The most accurate & true 24/7 fitness wearable

CloudTag Inc (CTAG:LON) is a London Stock Exchange AIM listed company bringing accurate, medical-grade technology to the consumer health, wellbeing and fitness markets. CloudTag brings together world leaders in nano-electronics, medical technology, exercise and sport science, software development, mobile commerce and data analysis. 

CloudTag’s first product – a wearable fitness tracker that measures heart rate, energy expenditure, steps and many other metrics and can be worn on both the wrist and the chest – is founded on ten years of medical research, bringing proprietary sensoring technology both contact and contactless sensors to market and will be initially targeted at the weight loss and fitness markets.

“If the heart rate monitor on this next-gen fitness tracker is as accurate as claimed, I reckon some of the leading brands will be spilling their coffee in the boardroom..”

Was the quote that resonates with me after reading Urban Wearables preview on the CloudTag Track back in May.

I wanted to introduce myself and have a catch up with Urban Wearable’s and asked  what they thought was the best all-round fitness tracker available to buy at this moment in time.

I spoke to Richard, the editor and founder of Urban Wearables who saw the potential in wearable tech a few years back so started Urban. 

“Skeptics were saying “wearables are a dumb idea and would never take off”. That skepticism has receded back into the shadows now though. For me it was a case of simply putting 2 and 2 together: “people aren’t going to stop wearing things + technology isn’t going away = wearable technology is coming”

I thought to start of by asking the most basic;

“Which wearable would you currently recommend as the best all rounder? Accuracy, battery, comfort & style?”

UW : “That’s quite a difficult question as there is such a mixed bag of features. In terms of wrist-worn fitness wearables; Fitbit and Garmin sell the most. I would say the best all-rounder would be the Garmin Vivoactive HR+, although the Fitbit Blaze has the advantage in the “style” department.”

Despite the best efforts of companies like Fitbit and Garmin, their optical heart rate monitors leave a lot to be desired in terms of accuracy. They’re pretty accurate for measuring the resting heart rate, but for high intensity workouts, running, etc, they aren’t so accurate. If the CloudTag Track can provide the accuracy that lacks in the Fitbits, Garmis, ect, I think it will be popular.”

Something that consumers often look for in fitness wearables, is third-party app compatibility. This is because they might have been using a fitness app such as Strava, MyFitnessPal, MapMyRun, etc, for the last year and want to continue using it. The ability to integrate their existing fitness data/history with their new fitness wearable’s app means they don’t have start all over again.”

Fitbit have greater third-party app compatibility than Garmin, although Garmin have woken up, smelled the cheese and are opening up.”

From what I can see, the USP of the CloudTag Track will be its HRM accuracy and the weight loss thing – but it seems like the company already know this..”

The Cloudtag Track stands out from the bunch as it uses advanced ECG sensors to obtain clinical-grade results for heart rate, energy expenditure and calorie output.

Another thing that differentiates Cloudtag Track from the competition is its innovative design and beatSMART clip that allows it to be worn on the wrist as you’re going about your daily bustle, and then worn on the torso close to the heart when exercising. From a BPM accuracy standpoint, this makes perfect sense. 

The app provides a personalized fitness and nutritional program and relates directly with the user by constantly adapting to your fitness and weight loss progress. By entering your weight into the app on a daily basis, Cloudtag will be able to predict how long it will be before you can fit into your favorite suit or dress that’s been hanging in the closet since the summer before last, or whenever you were last shapely enough to wear it..

Within the Cloudtag app you’ll have access to 350 (and growing) exercises developed by professional coaches and personal trainers, plus, a wealth of nutritional information with international weight-loss icon, Jessie Pavelka as an ambassador of the program.

Richard had the idea to create his own wearable about two years ago, but it didn’t seem like the right time. Now wearable’s has arrived on the mainstream market he is finalizing the spec sheet for developing his own wearable tech product that has the potential to be very successful which will be focusing on a health, body & mind wearable tech product for females, but in a different way than anything else available on the market. Richard assures me that the product slots into a different category to the CloudTag Track and won’t be seen as a competitor.

What’s fascinating about the CloudTag Track is that you never have to be without it, because of its dual-use.

Wearing the device in the beatSMART clip for one hour gives a full charge for three to five days on the wrist, a truly 24/7 device.

The incentives for commercial weight watching companies to encourage users to do at least 1 hours exercise every 3 days is for me, one of the biggest USP’s

“University tests on CloudTag‘s proprietary sensors, electrodes and algorithms have shown heart rate tracking to be between 98% and 99% accurate in comparison to a clinical electrocardiography (ECG) machine during walking and running activity.

