Find My Friends has received a small, but important update. Version 2.1 of Apple's friend-location software introduces a new UI to search and set location-based notifications. Paranoid that your child is skipping school? Use the UI to look for your child's school and get alerted if he leaves before he should.
The Next Web has played around with the release and notes that the new UI allows you to set an exact distance from a location, so it's more useful for doing things such as locating someone a short distance away from you. Tap and drag on the location to set the parameters desired.
