For those of you who like to listen to music on your iPhone while setting up or packing up there is an app that will keep you in touch with the outside world even while wearing earbuds.
Awareness is an app that operates in the background but lets you know when a sudden noise needs your attention. It might be somebody talking to you, or a PA announcement, or perhaps a warning beep from a car or forklift. The app instantaneously picks up the sound and filters over the top of your music or radio feed. You can hold a normal conversation with your earplugs in place.
Like many apps the degree of control is quite impressive. For starters, you set the level at which you wish to be interrupted and you can select additional warnings like a sound or vibrations.
Sounds like a convenient app for music listeners with a big dose of safety built in and it is FREE for a limited time.
