Looking to watch those alcohol consumption levels after over-indulging during the festive period? Well look no further.
Swedish-based Alcosystems has developed a device that works in conjunction with a smartphone app to tell a user just how tipsy they are.
The solution, dubbed iBac, involves a fuel-cell powered breathalyser that sends data via bluetooth to a user's smartphone, giving them their blood alcohol levels on the screen in their hand.
The inventors say the device can be used by both individuals and by organisations that need to check their staff are sober because they might be about to, for example, fly a plane, drive a car, or operate on a patient.
Alcosystems claim that employees working in such roles will be able to assure their bosses that they are the ones breathing into the breathalyser because the app will allow them to submit a photo of themselves and their GPS position, along with their blood alcohol reading.
The app stores results directly on the phone for private users or in a cloud service when used in a commercial scenario.
"Smartphone connection opens up a wealth of opportunities and, besides professional use, it will become as popular among consumers," says Alcosystems innovator, Miguel Arias .
"iBAC is an extremely reliable alcometer that is just a fraction of the size of the breathalysers offered by the company's competitors. One popular feature of the alcometer is that you can keep it with you, on a key ring for example."
Alcosystems claim that the iBac app is already being used by alcohol rehabilitation centres in the US and penal institutions in America.
"Despite the fact that iBac is one of the smallest alcometers available, its results surpass other commercial breathalysers on the market," said Tomas Jonsson, MD at MHF International road safety test lab.
While the iBac app is only £1.49 on Apple's iOS platform and free on Google's Android platform, the breathalyser itself is considerably more expensive at 229 (£190).
