Description
"I use this for analog, and audio measurements. Attach an Apple USB adapter and a $40 stereo A-D converter available online, and my iPad is like a $300 O'Scope." -thymeout-
Oscilloscope app is great for analyzing audio range signals, or learning oscilloscope measurement basics. The interface includes many standard oscilloscope controls, such as: triggering, time and voltage per division, signal measurement cursors, and more.
The app incorporates a signal (function) generator capable of generating sine, square, triangle, and sawtooth waveforms of up to 22 KHz. Calibration to an external reference signal is supported, guaranteeing the accuracy of measurements.
Input can be acquired via the built-in microphone or an external mic/probe connected to the headset connector. For best results, use an external audio interface connected to your device dock. This allows for standard audio equipment to be connected, as well as for dual channel input. Oscilloscope probes also be connected (using a BNC connector). When feeding external signals via probes, you should take care not to exceed 1V AC voltage. Currently iDevices support only AC input.

Ratings and Reviews
Almost perfect for tuning the “beat” of a pendulum clock
I am using this app to tune the “beat” of pendulum clocks. When the time from tick to tock is the same as time from tock to tick then the clock is in beat and will run reliably assuming no other problems.
Why is this app “almost perfect” ? Because the maximum buffer size is 2 seconds which is not long enough for grandfather clocks. All else on app is great.
To improve the app:
1) increase maximum buffer size to 10 seconds. Perhaps larger for some other uses. The iPad has lots of memory so this should be an easy improvement.
2) add feature to allow saving screen as an image. Many users would like this feature.

Please check out the ClockMaster app - specifically designed for pendulum clocks ;)

Pricey for what you get
Neat, but pricey for what you get. It would be nice if the app had a spectrum analyzer mode. Also, can you put the x & y scales on the tick marks? What about log scales? It would be beneficial if a help file existed describing how to modify a plugin microphone to accept other signals, I.e. voltage, current. This app has potential.
