Seismometer is the iPhone app that can not only let you know if you’re in an earthquake (and how bad it is at your personal epicenter), but also records and displays the movement energy of just about anything.
Seismometer uses your iPhone’s built in accelerometer to measure movements in two axes, calculate the resulting energy and draw the results on a rolling scale.
Version 1.1 updates feature noise filtering, expanded frequency settings (20, 40 , 60 and 200hz), and choice of output to logarithmic or linear scale.
99¢ buys you fun for the whole family; no additional premium charged to iPhone users located on major fault lines.
