Ratings and reviews

I have tried this app on at least 5 devices and it doesn't even do anything, just empty graphs. Sound Analyzer app is the only free app that works for speaker testing but it requires external test tones to use it. White noise is available in other apps as well as sweeps, I used 2 devices to get good results very easily and quickly. If you've tried REW, you know how long it can take, I can run a test before my computer boots up and get the same results in seconds, accurate on Moto Stylus 5G.

I wanted to know what low frequency's are omni-present in my appartement since a few days. The app exactly shows which the frequency's are involved and there soundlevel. Exactly what I wanted know, presented in useful graphics. I don't know accurate the app measurements are (because done with a mobile phone. But other than that, this app is what you need.

Could be good but Not stable yet. The display chart locks up after 5 seconds most of the time on Android on Samsung S5. If I exit the app n come back then it works again for a few seconds. The chart page forgets the scale settings every time I exit or if Iook at the settings page. It looks promising but is not useable as is on my cell.
