Apple rolled out an update for its Find My Friends app for the iPhone on Thursday that lets users set exact locations for notifications. Find My Friends is Apple's own location-based app and service for seeing where your friends and family are, and for receiving notifications when they happen to be nearby.
The version 1.2 update lets users set exact locations for notifications, as well as distances from those locations, which comes in handy when you want to know when someone arrives at or leaves a specific location such as work or school.
Find My Friends
Find My Friends is free and available at Apple's iTunes-based App Store.
