Highly functional and useful tool..!

I am impressed by how useful this app is, if your needs are simply for basic audio frequency waveform display, this may be all the scope you need.

I did have a few crashes and the “Support” link on this page has no contact information for the company. I’d like to be able to inform them about the minor issues I’ve encountered.

Really great app!

I needed a way to display waveforms generated by synthesizers for a class I’m teaching. This app saves me the trouble of hauling my aging Oscilloscope to class each week. It accurately displays waveforms, it’s responsive, and it works great with signals input from my audio interface.

Easy to use

It just took me a few minutes to figure out what I had to do. Nice!
