Works, I guess. Best summed up with a "Meh". Definitely not worth $5, stick with the free version.
Does not save settings, ie at every restart you need to adjust settings again. Settings buttons are white on white, at least with a dark theme. I rather stick to the free version.
It's very good
Upgraded but still getting basic version,to get pro I have to go on play store and open it from that.
I downloaded and installed the free version to help determine how microphones were performing as a project that came out of difficulty communicating with others who had hearing disabilities. The free version is limited to no options other than the default, but stated that the pro version had the ability to adjust the amplitude range, so, I paid for and installed this pro version only to find that if there is an amplitude adjustment, it makes no difference in the display. It appears that the amplitude adjustment is set by sliding the left column (there is no apparent help file) but doing so made no apparent difference on the display when testing. In addition, the website listed here and in the payment receipt is dead. It's a potentially valuable tool, but there is no way to tell.
I'd give it 5 stars if I could use an external audio input.
Useful application, I have hypersensitivity to sound (as a result of sensory dysregulation due to Autism) which means I can hear above, and below human ranges. and I use this app to find certian sounds that bother me. Worth every $$$
Perfect app for a quick look. It is very easy to use and very intuitive.
I would give it 5 stars and pay twice as much if it had a crosshair to see exactly which frequency is peaking. Like spectrogram pro for ios has.
need to let us choose freq range.
