Good o-scope for the price

The software and hardware are very nice. The hardware amounts to a 5 MHz analog probe, and 4 digital probes. This is nice, but I would like to see a 2x analog probe hardware accessory, even if it is at the cost of speed. Be sure to pay attention to the probe specs and don't exceed the max voltages.

The software is very modern, the UI is straight forward and mostly self-explanatory. All the expected data logging features were there.

I found that pinch to zoom in and out to be clunky. a smooth zoom option would be nice.

We just released a 2x analog probe version! Check out: iMSO-204x. Hope with that improvement, we can win over a five star review (from the four star provided). Thank you for taking the time to provide feedback. It matters! And we're listening!

Very useful portable tool

I have a university lab full of high end, high speed test gear like 25 GHz 'scopes and the like. But I also do some home projects for a variety of reasons and help out a local commercial diesel repair shop when they have weird electronics problems. While I have a low end 'scope at home, I find the portability of the OSCIUM device a great asset for many of my tasks where I do not need high bandwidth. A recent example was finding CAM bus problems on the big diesel rig. The iPad was easy to handle in tight spaces and the OSCIM scope did its job and we nailed the problem quickly (saw bad reflections and isolated a poor connector).

While I would like to see a similar product from OSCIUM with a dual channel analog 'scope, this tool has been most useful and for my use rate it as a 5 star.

Thank you for the love! Did you know that we recently released a dual channel analog version? Check out: iMSO-204x. It's exactly what you have requested :)

Update: using this app with AirPlay mirroring to my apple tv totally works, I still like using the HDMI adapter since there's no latency that way, but I'm still in love with this scope, thanks again Oscium.

I've had this scope for a while now and it's still working great. If you feel that the iPhones screen is too small to do anything serious know that it supports using the apple HDMI out adapter, and it is pretty sweet. Note that I had to cut a tiny bit of superfluous plastic off the side of my HDMI cable, but I'm pretty sure anybody who buys a scope is ok with a slight cable mod.
I've been using this in lieu of a logic probe lately and I'm very pleased with its abilities, thank you oscium.

AirPlay is a fantastic little feature, isn't it! Also works with Apple TV (for us with a projector, like in a classroom). Thanks for taking the time to review the scope. We appreciate the love and the title. Awesome is where our company name came from: awesome + oscilloscope = Oscium. :)
