PostInPlace

A free, location-based, proximity-sensing app for iPhone that lets you browse social media around you and enables you to post text, photos and web links to your devices location. With PostInPlace you can leave information for others to find.

Using your devices location (requires location services) you can browse available public location-based social media posts (Twitter, Flickr, Panoramio and Wikipedia are currently supported) as well as text messages, photos and links posted to the PostInPlace service. With a free PostInPlace account you can place text messages, photos and links at your devices location. Posts can be publicly viewable or private to yourself and your friends.

PostInPlace is a simple, open platform for creating and browsing location-based information.
