BACtrack Vio Smartphone Breathalyzer – Pretty Useful to Have Nearby

BACtrack VioI’ve written already about the new BACtrack Vio Smartphone Keychain Breathalyzer. Now come some external reviews.

Here’s 9to5Mac:

BACtrack makes a wide range of breathalyzers, some of them certified for law enforcement use. The Vio is the cheapest one in the company’s range, and is also its least accurate. The device is intended…to confirm a zero reading for ‘morning after’ scenarios, not to provide a precise reading of your intoxication level at anything higher than zero.

The reason for limited accuracy is the technology used in the Vio. Professional breathalyzers use fuel cell technology, and have built in pumps to ensure that all the air is removed from the unit before the breath-test begins. The Vio uses a cheaper semi-conductor based sensor, which is less accurate. This is the only way BACtrack could get the price down to $50.

National Public Radio’s The Salt blog:

It turns out that it’s a bit awkward to operate both blood-alcohol testing device and a smartphone app in a noisy bar with drunk people around you. And if you’re lending the tool to a friend who’s never used it before, it can be hard to tell if he’s blowing hard enough into the device — the likely cause of several faulty readings of 0.0 one of our friends got with the Vio.

The Vio is also a bit fussy. We got a lot of error messages. And the company recommends you use it at least once a month to keep it moist and in working order. 

…All in all, though, a key chain blood-alcohol reader is a handy tool to have around. And we can easily imagine a future where people sign their texts and emails with their BAC: “This email was composed at BAC .06.”

Maybe we should even try that here at The Salt: Over and out, with a BAC of 0.0.

Glamor magazine:

Feel weird having a, uh, breathalyzer on your person? It’s actually pretty useful to have it nearby, just in case, especially on those summer evenings when you head to happy hour (your friends can use your BACtrack too!). Granted, on a day-to-day level, it may be a little weird to have on your key chain—especially when you whip out your keys after a coffee date or a business meeting#8212; but the Vio is subtle enough that it looks like a simple USB drive.

Withings Pulse 02 – Complete and Elegant

Good review of the Withings Pulse O2 activity tracker at Digital Trends:

Withings Pulse 02The Pulse has become one of our favorite fitness bands thanks in a large part to Withings’ detailed, comprehensive and well-designed app Health Mate. Sure, the Pulse can be worn on the wrist or attached to clothing via the belt clip. It does a good job of recording steps and gathering heart rate and oxygen data and it tells the time. The Pulse also monitors sleep well and makes scrolling back through the previous day’s activities a dream. But when coupled with the Health Mate app and other Withings devices like a Wi-Fi scale or Bluetooth blood pressure-monitoring cuff, the Pulse O2 becomes part of one of the most complete and elegant health-tracking systems we’ve tested. And at a time when selecting the right health tracking ecosystem is arguably more important than choosing the best device, buying the Withings Pulse O2 is an easy decision.


  • Full-featured Health Mate app
  • Onboard Pulse and blood oxygen saturation sensor
  • Choice of wristband or belt clip
  • Selfie data sharing


  • No tone or vibration alarm
  • Pulse slips around in wrist strap
  • Button must be pressed to view time
  • Not waterproof

Blood Pressure Apps – Beware, They Don’t Always Work

Wired magazine is warning consumers about a growing number of healthcare apps – including some that claim to be able to take your blood pressure – that don’t work.

Says the magazine:

Iltifat Husain has seen an awful lot of sickness and injury during his time as an emergency room doctor, but lately, he’s worried about something new. He’s worried about the ill effects of mobile healthcare apps.

…To illustrate his concern, Husain points to Instant Blood Pressure, which claims it can take a blood pressure reading in under a minute “using only your iPhone—no cuff required.” The $3.99 app has been among the top 30 most-downloaded apps in the Health and Fitness section of the App Store for the past few weeks, and it features several glowing reviews. According to the app’s description, it “uses a patent-pending process developed by a team from the Johns Hopkins University—a world leader in health innovation.”

The problem is that doctors like Husain have no reason to believe it actually works. There is no public research explaining how the app operates, and the company hasn’t done the kind of study that the Food and Drug Administration would require in ordered to get Instant Blood Pressure cleared as a medical device.

