HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (50 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Leider keine Auswahl des Mikros möglich

Die App ist schön, aber leider kann man nicht auswählen welches Mikro für die Messung genutzt wird, daher leider 2 Sterne Abzug.

★★★★★Apr 7, 2023
Viel Lärm um nichts

Werbung kommt nicht nur als Banner, was kein Problem wäre. Aber zusätzlich im 15sek. Takt popt eine Webevideo auf. Das ist mir deutlich zuviel und das für so eine recht simple gestrickte App, bei der es einige andere gibt. Und gleich gelöscht.

★★★★★Jun 27, 2022
Leider ungenau

Die App ist an sich nicht schlecht. Aber sie ist zu leise eingestellt. Das heißt es fehlen immer ein paar Dezibel. Normale Gesprächslautstärke liegt bei etwa 65dB und die App zeigt lediglich 54dB an. Das ist zu wenig.

★★★★★Oct 3, 2021
Inaccurate and unusable

Very inaccurate (+-20db) and ADS on startup. Unusable

★★★★★Aug 1, 2021
Fluglärm

Der Schallpegelmesser ist sehr sensibel. Leider sitze ich mit Hunden unter der Einflugschneise und messe den Lärm! Dabei ist die App einfach gigantisch. Politiker und zuständige Behörden sollten diese App nutzen um sich klar zu werden das sie die Verantwortung für Lärmbelästigung tragen.

★★★★★Jul 31, 2021
Super App. Und kostenlos.

Danke
