How does it work?

  • -The app tracks the user’s location in real-time.
  • -Once the user enters a checkpoint’s active area, the corresponding audio file starts playing and stops once the user leaves the radius.
  • -Users can tap on checkpoints to display a callout with a brief description of the story and listen to the audio file if desired.
