Carl Reinke has as one person put it, gifted the world with his totally free application. Once you figure out how to set it up. It shows the river of sound that surrounds us. There's absolutely zero advertisements. It works online as well as offline. You don't even have to have any internet whatsoever. I will say that it is better to use multiple phones. Because some have better microphones than others. I would tell everyone that uses this to try using all of the phones that you own. Best app.

Stop looking through apps, this is the one youre looking for. Period. Great specrum viewer app, I use it on many devices. Works flawlessly on all but the oldest of them(were talking android 2 era devices, so it has a pass). I've been using it for years and I still find neat ways of utilizing it. About the only thing it lacks is a record function, but you can always record the screen or screen cap.

This app is wonderful! I am building tuned struck musical instruments. If you crank up the sample rate & interval, and set the decimation appropriately, it provides the resolution required to tune musical instruments. It is the only spectrum analyzer app I have found so far that can do so. Thank you, thank you, THANK YOU! You have obviated my need to build a real-time pitch extractor app based on the "poor man's autocorrelator" algorithm.
