The app puts a new twist on preferences aggregation and analytics by alerting users when an unwanted person is nearby, calculating their chances of bumping into them, and advising on how best to avoid an encounter. Split uses public data including check-ins, location indicatorsand anyother geo-tagging in posts, andlocation inputs provided by Split users themselves.
