Our app has the possibility to synchronize with the Health app. To do this, you need to go to the app settings and turn on the health tab there. After that, information about the volume of the ambient noise will be transmitted to the Health app, so you can track the amount of consumed noise. You can also set the interval of data on the incoming noise.

The app uses a microphone to track the sound pressure level. You can record information about the ambient noise in real time, as well as save all data in a playlist so that you can return to this data at any time.

Do you work in high noise environments? Do you want to find out if the neighbors are not exceeding the permissible volume values? Or maybe you want to monitor the health of your ears? If yes, our app can serve you as a faithful assistant.
