Wander

Wander is an application designed to connect people who cross paths multiple times during their daily routines. Every day people walk past each other, possibly many times, without ever realizing that they crossed paths. With Wander, users are able to see a list of people they have been matched with after crossing paths multiple times and can view the profiles of their matches. Matches can chat with each other and see locations on a map where they have crossed paths given that they have both approved each other. The app collects location data from its users, which is then sent to the Node.js server and run through an algorithm to find matches. The algorithm also determines whether or not matches share interests based on those listed on their profiles and notifies the users if they do. Location data for the past week is stored in a MySQL database and is used to generate heat maps of a user's personal location history and the combined location history of every Wander user. The app makes it quick and easy for users to disable all location tracking, should they feel the need, with a manual toggle and the ability to set a schedule of certain times they do not want to be tracked. Never miss another potential connection again with Wander!
