Originally published on September 23, 2013 <br /><br />Drivers can now test their blood alcohol levels with new smartphone apps that give accurate readings and can also call a taxi. A blood alcohol level above 0.08 percent is considered drunk driving in all 50 U.S. states. <br /><br />BACtrack for iPhones and Breathometer for iPhones and Android are two examples of these types of apps. <br /><br />Breathometer connects via the mobile phone's headphone jack, while BACtrack connects to the iPhone via Bluetooth.<br /><br />Both devices work by having the user blow into it. An ethanol sensor embedded in the device detects alcohol on the user's breath and converts this into a signal that the app processes.<br /><br />Both apps not only display alcohol readings, but can also detect a user's GPS location and call a friend, family member or taxi should they be found to be over the limit.<br /><br />The apps also estimate how long it will take for users to sober up and provides a drinking habit graph.<br /><br />--------------------------------------------------------<br /><br />TomoNews is your daily source for top animated news.
