Volume Booster

Volume Booster is an app that lets you adjust the volume of specific sounds on your smartphone. This means that you can adjust the volume of calls, the alarm, and notifications, independently of one another. Thanks to this, you can make the volume of a call really low, but keep the volume of notifications or alarms high.

Besides customizing the volume settings, with Volume Booster you can change to vibration mode with just a touch. You can also create different sound profiles depending on whether you are using headphones or not.

Volume Booster is an app that, although it doesn't let you turn your device's volume up beyond technical possibilities, it does let you customize your sound settings.
