This is the only working microphone app for Android that you are able to find on the Google Store till date. It is the only app that works in real time, but as far as sound goes, well, it is awful. There is no way to compare this with a real microphone, and that's mainly because of the fact that Android phones and tablets do not have really good microphones. The app is not bad and provides even themes and an equalisizer, which you cannot really hear if you have a bad microphone. But if you do, you can set the app to be stereo, you can set the equalisizer measurement unit, the visibility of quick settings, a volume adjuster and many more settings. I tested this microphone with my Fender 10g amp and it did work but with great echo and reverb even if I went far from the speaker. The only thing this microphone would be good for would be listening to the people from another place from where you have 5 ft. of cable to your headset. For music purposes thought, this app is not good at all because it cannot be used with external microphones if your phone does not have a multi-purpose input and in the end the app does not work with large amplifiers.
