Be careful

Unresponsive company
They charged me for the app, and now it no longer works. They have not responded. It was not inexpensive. I cannot recommend this company at all.

Response from developer

I'm sorry you had a poor experience. We have been striving to be highly responsive to our customers for over 23 years. Is it possible that your message didn't get through? We typically respond to inquiries submitted through our website within 24-48 hours. Please try again. We will, too.

Keeps crashing….no thanks!

Keep crashing whenever sound changes are made. If you enjoy rebooting, go ahead and try this. Otherwise, move along. (And yes, I JUST updated to a version that supposedly fixed a similar sounding crash description. Clearly it was not fixed in my case)

Doesn’t work like it used to

I have used this app for years, primarily as a teaching tool with my iPhone microphone. For some reason, it is no longer working. It will either start to record, then stop. Or it won’t work at all. The Faber SLM app seems to be working fine, so I’m not sure why the oscilloscope and FFT have stopped functioning. Very disappointing especially considering the price we pay for the subscription.

Response from developer

We're sorry that you had a disappointing experience with SignalScope X. If the app stops working as you would expect, please contact us and we will response as soon as we can. When things aren't working as expected, it can sometimes be due to a change in the way an analysis tool is configured (e.g. single shote vs auto triggering), the units and sensitivity of the selected input device or channel, etc. We'd be happy to help get it sorted so you can be up and running again.
