An update on the Quantified Self

In this article, we check up on the current goings-on in the realm of QS.

A few months back, we put together a series of blogposts on the Quantified Self. We’ve had a look around at what’s been happening in the QS field in the meantime, and have put together this update, with some interesting new apps, products and articles.

Apps and gadgets

TenXer is a personal assistant startup, founded by Jeff Ma, who as it happens was a member of the MIT Blackjack Team. It aims to increase your productivity at work by helping you track your progress in relation to set goals. RescueTime, a competitor, operates under a similar concept, monitoring your computer activity to give you feedback on how you’re spending your time.

Alohar is a platform that includes a software development kit for Android and iPhone, and services that gather detailed data on location (how many times you’ve been there, how often you usually stay) and movement. Applications for this information could be both QS-related and commercial.

HealthyShare is the product of a cooperation between Facebook and General Electric. Just in time for the Olympics, the two giants bond for a piece of the QS cake, in the form of an app that provides the user with a selection of Olympian-sponsored challenges to promote good health.

Lift is an iPhone app designed to help people achieve any kind of goal, big or small. This startup with the rather ambitious desire to “eliminate willpower as a factor in achieving goals” has been backed by Twitter’s founders and is set to launch in August 2012.

Samsung S Health, an app for the Galaxy S III phone, allows users to track their weight, blood sugar and blood pressure levels.

Nike and Microsoft have come out with Nike+ Kinect Training, an exercise program for Xbox 360. Combining two hugely popular platforms, this could be big.

The Garmin Swim watch (article in German) is designed for swimmers to keep track of their exercise.

What we read this week (25 May)

Our reads this week: whether Facebook can be successful in the long term, how the mobile internet affects our approach to healthcare, what companies should focus on when recruiting, a new community for maker-minded kids, and insights on businesses operating at the intersection between technology and culture.

Quote of the week

The Singularity has always sounded to me like a secular version of the Rapture. It seems to fit very neatly into that same God-shaped hole.

William Gibson

Articles of the week

  • Bud Caddell: Emerging Bets at the Intersection of Technology & Culture
    Bud Caddell from Deutsch LA took his team of innovation strategists to SXSW this year to study all the startups launching there. They aggregated all their insights and put them into this report. It’s a great overview about current trends in the US startup world and what marketers can learn from them.
  • Fred Wilson: Culture and Fit
    Fred Wilson, head of Union Square Ventures, discusses some common mistakes made in companies’ hiring processes, and where the focus should really lie: culture and fit should be prized above talent and renown.
  • Technology Review: The Facebook Fallacy
    Michael Wolff explains how Facebook is not only on course to go bust, but will take the rest of the ad-supported Web with it. A controversial and compelling case on the state of affairs of ad-based online business, and why current methods cannot be successful in the long run.
  • O’Reilly Radar: Parsing a new Pew report: 3 ways the Internet is shaping healthcare
    Pew Internet and Life Project recently coducted a survey on how people inform themselves about health. Alex Howard breaks down the study’s findings into three key trends: Quantified Self, participatory medicine and what he calls the ‘new digital divide.’ Mobile health data, it seems, is particularly helpful, but in the hands of people who aren’t as likely to need it. The article prompts some interesting questions about how we could make this kind of information more accessible.
  • New York Times: Disruptions: A Beacon to Silicon Valley, From a Start-Up for Children
    Since our conversation with Zach last November, we have been eagerly awaiting the public appearance of his new venture. DIY is here and it is shaping up to be an interesting community for kids who make things. The kids post pictures of their work online, and can find inspiration in users’ projects, from melted crayon paintings to soda bottle rockets. It’s nice to see the Internet evolving in a way that appeals to a different age group.

Quantified Self Data & Privacy

Tracking our behaviors and our body data means tracking the most sensitive kind of data. This is the very thing the privacy debate is about: Health and location data. So let’s think about this.

This article is part of our series on the Quantified Self.

Quantifying ourselves means tracking the most sensitive kind of data: Our behavior and our location.

The conversations we have on a day-to-day basis about body tracking and the Quantified Self clearly show that most people are acutely aware of just how sensitive this type of data is. In fact, privacy implications tend to be one of the first issues to come up.

And this most certainly isn’t just an exaggerated reaction, but rather the sensible thing to think about. But let’s take it step by step.

