SignalScope turns your iPhone into a powerful real-time spectrum analyzer and oscilloscope. You can "touch" your signals with highly interactive, multi-touch-enabled analyzer displays.
Getting started is as simple as tapping the SignalScope icon in the Home Screen and tapping the Start button in the toolbar once SignalScope opens.
SignalScope lets you analyze audio, from the built-in or headset microphone, or acceleration, from the built-in, three-axis accelerometer.
