Swift Volume is a multimedia application developed by Kris Harris for iPhone users. This free app is designed for athletes and speed enthusiasts who want to listen to music while on the move and still be aware of their surroundings.

With Swift Volume, users can easily adjust their volume settings based on their speed. The app allows you to set your desired low speed volume, high speed volume, and the speed at which the volume changes. This way, you can ensure that your music remains at an appropriate level whether you're cruising or stationary.

It's worth noting that Swift Volume does not store or collect any location information. The app only utilizes your device's Location Services to determine your speed. However, it's important to be aware that using Location Services can have an impact on your device's battery life.

When Swift Volume is running in the background and a volume change is triggered, a HUD volume display appears on the screen as required by iOS. It's important to mention that this app is primarily intended for outdoor use, as it relies on GPS to accurately determine velocity, and GPS functionality may not work effectively indoors.

Overall, Swift Volume is a handy tool for individuals who want to have control over their music volume while on the move. Its simple and intuitive interface, along with its focus on user safety, make it a valuable addition to any athlete or speed enthusiast's arsenal.
