Volume by Velocity

"Hands down best way to listen to podcasts and audio books in the car." - johnM
“...it’s the best one out there by far." - Graham

Volumatic™ is the best app to control your music volume based on your speed. As you accelerate, an algorithm increases your volume to counteract your cars road noise.

The simple Automatic mode, uses special settings designed to optimally block road noise as well as keep you from disturbing others at lights. For those who want full control, the manual mode allows you to set the speed and volume range to best fit your taste.

* When Volumatic changes your device volume, iOS presents a volume changing indicator (the same one that appears when using the side buttons). This can sometimes get in the way while using other apps.

** Volumatic uses you GPS to determine your current speed. Continued use of GPS running in the background can dramatically decrease battery life. To keep your device charged we recommend plugging it in while using the Volumatic app. Show More
