An app that can tell you the next time you will see someone you just met

An idea for an app that would be really cool for those who don't have a large network of people they know. This app would notice when you meet someone new and asks them a few questions like<br><br>Are you planning to move in the near future?<br>Do you go to the same grocery store?<br>Do you go to the gym?<br>Do you go to church?<br>Do you go to eat lunch in the same place?<br><br>The app would be able to tell you exactly when you would see that person again or tell you how to run into them by accident. You would then get notifications of when you are near the person you met.