Energy expenditure (kilocalories) tracking results show correlation between 91% and 99% against the medical gold standard measurement, a cardiopulmonary exercise (CPX) metabolic cart.”

Accuracy, accuracy, accuracy .. 

Every single article, blog & person that I have spoken too about fitness trackers and health wearable’s have told me that the most important aspect of the device is the accuracy of data provided back to the user.

However, there seems to be a significant discrepancy between what the devices report and what the actual number of burned calories is. The average margin of error is around 200 calories per day or 1,400 per week!

A study by JAMA shows that researchers noted a few factors that might have contributed to the disconnect, including the fact that participants couldn’t wear the trackers all the time. They also noted that they tested only a healthy weight population, and that future studies should include overweight participants as well. The devices that were used consisted of 12 popular consumer devices; 

Fitbit Flex, Jawbone UP24, Misfit Shine, Epson Pulsense PS-100, Garmin Vivofit, Tanita AM-160, Omron CalorieScan HJA-403C, and Withings Pulse O2) and devices more often used in healthcare (Panasonic Actimarker EW 4800, Suzuken Lifecorder EX, Omron Active style Pro HJA-350IT, and ActiGraph GT3X.

The readings from these devices were compared to two more robust ways of tracking calories. In the first experiment, the participants spent 24 hours in a metabolic chamber where scientists could track oxygen consumption and carbon dioxide production, and assess calorie expenditure from that. In the second, researchers used urine samples to calculate participants’ calorie expenditures in their normal lives.

In the metabolic chamber test, the Withings and Jawbone devices underestimated expenditure by about 270 calories while both Omron devices overestimated calories by about 200 calories. The other devices all fell in between that range, with the Panasonic and Epson devices the closest to the standard.

In an accompanying commentary, Dr. Adam Schoenfeld, an internist at UCSF, wrote about how this study demonstrates the need for FDA regulation of mobile apps that are going to be used as medical devices. 

“Use of health-related apps may pose little risk in healthy persons if the information collected is not used for medical decision-making, but these apps should still undergo basic testing for accuracy,” he wrote. “For mHealth apps that are designed to play a role in medical care, documenting the validity and accuracy of measurements is crucial.

Fitbit, Garmin, Jawbone Highly innacurate

NewsChannel 5 on Your Side decided to find out with three of the most popular trackers: the Garmin Vivofit, the Fitbit HR Charge and the Jawbone UP3.

We read the instructions and calibrated each model accordingly.

With the help of an KSDK executive assistant named Monica we documented a carefully counted 250 step hike.

Monica wore all three of our trackers.

But at the finish line, we had three different results.

Monica’s 250 steps- were only 179 steps according to the Jawbone. Seventy one steps short!

The Fitbit did even worse- only showing 157 steps, or 93 steps short

And in third place? The Garmin tracker- which didn’t count 105 of Monica’s steps

Then we went to Missouri Baptist Hospital and their Cardiac Stress Lab.

“A lot of our patients wear them. They want to make sure their heartrate is not going too high when they’re exercising,” said Barbara Rogers, a Cardiac Stress Nurse at Missouri Baptist Hospital.

We suited up, to test out another Fitbit function- at the center of nationwide class action lawsuit.
I was hooked up to an EKG machine so Rogers could compare my actual heart rate to what the Fitbit said.

For 20 minutes, I jog, run and walk. All the while, we get a variety of readings…

But soon a pattern became clear, the Fitbit kept low-balling my actual heart rate.

At a fast walk — the EKG said my real heart rate was 124. The fitbit: 117.

Jogging? 136 beats a minute became 126 according to my wrist.

And flat out running: my heart pulsed at 179, but Fitbit told me I was at 150.

Our results are similar to what other studies found. Like a recent study from California State Polytechnic University that found Fitbit heart rate measurements can be “highly inaccurate” .

And some worry such an inaccuracy could have serious consequences.

“They could exercise at an intensity that would put them at risk for medical complications during exercise,” said Dr. Weiss.


Judging by “The Perfect Wearable” The CloudTag Track seem to tick all of the right boxes with its hyper personalised adaptable programming, support focused on goal date whilst dynamically adjusting according to user’s progress, true 24/7 wearability, easy to follow Nutrition advice, high quality proprietary workout videos and expert designed instruction in a home environment, multiple options to wear the device – either discreet or on show, connectability with health care providers, insurers and social media.
