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.

Never have I seen such an assembly of shill ratings in all my life, this app needs to be removed just for that reason let alone it doesn't even work! What the hell is Google doing to weed out bad apps? Obviously nothing! No wonder I rarely ever download anything here, seems like the only use for apps is to supply digital ad metrics (from bots) so they can make money off advertising! It's proven that digital ads make little to no actual revenue yet we see them filling every app here!
