Six Overground announced the release of dropdrop 1.1, a new iPhone app that lets you leave "drops" where you travel for others to discover.

dropdrop: An App that allows you to Leave Virtual MessagesA drop is a message or photo placed at a specific location in the real world. Missed that cute stranger on the train platform? Leave an anonymous drop for them to find when they return. Want to plan a pickup game in your area? Create a drop, set its size to your neighborhood, and see who responds. Have something to sell that needs to be picked up? Take a photo, leave a drop that covers a reasonable driving distance, and anyone in range will see your listing. New to the area and need some local tips? Look for drops around you for ideas. Want to get creative? Leave drops with hints for another location, and play a scavenger hunt with your friends.

This is the first time people can create user-generated geofences for communication. We're talking about messages that live at a real-world location, with a defined radius, lifespan, and visibility. Think Bluetooth beacons without the hardware. You determine the size of the drop, its duration, and who can see it. Don't want anyone to know who left it? Spend stamps and leave an anonymous drop. Everything on dropdrop is centered around location, so drops are relevant and timely. Drops don't last forever, so the conversation stays fresh.

dropdrop-exploring-deviceWhen creating a drop, it's placed exactly at your current location. You can set drops to cover the size of a room, a building, a neighborhood, or a city. Drops can be set to last between one day and 60 days. After that, the drop is gone forever. You can also select from a list of your friends so that the drop is only visible to them. When a friend approaches the edge of a drop, they'll receive a notification on their phone that a drop is in their immediate vicinity. Drops can also be left anonymously by spending stamps (currency that can be rewarded or purchased in the app).

Features:
* Leave drops for the world to see, or limit visibility to select friends
* Choose the duration of a drop before it disappears
* Select the size of a drop - as small as a room, or as big as a city
* Post with your public profile, or opt to post anonymously
* Get notifications when you discover drops nearby
