Unless you don’t actually drink, it sucks to be on a night out and be the designated driver. Or if you are going to be drinking, how do you keep track of your alcohol level and make sure that you do not exceed the limit and get yourself caught for drunk driving or worse, endangering yourself and others? The BACtrack Vio Keychain Breathalyzer is a handy device that actually allows you to measure your Blood Alcohol Content (BAC) at an instant.
The BACtrack Vio Keychain Breathalyzer works just like a normal breathalyzer. Just flip out the folding mouthpiece and blow into it. Here comes the interesting part. The device connects to your iPhone or Android smartphone via Bluetooth, analyzes your breath sample and gives you a reading. So you can either do constant measurements to make sure you don’t go over the limit or make a quick check before you actually drive off in your car.
If you accidentally went over the limit, the app will even give you an estimate of how long you have to wait before your BAC goes back to normal. You can then decide if you should wait it out or just take a cab home. BACtrack Vio lets you drink responsibly and keeps you safe.
