What is chirp?

Chirp is a unique app that lets you share things (like pictures or contacts) – using sound. The app uses special electronic birdsong to ‘chirp’ information over the air to your friends. Every chirp is a little song that links to anything you want to share. Soon we hope to bring out Chirp for Android and all kinds of other platforms to come. The app is free to download and use, making it easy to share data and connect devices.

Why sound?

Sound is everywhere. Because there are billions of little loudspeakers on Earth: in radios, TVs, laptops, phones. So everywhere there’s a loudspeaker, you can put links to useful or interesting or helpful stuff.

How does it work?

You can think of a chirp as a tiny piece of music. Each chirp lasts about two seconds. The system listens out for a couple of dozen notes played rapidly in a certain order, within a certain range, at a certain speed. The audio engine tries to decode the sequence of notes into a sequence of letters which our server understands. The server then returns a link to the user so they can go wherever the short code points: to a webpage, say. This decode all happens in real-time on your phone.


Chirp is commercialised by Animal Systems, a UCLB spinout company.

iGE provides a complete interactive course in English grammar, enabling English language students to develop their knowledge and skills more effectively, and was targeted at students studying the English language at secondary school, high school or university, as well as those who are studying English as a second or foreign language. iGE is written by a team of linguists at University College London (UCL), independently ranked as one of the world’s best Universities. The grammar you’ll be learning is based on recent research and best practice in the field. The app was developed in response to students and teachers who said that many existing learning tools, whether paper-based or interactive, often fail to meet their English language learning needs. Teachers and students are given advice about grammar that is often dated, confusing and, in some cases, highly misleading. The app offers students the opportunity to practise their language skills and study English whenever they want and wherever they are, with further apps for punctuation and spelling planned for the near future. The iGE course covers the same ground as a first year undergraduate course in Modern English Grammar. But that does not mean it is difficult to follow! We have written iGE to make grammar accessible, with clear explanations, colourful notation and lots of examples.