You can find numerous blood pressure apps at Amazon. But you are advised to read the entire article before acquiring any of these.

BACtrack Vio – Keychain Breathalyzer for the Drunk on the Move

BACtrack VioFor the drunk on the move comes the new BACtrack Vio keychain breathalyzer. Like just about everything else these days, it comes with Bluetooth connectivity and its own app thaty allows you to process alcohol readings on your computer or mobile device.

A lengthy article in Fast Company describes the Vio:

Inside the Vio breathalyzer is a sensor attached to a circuit board that measures the change in resistance, based on the number of alcohol particles that hit the sensor when the user blows. About half the size of BACtrack Mobile, the new Vio model uses a fold-out channel the user blows through (with the option to use a mouthpiece accessory) and is powered by a AAA battery. The battery door was flimsy in the early media unit I received, but the company says it addressed the design flaw by mass production time.

The company will continue to sell BACtrack Mobile, which features a police-grade fuel sensor, as a higher-end $129 option aimed at “consumers who are price insensitive who want the best,” Nothacker says. Because of the sensor and a miniature air pump that isolates air from deep within the lungs, he says BACtrack Mobile can be used by professional groups. BACtrack Vio, on the other hand, is intended only for consumer use.

“We’ve been doing this for 13 years, and wanted to design [a breathalyzer] that’s affordable, sexy, that people really want to use,” he said. “We took our Bluetooth board, our alcohol sensor board, mouthpiece, battery space, and we dropped it in a design that minimizes size. Our goal is to make this [something] everybody can bring everywhere.”

Drinking Habits Revealed – BACtrack Smartphone Breathalyzer

BACtrack Smartphone BreathalyzerBACtrack’s Mobile Breathalyzer for smartphones is providing some interesting data on the drinking habits of Americans, according to a company press release.

When users of the device have location services turned on, their breath test readings are collected anonymously by BACtrack.

Based on 12 months of readings from more than 100,000 tests, the company has noted that -

The highest average blood-alcohol content days for US drinkers are – not surprisingly – New Year’s Eve (0.095%), Super Bowl Sunday (0.087%), Valentine’s Day (0.081%) and Fourth of July (0.079%).

Thanksgiving Day usage peaks at 7 p.m., while New Year’s Eve usage dramatically increases after midnight. Meanwhile, Valentine’s Day and Christmas Eve have users drinking earlier in the day than holidays like St. Patrick’s Day and the Fourth of July.

New Year’s Day had the single highest number of unique users and the greatest number of tests - nearly double that of any other day. The next highest day for number of tests was Christmas Day.

Montana and South Dakota have the highest average blood alcohol content results in the country, each with 0.10%. Rounding out the top ten are West Virginia (0.098%), Oklahoma (0.096%), Idaho (0.089%), Vermont (0.087%), Tennessee (0.087%) – and all with 0.086%, Wisconsin, Nevada and Massachusetts.

The five states with the lowest BAC are New Hampshire (0.012%), Delaware (0.026%), Utah
(0.031%), Arkansas (0.037%), and Wyoming (0.051%).

The BACtrack Mobile Breathalyzer Smartphone Breath Alcohol Tester for iPhone, iPad and Android Devices retails for $200, though is currently available at Amazon for $110.

Apple iWatch – Your Personal Blood Pressure Monitor?

Rumors abound that Apple is planning a big announcement soon on a revolutionary new iWatch, with sales likely late in the year. See MacRumors for a summary of the gossip.

For readers of this website, a big attraction will be a range of applications that turn the watch into your own portable health monitor.

According to MacRumors:

Laoyaoba [a Chinese website] also claims that the iWatch will come with a number of advanced health sensors, including those that measure heart rate, blood pressure, and blood glucose. Apple has also apparently developed an in-house sweat analysis sensor for the iWatch, which will all work with iOS 8′s Health app to track various health metrics. 

This information also contrasts a number of past reports that pointed to the iWatch focusing on more simple functionality to make the health-tracking experience more accessible to everyone. While Apple hired a number of personnel with expertise in fields like blood glucose monitoring, it has been noted that such technologies may not make it into the first-generation iWatch, which require a lengthy-approval process from the FDA and complex hardware integration. 

