A new app that transmits data via a burst of ‘digital birdsong’ is simplifying the way users share files between smartphones. ‘Chirp’ plays a two-second long noise that sounds like a robotic bird. When this sound is picked up by other devices, it triggers a download.
There are other applications (such as Android Beam, Bump and Dropbox) which allow users to swap material via Bluetooth, WiFi or links to cloud-based storage. However Chirp can send data quickly to multiple devices – without them needing to be paired or connected to WiFI.