Our most sensitive data

In theory, tracking and “optimizing” ourselves lead to better life decisions – in other words, to be more ourselves. However, disclosing exact data about our bodies and our whereabouts makes us vulnerable. The potential for abuse is immense.

Now there are several aspects to look at:

  • What kind of data do we capture? This is largely determined by the types of services and devices is user.
  • Where is the data captured? In most cases these days our data sets are stored in the cloud, not locally. This makes it easier to handle and backup, but also more hackable and commercially exploitable. In most cases, the cloud is the right place to put this data, but I’d imagine there’s a business case to be made to allow users to store data locally. Some people might even pay a premium.
  • How do we share our data? The spectrum ranges from publishing our data sets in full, publicly and non-anonymously (this is roughly where Foursquare is), to highly anonymous aggregated data (medical data). More on that later.

And of course: Who is interested in our data?

Who wants our data?

There are quite a few players out there for whom our data is highly valuable – often in a straight-forward financial way.

Marketing departments are obvious in this context, as behavioral data creates opportunity to target potential customers, and build relationships. This could be used in “white hat” marketing, ie. in non-critical ways that actually creates value for consumers. It could also be done “black hat”, ie. in abusive ways. Think data mining gone awry.

Researcher of all flavors are interested in the kind of data sets created through self-tracking.

Governments might be tempted by location and mobility data, and try to match social graphs, location overlaps, group behaviors.

Insurance companies might see behavioral data as gold mines. Depending on your country’s legal and social security framework, health insurances might charge customers differently depending on their fitness regime, or smoking behavior, or regularity of their heartbeats, or the number of drinks per week, or even the numbers of bars visited. Maybe the types of meals eaten and calories consumed, or body weight. In this particular context the possibilities for use and abuse are endless.

Which brings us to…


Where we deal with sensitive data, trust is key. We, the consumers & users of web services, have collectively suffered privacy missteps by internet companies and over-zealous startups over and over again. (I’m looking at you, Facebook!)

While many of us have gotten used to sharing some aspects of our social graphs online, behavior data might be a different beast altogether.

This isn’t just a matter of degree, either. Here we have such clear abuse scenarios that insisting on control over our data simply becomes commons sense.

As researcher Danah Body states (highlights are mine):

“People should – and do – care deeply about privacy. But privacy is not simply the control of information. Rather, privacy is the ability to assert control over a social situation. This requires that people have agency in their environment and that they are able to understand any given social situation so as to adjust how they present themselves and determine what information they share. […Privacy is] protected when people are able to fully understand the social environment in which they are operating and have the protections necessary to maintain agency.”

Take Facebook for example. Recently, the company introduced what they call “frictionless sharing“. What that means is that all kinds of apps and services share your activity on Facebook – which song you’re listening to, which articles you’re reading, what you comment on etc. While the announcements drew quite a bit of criticism, we can only assume that the increased sharing activity will serve the company’s goals well: It will create more engagement data, at the cost of privacy and control. In other words, at the cost of agency.

What this means for companies operating in this field is this: It must be absolutely clear that they never, ever share your behavioral data with anyone without your clear consent. More bluntly: If you don’t actively share your data with anyone outside the company, they must not do it.

Here I’d even go so far as to suggest thinking about worst-case scenarios: Maybe it even makes sense for some companies not to even store your data but instead save it on the client side, so that they could not even be subpoenaed into giving up user data.

Do I even have to mention that a strict and very easy to understand privacy policy is a must?

So, now that we have reduced the potential for abuse a bit, the next question is…

Who owns our body data?

Now here’s a question that’s both very simple and incredibly complex. As a guideline, the ideal we should always strive for is: We do! Nobody but ourselves.

However, it’s of course a bit more tricky. The service provider will need some of the data for their business case. Expect not to get anything for free. As the old internet proverb goes, you either pay or you’re being sold.

So we have data ownership and usage rights on one hand, and then we have data portability.

Let’s say we upload our running data into Runkeeper, track our meals with The Eatery, our sleep patterns with the FitBit or the Jawbone Up, and our social life through Foursquare. That’s already quite an array of services for even a basic tracking setup.

If history has taught us anything, then it is that web services don’t live forever. So we need to be able to get our data back when we need it. Better still, we should be able to move our data sets from one service to another, combine and mash them up, and allow different services to access our data in ways we can easily control. Easy is key here as we move towards mainstream adaption.

