to influence the sensors of the iPhone and iPod touch.
