Oscilloscope App Reviews

Tut was es soll.

...without requiring external hardware - any audio interface will do. Easy to use.

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.

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.

Best on the app store for sure!

Does not work on first gen iPhone, crashes on launch.

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 OScope.

These guys are great. I asked for the audio out so you can study filter circuits and got a dual signal generator! Left and right separately programmable, frequency and wave shape. Great display. This app rocks.

Oscilloscope works right out of the box using the built-in mike for input. For more serious work the USB audio interface via the iPad Camera connection kit is recommended, though I have not tried that yet. The built-in signal (function) generator is useful as you can get audio feedback while viewing the wave shapes. All the controls and adjustments normally found on a scope are nicely integrated into the iPad / Pod / Phone environment. This app certainly costs way less than a comparable o-scope! -Rob-

This may sound funny but I bought this on a whim. I was an engineering technician back in the late 80s and remember the old Tektronix oscilloscopes. Imagine being able to simplify all those knobs , switches buttons into a simplified touch interface. Oscilloscope shows just how that can be done. Simple to use UI, great graphics.

Im an Electrical Engineer and have found both Onyx Oscilloscope and Analyzer very useful in the lab. Im using these apps with the Alesis IO Dock, a couple XLR to BNC adapters and probes. Highly recommended. Im looking forward to further mathematical analysis options and data recording options.

As a professional engineer and audiophile I find this app the easiest to use and most useful by far. No comparison. Great job!

I like the flexibility of changing the time base and voltage scale so easily. Could use a bit more info on using the variable frequency signal generator. Very good job on everything else!

Reliable app with all the basic features. If it had a way to capture the data and email it as a CSV file with XY then it would be incredible.

I you added Audiobus support it would be perfect.

I got this app to work with ultrasonic transducers but I found out once I started working with it that the shortest time step you can have is 0.5 ms. So at 20 kHz you have 10 peaks per square and is pretty useless beyond that point. Im working with 450 kHz and the display is just a yellow blur. Id give this app five stars if it worked for the frequencies I needed (which most oscilloscopes would) but since it was a waste of money for my needs I give it two stars.

The 22KHz limit is a huge negative. All my waveforms end up looking like square waves. Increase the limit and the functionality would really improve. (Im mad at myself since I didnt notice the limit before purchasing. Dont be like me, read the description carefully)

This is a great App for low frequency work! I am porting a special low pass filter stereo music signal using the recommended input devices for an XY music display, and using Airplay to send to my TV. All the App features work great and this is a really fun App for the oscilloscope aficionados out there like me.

Nice job with this app! I would like to see a few more features but honestly it does way more than I expected! I would like to see integration with Audiobus or Inter-App Audio. The cursor icons could be a bit bigger on the iPhone. The large beefy border of my Pelican case make it more difficult to grab the cursor handles. Nice work!
