Inventions of the Young and Geeky
Julia Hu, the founder of Lark Technologies, tracks her own sleep and activity with a product she created, a wristband called the LarkLife. Lark makes a variety of wrist devices that track the wearer’s exercise, diet, and sleep patterns. The devices, which sell for $99 to $159 each, offer personalized coaching via an iPhone app.
Products sync with wearers' smartphones to provide real-time data by digesting it into simple tips--similar to what one might find in a health or lifestyle magazine. But imagine the magazine is written specifically for you--your sleep patterns, your diet, for the past seven days.
