How the Larklife Wristband Could Turn Us All Into Quantified-Selfers

How the Larklife Wristband Could Turn Us All Into Quantified-Selfers

If you’re willing to to walk around all day wearing sensors that record your activity and compile the data into fancy reports and graphs, you must be either a pretty big geek, or a fanatical athlete training for an ultramarathon-style event, or both.

At least, that’s been the conventional wisdom. And there’s some truth in this point of view. Most of the personal fitness monitoring devices on the market today, like the Fitbit Ultra and the Nike+ Fuel Band, are too complicated, too expensive, or too specialized to appeal to the average consumer.

So you run into the usual irony: the early adopters of these gadgets—mostly active young urbanites or adherents of the quantified self movement—are the very people who need them the least, since they’re already likely to be vegan-locavore types who run, cycle, and do yoga every day.

But now a Silicon Valley startup called Lark is working to change the image of the personal fitness device—and make it into something that soccer moms in Sacramento and plumbers in Poughkeepsie can imagine using.

At the moment, Lark is known mainly for its sleep coaching technology, which pairs a wireless wristband with a customized iPhone app that records the wearer’s dozing patterns and offers tips for better sleep. In a huge coup for the startup, the Lark Pro system was selected by Apple in 2011 for distribution in Apple Stores worldwide. It’s been a big hit with insomniacs; it even got endorsed as an official product of the National Sleep Foundation.

The Larklife wristband

But this holiday season, Lark will introduce a second and far more ambitious product designed to help wearers eat better, become more active, and control stress levels (while sleeping better too).

It’s called Larklife. And while it may look like yet another electronic wristband, it’s actually something much more interesting: the first in a new wave of hybrid wearable/mobile/cloud technologies that could help average consumers take better control of their own health and well-being.

“When we found out [with Lark Pro] that we had stumbled upon some really intuitive ways to change behavior and help people sleep better, we looked around and thought about the other big problems that people had that we could help with,” says Julia Hu, Lark’s founder and CEO. “We asked tons of people what they would like, and what they told us was, ‘I want to look great, feel great, and be less stressed and more productive.’ So we took the behavior change method of helping people sleep better and applied it to the rest of your day.”

Lark announced the $149 Larklife in early October, and Hu says it will go on sale this holiday season. This week, I was the first journalist to get a close look at the device, during a visit to Lark’s office in Mountain View, CA.

It’s a stylish, bright-blue rubber wristband, reminiscent of the “Livestrong” bracelets from Lance Armstrong’s pre-doping-scandal days, but thicker. The snap-in core contains batteries, a three-axis accelerometer, and a simple row of LED lights; at night, you remove the core from the blue band and slip into a softer cloth band that’s meant to feel more pajama-like.

The whole setup was designed by Ammunition Group, the San Francisco product design firm currently winning buzz for creating the “Beats by Dr. Dre” audiophile headphones.

There’s a single button on the side of the band, which you can touch to log events like eating a meal or a snack, or to sync the device’s data to your smartphone over BTLE—a new low-power form of the Bluetooth wireless communications protocol. The motion sensors inside measure how much exercise you’re getting as you move through your day and how much you’re tossing and turning in bed at night. When you do something virtuous like eat vegetables or go for a run, the LEDs on the band reward you with a miniature light show.

But the real smarts of the Larklife system aren’t in the band at all—they’re in the associated iPhone app and the cloud-based machine learning software that powers it. Over time, the app gets to know you and your patterns, and learns when to interrupt with cheery messages and gentle suggestions—along the lines of “You haven’t been active for a while. Walk around a bit to engage your muscles and get your blood flowing again.”

It’s the same idea behind the Lark Pro sleep monitoring system, just on a larger canvas—all reflecting Lark’s unifying idea that sensors, mobile devices, and cloud services can work together to create a new kind of experience for consumers. Hu calls the Larklife app “a friendly real-time coach in your pocket” that uses emotional rewards, rather than dry clinical reports and graphs, to help users form healthier habits.

Both products have their genesis in Hu’s studies at Stanford, where she was a master’s student at the Institute of Design (better known as the “d.school”) and picked up the principles of “persuasive design” from behavior-change expert BJ Fogg.

Hu’s version of Fogg’s philosophy goes like this: Everyone begins the day with a finite fund of willpower, defined as the ability to make decisions, stay on task, and resist impulses such as the urge to check Twitter or scarf another Oreo. As you make one decision after another, your willpower fund is … Next Page »

    If you think the fuelband is complicated, you probably should not be a technology reviewer. It’s basically a laziness meter and motivates me to move more. It costs the same as the larklife and looks much better.

      I agree, neither is really complicated. However, the Larklife does a good bit more than the Fuelband, which is what ultimately prompted me to get it instead. I do like the small, sleek nature of the Fuelband, but the Larklife is actually a lot more comfortable to wear than I expected! I’m enjoying it a lot, I wish it had a watch, though! :)

    I love tech. I hate diet, exercise, and complication. I love simplicity. I’m always looking for and suggesting a better way of doing things, with less steps, and more automation. Why? I’m lazy. No really I have Narcolepsy and it does not in any way help my life to have to remember to do steps 1-5. I’m between the Lark and the Up. The main thing for me is tracking my very random sleep patterns in real time and getting that feedback so that I may possibly get better control of my sleep patterns. Totally think the Lark for that, especially since they key people behind it’s development are the Standford Sleep Specialist. 2 day battery life sucks though and its about 10 with the Up. I just don’t know. The other big difference between the Larklife and Lark Pro is in the app it’s self. I could really benefit from the extra sleep tracking features of the Pro app in the Life app. I don’t know.