A simple data dump won’t necessarily do – the data has to be structured, maybe even standardized. Only then can we use it in new, interesting ways.

Sharing ourselves

A hypothesis: Collecting behavior data is good. Sharing behavior data is better.

Bigger data sets allow us to derive more meaning, potentially even to create more data from what we have. The kind of data we talk about becomes immensely interesting once we start thinking in terms of scalability. Think two people comparing their fitness data is cool? A billion people comparing fitness data is cool!

To protect the individual, aggregated and anonymized data is the way to go here. Aggregated data sets still allow us interesting correlations while providing some level of protection. Although even aggregated data sets can be tricky: A study found that 87 percent of the people in the United States were uniquely identifiable with just three pieces of information: gender, date of birth and area code.

Sharing isn’t a simple process, either. As Christopher Poole pointed out in fantastic talk, most current models of online sharing assume that you have one identity and that users just need to be able to determine which bits of information to share. In reality, though, it’s much more complex. Our identity online should be like in the physical world – multi-faceted, context-dependent. It is not, in Christopher’s words, who we share to, but who we share as. This is hard to put in code, but it’s important that we think about, and hard.

Context is key in sharing. I might no be willing to publicly share my brain activity, heart beat and genetical information. However, I might be very willing to share parts of either of these with my doctor while in treatment – as long as I can be sure that the doc won’t pass it on to the insurance so they charge me extra for higher-than-average genetical chance of some kinds of cancer or Alzheimer’s. Today, most doctors or even larger clinics aren’t even able to make use of the type of genetical snapshot commercial services like 23andme, although this might change over time.

A duty to share?

In a radio interview recently we discussed privacy implications of the Quantified Self in general, and of DNA analysis in particular. What is safe to share, what is reasonable to share?

I’d like to flip the question around: What is ok not to share? Maybe we even have a duty to share?

Think of the medical research that could be done, and the treatments that could be found, if more of our behavioral data was openly available. If even just one major disease could be treated more effectively by discoveries made through body tracking and our shared data, would that not be worth it?

It’s a question we can’t answer, but I urge you to think about it. Maybe it’ll make you want to track and share some more.

Until then we encourage you all – both users and producers of Quantified Self services – to pay privacy implications the attention they deserve. So that at some point we can stop worrying and start building stuff that helps us be more ourselves.

The Quantified Self in health and lifestyle

If there’s one area where we can really see body tracking taking off, it’s medical and lifestyle. There’s hardly a week where no new service or app is launched, or a new self-tracking hardware shipped.

This is the second article in our series on the Quantified Self.

If there’s one area where we can really see tracking taking off, it’s medical and lifestyle. We deliberately combine both as the boundaries are increasingly blurry: Whereas medical emcompasses all things health-related, by lifestyle we mean to include the kind of active lifestyle that the fitness & sports industries portrait.

There’s hardly a week where no new service or app is launched, or a new self-tracking hardware shipped.

That’s not surprising in itself. After all, in the medical sphere tracking body data has always been a tool of the trade. Tell a diabetic about your fascination with body tracking and they’ll give you an odd look, after all they’ve been doing it for years. What is fascinating, though, is how QS applications have been moving towards the mainstream. Step by step, these services have become easier to use, slicker, better designed. In other words, they’ve started to make it fun to track your body.

Feedback loops, self optimization and peer pressure

The basic idea of the Quantified Self in health and fitness is obvious: Only if you know how you’ve been doing, you can really improve yourself. In other words, you need to look at data over time to see your progress. So if you keep a regular record of how fast and how long you run, you will eventually get to a point where you see the curve going up or down – in other words, where you become fitter or lazy, you see regularities and irregularities, and potentially you see patterns. For example, you might discover that you perform much better in the morning than in the evening, and could plan your workouts accordingly.

We know that feedback loops work: This principle has similarly been used in most nutritional treatments for a long time, from the blood sugar testers diabetics use to the point system of the Weight Watchers.

Tracking yourself is only part of the deal. It becomes much more magic once you share your data, either with your trusted peers or with the world. This opens up a whole treasure trove of new possibilities: Aggregated, anonymous data might be used for research, or to show fancy statistics like average fitness per city. More targeted, private sharing with your friends can provide encouragement to stick to your ambitious routine even when it’s cold and rainy outside. Never underestimate the power of peer pressure!

