Babies are unable to speak in a language that adults can fully understand, and instead communicate their needs through crying. While many parents are often able to distinguish the meaning of their baby's cries, that is not always the case. Now, there is a handy iPhone app that promises to tell you why your baby is crying.

A company based out of Barcelona recently launched an iPhone application that they say tell you why your baby is crying in just 10 seconds. Dubbed "The Cry Translator", creators Pedro Barrerra and Luis Meca say the app "involves a revolutionary technology that quickly identifies an infant's cry, based on one of five emotional or physiological states: hunger, fatigue, annoyance, stress or boredom".

The creators say:

'These five cries are universal to all babies regardless of culture or language.'

So how does it work? Parents are instructed to place their iPhone about a foot away from the crying baby and then press the "Start" button. The cries are then analyzed and identified within 10 seconds with a 96 percent degree of accuracy. After the cry is identified, tips are then given on how to remedy the situation and calm the infant.

The technology was initially developed using a handheld device, but the company later decided to simply create on bringing the technology to an iPhone application.

It was tested in a clinical trial at a hospital in Spain. The original device was used in this instance on 104 children, and when the suggestions on how to calm the child were followed, 96 percent of babies stopped crying.

The app is available in the US, Spain, and the UK and is priced at $9.99.
