Bands to barcamps, it’s all at your fingertips. Once you sign in using your Upcoming account, your Friends’ events are there for your perusal.

Aloqa
Aloqa is a mobile service that proactively notifies users about social opportunities such as Facebook friends close by, and recommends interesting places, services and events in their vicinity. Once you download and start Aloqa, you need to just look at your phone and it shows you constantly refreshed, live information about people, places and events based on your location, profile, preferences and social relationships. Aloqa is very good at “pushing” interesting notifications to your phone based on a rough understanding of where you are in real time, but without ever recording where you are.
