So imagine if being on a long flight and as usual you kick back and enjoy some on board alcoholic refreshments. Well a couple of glasses in you realize that you will be landing in a few minutes. Since you wouldn’t want to face security officials intoxicated we can recommend the smartphone breathalyzer.
Compatible with iPhone and Android devices, the BACtrack Vio Smartphone Keychain Breathalyzer is a fun and affordable way to estimate your Blood Alcohol Content (BAC). The gizmo is shaped like a USB flash drive and connects to your smartphone via the free BACtrack app. Be aware though, this breathalyzer doesn’t have a professional-grade sensor integrated, so don’t use it to judge whether or not you are sober enough to drive.
