Difficult to Use

Oscilloscope is exactly what it says it is, an oscilloscope for the iPhone. Just like a real oscilloscope, however, its a little difficult to use.
For instance, in trigger mode, you have to drag directly on the trigger to move the level, instead of on the trigger line. If you drag elsewhere, youre kicked out of that mode. That was really confusing and took me more than a couple tries to figure out.

The "F-GENERATOR", as its called in the app, but "Signal Generator" here in the website, is pretty kludgy to use as well. Its simple enough to get some signal being played out, but adjusting the frequency is difficult with the small buttons they provide. I dont see any reason to use non-standard UI here. It is quite nice, however, that you can have two-channel output for the signal generator.

Also, the maximum time/division is 10 milliseconds, showing no more than 100 milliseconds at a time. Thats tiny! Theres plenty of other oscilloscopes on the app store that show much more. It feels really limiting.

Its clear that the authors tried to emulate the style of a stand-alone oscilloscope, but the controls just dont feel right on the iPhone. The difficult UI, combined with the scale limitations, dont make this a good value at $15. It does have a fast display, but that doesnt matter much if I cant use it.
