HearUsHere is an app that combines multiple audio tours. By opening the app the closest audio tour in your location will show up first. The audio tours are specially created for their locations, they consist stories and music. GPS triggers the audio file that matches your location.
The tours provide a new way of experiencing an audio tour. Listening to the volume of the audio files gives you a sense of where you are and where to go.
Continued use of GPS running in the background can dramatically decrease battery life.
