Proximity is a friend discovery application that notifies users when selected friends are nearby. It allows users to specify a distance range and will send push notifications to connected friends within that radius. User testing found that friend selection and distance settings were the most important and satisfying features. The app is ready for initial release on the Google Play store, and next steps include continued UI improvements and developing iOS compatibility.
