BACtrack was founded back in 2001 and since then has been providing high quality breathalysers for both personal and professional use. The devices use specialized technologies which measure the blood alcohol content or BAC to the highest degree of accuracy possible.

Bactrack Mobile Packaging

The BACtrack Mobile is a tiny breathalyser that can be paired with your smartphone whether it’s an Apple or Android device. The device measures just 1.75 x 2.75 x 0.63 inches and weighs a mere 1.7 ounces meaning that it is ultra portable to the point where you can slip it into your pocket while you’re on the go.

You would normally expect to find a small display on the device, but not on the BACtrack Mobile. The device uses Bluetooth 4.0 which is compatible with all the latest smartphones including the iPhone, iPad and Android phones. It sends all of the information via Bluetooth to your device where it then displays via the app you can download.

The body is manufactured from plastic, and the breath chamber is also partially transparent allowing you to see the inside of the device. A small metallic button on the edge of the body acts as the power on/off.
The real technology is inside this miniature breathalyzer. The sensor technology used is an Xtend™ electro-chemical fuel cell, which can detect even the smallest amount of alcohol, down to 0.001% to be exact. It’s in fact the very same technology that is used by the police.

Bactrack Mobile Device

To use the mobile device you must have the application installed on your phone, otherwise you’ll just be wasting breath. Pairing the breathalyser with your phone is simple and is done using the app. Before you can give a sample the device needs to ‘warm up’ and this can take anywhere between 5-10 seconds. You then need to breathe for five seconds into the breath chamber, the device will click and that’s it.

The results are sent to your mobile device where they are analysed and displayed. It will state what your BAC level is in large characters as well as estimating what you’ll be feeling.

There are a few more features included in the app as you continue through the screens including the opportunity to add a location, add pictures, notes and then save it all. A feature we really love is that it will attempt to estimate how long until you sober up. This is nicely displayed in a graph for easy viewing.

Bactrack Mobile & Case

One feature we’re not too keen on is the choice to share your stats on social media and via SMS. Although if used correctly it could be quite fun to compare friends results, but to us it is more likely to turn into a competition to see who can get the highest score/BAC reading.

In the box you’ll also receive a couple of plastic mouthpieces which you can insert into the breath chamber if you’re not keen on just passing the device around without taking hygiene into account. You’ll also get a micro-USB cable which you can use to charge the device’s battery.

Our Verdict

The internals of this device are on par with professional grade equipment and BACtrack have managed to squeeze this into a tiny body that’s ultra portable. Paired with the iOS/Android app, you’ll get a whole bunch of awesome features as well. We’re not too keen on the social side of the device and we also think the $150 price tag will put some people off.

If you’re looking for something a little cheaper, but will still impress all of those around you, it may be worth while to check out the Keychain Breathalyzer which costs just $30!
