Xiaomi ihealthChinese electronics company Xiaomi plans to launch a new device that allows a user to take his or her blood pressure and see the results on a smartphone.

According to a report:

The sphygmomanometer, or blood pressure cuff, and accompanying phone dock was made in partnership with US-based iHealth Labs.

The device will go on sale in China exclusively on Xiaomi’s official website for RMB 199 (US$32). iHealth also sells a blood pressure monitor in Apple stores, which costs RMB 799 (US$130) in China.

Xiaomi promises the blood pressure monitor will be easy to use and meets all the necessary professional medical standards and certifications. The app, customized for Xiaomi, tracks blood pressure, heart rate, average pulse and more on a real-time chart, then make recommendations for improvement.

DrinkMate – Another Breathalyzer App

DrinkmateWe’re seeing a rush of breathalyzer app devices for smartphones. One is the BACtrack Vio Smartphone Keychain Breathalyzer, which I’ve written about here and here.

Now comes DrinkMate, which is seeking crowdsourcing. Here’s a report on the device:

Washington D.C.-based Edge Tech Labs claim the “DrinkMate” is the smallest breathalyzer in the world. It measures just 1.8 inches long and weighs an almost non-existent 0.2 oz. Users connect the breathalyzer to a smartphone’s miniUSB charging port and blow into an “innovative air inlet” to get their Blood Alcohol Content (BAC) level displayed on screen almost instantly.

The DrinkMate claims to have an accuracy of +/- 0.01% BAC at a BAC of 0.02%. Additionally, the device can measure a maximum BAC level up to 0.20% BAC, which should be more than enough for anyone seriously considering a drive home after a night of heavy drinking.

QardioArm Blood Pressure Monitor – Off To A Flying Start

Qardio blood pressure monitorThe new crowd-sourced Qardio Qardioarm wireless blood pressure monitor is getting some generally good reviews.

PC magazine:

Easy to use. Clear blood pressure readings. Great app. Simple, elegant design.

Not compatible with Microsoft HealthVault.

QardioArm is an at-home blood pressure monitor and app that is dead-simple to use, read, and understand over time. It’s a great device, although because it’s from a smaller company, it might not be compatible with other systems you use.

The Tom’s Guide website:

Smartwatches and fitness bands are getting better and better at tracking your heart rate and blood pressure, but they still don’t provide the type of detailed information that you get when you see your doctor. Qardio is looking to find a middle ground with the QardioArm, which is a compact, $100 blood pressure monitor that syncs with your smartphone to provide you detailed health information anywhere you go.

…Qardio’s unique line of wearable products might not be as sleek as a fitness band, but their vast health tracking capabilities could prove invaluable. The QardioArm allows adults to easily stay on top of their relatives’ blood pressure information, and the upcoming Core could prove useful in both medical and athletic environments.

And a reviewer at Amazon, where, at time of writing, the device has eight reviews and an average rating of 4.5 stars:

Bought this (invested?) in February 2014 as part of early Indiegogo crowd funding. They kept me posted and shipped it to me July 10. I have used it every day and it works great. I have periodic AFIB and the machine detects the changes in bp and AFIB every time. I’m on some bp and arithmia meds and yet try to get out and run and swim frequently. The Qardio Measurements are clearly reflecting changes in my cardiac condition through the day and weeks. Great to have all the data recorded and graphed for review with my doctor. Beautifully designed hardware and software. Really has an “Apple” look and feel experience.

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.
