Beacon is just that: a way to signal to those you wish to know when you have reached your destination. With Beacon you can create groups with other users and define locations anywhere in the world. When a user crosses into or out of a defined area, other users within the group will be notified of their changes.
However, unlike other applications, Beacon maintains a heavy emphasize on privacy and data protection. The application will not constantly message others about your exact location, and ensure there isn't an unecessary invasion of privacy. When you wish to prevent your exact location from being shared with both members of your group and potential hackers, Beacon will fulfill that request by only sharing the minimal level of location updates needed for the user. Beacon will not constantly share your location with everyone, but instead will simply notify when an area has been entered or exited. With Beacon, you will not only maintain the necessary information for where you are with others, but you will also do so safely and securely.