Sony smart watchMeanwhile, rivals are not standing still. A search for iWatch at Amazon yields more than 1,000 products, including the impressive Sony Smart Watch SW2 for Android Phones.

“A Godsend” – Withings Wireless Blood Pressure Monitor

A further good review for the Withings Wireless Blood Pressure Monitor, which I have already written about a couple of times, here and here.

Withings Help Mate appThis comes from the technology page of, and describes the monitor as “a godsend for anyone who has to take their pressures daily or who has to take them while on the road.”

Here is the conclusion of the review:

PROS: Absolutely wireless; iPhone or Android Health Mate app has easy setup; easy to take with you on trips; Bluetooth connectivity to your smartphone.

CONS: One size cuff doesn’t fit all arms; you run the device from the smartphone, so if you don’t have a smartphone you’re hooped.

TO SUM IT UP:  If you own a smartphone – as most people now do – and have high blood pressure that needs to be monitored, then the Withings Wireless Blood Pressure Monitor should meet all your requirements. It’s totally wireless, works via Bluetooth and the App offers a myriad of different measurements that you can actually send to your doctor.

BACtrack Breathalyzers – Saving Lives For 13 Years

I’ve been a consistent supporter of BACtrack breathalyzers over many years, in several websites. Their products are generally sound, and their cheap prices have meant that these are no longer products only for the professional.

BACtrack Keyring BreathalyzerI have little doubt that BACtrack breathalyzers have saved many lives.

The company is celebrating its 13th anniversary.

In a press release it says:

When BACtrack was founded in 2001, breathalyzers were primarily for law enforcement use and costs were high. Keith Nothacker, CEO and Founder of BACtrack, recognized that someone could be arrested and sent to jail with a Blood Alcohol Content over 0.08%, but that the general public had no way to actually test and measure their own BAC. As an undergraduate student at the University of Pennsylvania, Nothacker developed the first line of consumer breathalyzers.

In 2004, BACtrack was the first company to ever receive U.S. Food & Drug Administration 510(k) marketing clearance to legally sell breathalyzers to consumers for personal use. Since then, the company has worked to simplify the product, reduce the cost of the technology, and increase consumer awareness.

Today, BACtrack offers a wide range of breathalyzers for both personal and professional use and they are used by consumers, businesses, schools, clinics, hospitals, law enforcement, and even the U.S. military around the world.

In April 2013, BACtrack launched the BACtrack Mobile Breathalyzer, the first smartphone breathalyzer to combine professional-grade fuel cell sensor technology, Bluetooth connectivity, and app-enabled features. With BACtrack Mobile, users can obtain a BAC result, view safety information, and monitor how alcohol affects the body at each BAC point. The ZeroLine feature also shows a user approximately how long alcohol will remain in their bloodstream after consumption.

BACtrack’s suite of products continues to be recognized by top research and media publications. BACtrack is featured in the 2013 December issue of Popular Science and the BACtrack Mobile Breathalyzer received the 2013 Best of What’s New Award (Popular Science’s top honor) for its innovation in health. Popular Science stated BACtrack and the other award recipients are “poised to change the world,” and they “challenge us to the see the future in a new light.”

“Stylish and Moderately Priced” – Withings Wireless Blood Pressure Monitor

Withings-Wireless-Blood-Pressure-MonitorI have already written about the new Withings wireless blood pressure monitor, and now another good review comes from the MedGadget website.

The conclusion:

Having an easy to use blood pressure monitor can help improve compliance of patients that should be taking regular readings. The Withings Wireless Blood Pressure Monitor is stylish and moderately priced, intuitive to use, and is kind of fun compared to drug store models. The additional advantage of Withings is that combined with data collected by its other products, in a single graph you can visualize readings from their smart scale, activity tracker, and sleep monitor combined with the blood pressure readings from this device. Emailing such data to your doctor is easy and shows a real step toward the type of medical management that will conceivably be ubiquitous in the future.

The device is now available at Amazon (it wasn’t when I wrote my original report). Check this out for user reviews and for the latest price.
