Sweet! Very nice - best free scope I’ve seen! – Sonic Tools SVM Review

[I’m checking in 8 months after I posted my original review. I wish I could give this app more than 5 stars, simply because it’s a) a free app that b) does what it says it will do, c) still has non-annoying advertising, and d) I’m still using it almost a year later. Not many apps can measure up to that standard. I saw another review that complained about accuracy, and based on personal experience I can say that Sonic Tools is surprisingly accurate: I didn’t do comprehensive testing, but I used it for some audio in the 70-130Hz range and it was spot-on] This is a very nice free app! I’m sure there are much more expensive scope apps with more bells and whistles, but if you want a quick read on waveform, frequency, spectrum, amplitude - this app has got you covered. Yeah, there’s a banner ad - it’s not especially obtrusive. I can’t claim to have given the vibration or magnetic field options much of a workout, but the plain audio stuff seems reasonably accurate. In short: check this one out before you go spending money on something else.
