Radar is a free iPhone App for group picture and video sharing integrated with Twitter, Facebook, Flickr, and other social networks, that lets you post, browse, and comment. The Radar app for iPhone and iPod Touch offers video streaming, advanced caching for quick launching, and progressive download of content for fast browsing and commenting, even when network speeds are slow.

Radar is a photo sharing site and does a good job of just sharing pictures among your friends. The service is run by Tiny Pictures, a San Francisco startup. Whenever you snap a picture you want to share, you send it via e-mail from your iPhone to the specific Radar email account you get when you sign up for the first time. The photos then appears immediately online, and everyone you’ve invited as a friend can see the pictures and comment on them. Additionally, Radar supports streaming video for clips shared on the Radar network.
