Chirp is a free app on the iOS store, specifically for iPhone but can also be downloaded for iPod Touch and iPad with no real effect on the user experience.
Its classed as a ‘social networking’ app by iTunes, but isn’t your usual Twitter or Facebook, although it does include integration with both of these services.
This app uses sound to send data from Phone to Phone. I had this set up with 2 iPad’s in my house and used it to send notes, links, pictures etc. When you open up the interface you can choose what your looking to send, the app then changes this information to a sound wave and plays the ‘chirp’ through the devices speaker, the other device picks this noise up via the microphone and translates it back into what it should be, i.e a picture or a note. For the devices to register and translate the chirp, the app its self must be open, so it will not translate chirps if the app is open in the background.
Of course there are numerous advantages as well as disadvantages with this,
This could be used on a large scale e.g played through the speakers at a local supermarket giving shoppers voucher codes or special offers, or it could be used in a room full of people to quickly send and share photos or links with everyone.
On the downside, playing chirps as a way of sending messages in a public place means anyone with the app open can intercept the message and have a nosey into your conversation or steal your images !
This, I see more of an innovative creative kind of new tech. This shouldn’t have holes poked in it due to its lack of security in public places, it should be praised as somebody thinking outside the box and not making another repetitive ‘freemium’ game. This app may be the first of this sort of technology but could become mainstream with numerous applications outside the app world being possible..