The autonomous patient

There is a mega trend at work here that makes all of this particularly relevant to the medical sector: Patients are becoming more autonomous, driven by three factors.

One, thanks to Google patients have more access to medical information than ever before.

Two, spending cuts on government programs for social and health care increase the pressure for their citizens to take better care of their own health.

Three, we now have the technology to do this. Sensors are becoming so cheap and ubiquitous that it’s simple and cheap to track your fitness, making it more attractive for those who are motivated to improve themselves.

Today, we have more control over our body’s fitness than ever before, and now we have the data to prove it. The Quantified Self is a manifestation of the empowered user/citizen/patient.

And let’s not forget: From an economic standpoint, the global health and fitness market is gigantic. Numbers differ vastly depending on which aspect you look at, but in many countries we’re talking billions, and the boundaries between medical and fitness/lifestyle are blurry.

Calories, scales and workouts

The pure size of the market surely is one of the reasons why so many different players are gathering here, from sportswear producers (Nike+) to medical suppliers and gadget producers (Jawbone) to telcos (T Mobile, AT&T) and web startups (Massive Health, Runkeeper).

The mere range of devices and services already out there is mind boggling. From scales to food tracking apps to all kinds of fitness & workout trackers to sleep trackers and combinations of any of these, there’s hardly any activity that’s untrackable. And not all these services are geeky and require carrying around odd hardware. For Nintendo’s popular video game console, the Wii, you can get the Wii Fit game that wraps your home workout into a game. The Jawbone Up comes in the shape of a quite neat wrist band.

However, not all body trackers are created equal. There are tremendous differences, and let the rapidly growing number of tools not deceive you. This is an emerging field, and it’ll keep exploding for awhile before consolidation kicks in and we’ll truly be able separate the wheat from the chaff.

How are the apps different?

Some of the axes of differentiation are becoming clear:

  • Stand-alone apps vs integrated systems consisting of hardware and networked software
  • Explicit vs implicit trackers: Do you have to input data by hand or is it collected automatically?
  • More open vs more closed systems: Can you move your data in and out of the service, or hook it up to other services?

Runkeeper: One service to rule them all

It’s too early to tell, but if we should wager on one killer service that will come out on top of the market, it would be Runkeeper. What started as a relatively simple Android app to track your running and share it online has since grown into a massive platform that aggregates all kinds of data, and provides an API for third party developers to build apps on top of that platform.

Runkeeper confidently calls this powerful database their Health Graph, and currently it allows access to a wide range of data points like sleep, strength training, diabetes, nutrition, overall health and activities.

The Up-and-coming

There are a few other hot candidates for the upcoming months.

Massive Health is the brainchild of interaction designer and former Creative Lead for Firefox Aza Raskin. With a designer as co-founder it’s no wonder that the company brings a design twist to health. Their first of a series of apps is The Eatery, a nutrition analysis tool: snap photo of meal, learn about health implications. It’s far from perfect, but if it keeps evolving it will provide an easy, fun way of learning more about the way you eat, and of making better-informed nutritional choices – a feedback loop.

With their new Up, Jawbone (otherwise better known for bluetooth headsets) explores new territory. Their stylish wristband is equipped with motion sensors that track movement and sleep. The wristband also serves as an activity reminder that vibrates if you sit still for too long in front of your computer. The data is analyzed online, and the app shares feedback of all sorts through an app on your iPhone. Additionally, the app also allows you to snap photos of your meals, and the Up will run image analysis to give you better information about your meals. Add some social gaming group dynamics, and you have what promises to be a pretty well-rounded offer – and potentially a way out of the dilemma of having to carry around a whole set of smaller gadgets to capture different kinds of data.

What’s next?

For a while, we’re going to keep seeing the medical and fitness sector advancing the Quantified Self. They’re the obvious candidates to be trailblazers and innovators: They have the financial backing of a big, only partially tapped market. They offer strong incentives, namely self-improvement, health and fitness. And they come equipped with the right skills, sensors, and experience in tracking body data. Eventually, self-tracking will become ever easier and thereby more mainstream. Nike+, Runkeeper and the Up give us a glimpse of the things to come.

Until then we can only encourage you to experiment. Get a scale, an app, or some sensors and start tracking away. It’s good fun and you’ll learn something about yourself.
