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.

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.

Yet another app that requires a subscription

Cannot test basic functionality without setting up a subscription. Sorry but will not subscribe to an app. Would be happy to pay a reasonable one-off payment if I had been able to test first. Potential customer lost.
