Clustr - The Social Compass

Find Facebook friends near you anonymously and in real-time:

Eliminate the feeling of FOMO.
Share your location with a few people only when you want to - don’t publicize it.
Ask a friend for their location.
Never text someone what’s up again.

Steps:
See where groups of your friends are on the Clustr map.
Tap on friends to ask them to reveal who they are.
See each other on the map for an hour.
Send them a message and meet up!
