iPhone app Chirp can transfer images, text and web addresses between two phones that are in the audible range. The transfer takes place by means of sound signals that sound like they are made of a robotic bird.
Chirp app is simple to use. After you’ve selected a picture or written a note or a URL, tap a large yellow button to start sending. After a few seconds with “bird noises” from mobile phone to mobile phone you will have sent the file on all iPhone devices nearby that have Chirp app open and can “hear” your data chirp
Even though the transfer takes place by means of audio signals, you still need an internet or 3G connection for the app to work. If you capture an image to transfer by chirps it will be downloaded from the chirp server as this method makes sending images possible.
When you choose to “chirp” a picture is that the image is uploaded from the mobile phone to the chirp servers. As soon as you press Chirp button to send the picture, you would have sent the link to the image (rather than the actual image) to the other phone. The Chirp app will then download the picture from this link and show it on the phone. It looks as if the image is transferred directly, but in reality we are talking about an exchange of links and an upload to Chirps servers of the image
“We’re called Animal Systems because, well, we look to nature for inspiration,” explains CEO Patrick Bergel. “Specifically, we’ve been looking at how biology encodes information, in this case, and playing around with various related ideas, all with mobile as the starting point. Chirp was the best idea, so we went with that.”
