Facebook posted a news on 17 April 2014 that it is going to roll out a new Location Sharing feature on iOS and android phones called Nearby Friends that’ll help you to meet with your nearby friends. The feature is optional and requires two-way approval, so you as well as your friends would have to explicitly activate it from Facebook settings.
For this you need to turn on this feature from your account setting. If you turn on this, you will be notified when friends are nearby you so you can get in touch with them and meet them. For example, when you’re headed to the movies, Nearby Friends will let you know if friends are nearby so you can see the movie together or meet up afterward.
It is a optional feature means you can choose who can see you, if you are nearby and also you can turn on or off any time this feature.
You can share location only when you and your friends both have to turned on Nearby Friends and choose to share with each other when you both Nearby. Your friends will only be able to see that you’re nearby if you share this info with them and vice versa.
This feature is available in several apps, including Foursquare and Find My Friends, but Facebook naturally wants its own app to have these location-based social features.
