How many times did you find out your friends were just next to you? In a show, in the pub or in a commute? DropBy is a background service that allows you to be informed when a friend is nearby. A push message will give the alert and both can chat to arrange a meeting or just to say hi.

You can also place and receive geo-localized messages. Broadcast your message in a simple step. Any passing user can receive the message and start a group chat. Do you love the pub you're currently in? Just drop a message and get the community involved.

BATTERY CONSUMPTION
DropBy is smartly designed to update your location only when you're moving, limiting the GPS usage. However, please beare in mind that :
Continued use of GPS running in the background can dramatically decrease battery life.
