"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.

My favorite app
This to me is exactly the ideal product of an app development community and app marketplace. I love this thing. This makes any iOS device an double as an incredibly useful tool in a new, unique way. That is to say it's also the best app among the category of all oscilloscope apps I have tried. The UI is super simple, to the point of actually being beautiful. The pinching is a little hard to get used to. I would slip at first and adjust the offset when I was trying to adjust the voltage. Now I still slip a little when adjusting the time base, but it's easy enough to correct. And Auto makes it easy to not even worry about any of that. Thank you. Well worth the price.
This app could do much better with on screen controls for timebase and channel gain settings. The generator levels seem unadjustable. Extremely annoying is the scale changes do not adhere to standard scope 1,2,5 sequence so you end up with silly fullscale and time settings.
This app misses thr mark by a mile, i am chucking this.
Usable for Sound Synthesis; Needs iOS9 Slide-Over feature
Decent app to observe visual changes when adjusting knobs, but there's a privileged problem of needing more than one device to observe the waveform while adjusting the controls of a sound generator. Sure, you can switch between the app screens, but that's not ideal.
Now! Maybe the ONYX devs can incorporate the new Slide-Over functionality that iOS9 brings—this would make this software more usable on a single device.
