Although appreciate the attempt to provide this type of appi could it find it useful as a spectrum analyzer as it is now. So many similar apps that all are lacking in some way it's hard to remember which ones failed at certain things, but if I deleted it, I can say it's not going to be of any help at tuning speakers. If you're looking for that, you'll have to forget using apps and a cheap Dayton mic unless you're ok with it sounding worse than if you left it alone. Sorry but I've tried them all

Easily the best I've found. It was able to determine two exact frequency spikes that my headset produced. 7 other apps failed but this one is legitimately functional and accurate as I also tested it against tones I produced.

I've used it lots, it's simple, functional, and easy to use. So for example to quickly identify and notch out some feedback at band practice. I paid the 99c to upgrade even though the free version is useful enough.
