Your next diet, fitness, & sleep coach will probably be a wearable gadget like this one

Lark, the startup that makes those nifty sleep-tracking, insomnia-curing wristbands, has just taken its product a step further. Today, the company launched a new wristband that brings diet and exercise into the biometic fold.

Called Larklife, the new product combines hardware and software to track personal health factors such as how many steps you take, how many calories you burn, and how soundly you sleep. That data is gathered automatically and passively by Larklife’s dual wristband hardware: one band for sleeping, the other for waking hours.

Food tracking has been built into a one-click process; just tap a button on your wristband, and you can enter your nutritional info on the free Larklife iPhone app at your leisure.

The system then analyzes the data and makes personalized recommendations for your health and wellness based on the input of a team of scientists and sleep, diet, and fitness experts. For example, if your Larklife nighttime wristband knows you didn’t get much real rest last night, the Larklife iPhone app will remind you to eat an extra healthy, fuel-packed breakfast to keep your energy level and concentration up.

The wristbands themselves were designed by Ammuniton, the design shop that previously designed the Beats line of headphones bearing Dr. Dre’s moniker.

Here’s what the system looks like:

In addition to providing instant recommendations for better health via iOS notifications, Larklife pulls in gamification elements to incentivize users by celebrating their accomplishments.

In some ways, it’s a bit like Nike’s FuelBand or the popular Fitbit lineup. But adding the sleep component is Lark’s secret sauce.

The original Lark product was a simple wristband that tracked your sleep, woke you with a gentle buzz from a small vibrating component, and proceeded to make recommendations to help you sleep better.

Larklife is available for $149; the company’s sleep-only coach sells for $99.

Lark was founded in 2010 by Julia Hu; the startup is based in Mountain View, Calif., and has taken a grand total of $80,000 in funding to date — not a huge amount for any startup, let alone a hardware venture, which makes the young company’s progress all the more impressive.
