Transcript for First Look at New Fitbit: How Does Wristband Compare?
Now our exclusive sneak peek at the fitbit that tracks everything from the calories you burn and the steps you take to the quality of your sleep. ABC's Becky Worley tried it out. Reporter: If you're a die-hard of fitbits you know the tech gadgets track your step, distance and calories so when brookstone leaked a picture of new fitbits that hadn't been announced by accident the internet went crazy. Everyone wanting the scoop. The company that makes fitbits decided to give "Gma" an all-access first look at what's really coming. First a new band that does the basics but adds heartrate data in realtime. But with actual heartrate monitoring you can get calorie burn for cycling and weight lifting you couldn't get calorie burn before. Reporter: It cops out in early 2015 along with the surge. Where things get interesting it does all of the tracking and adds in the heart rate monitoring and then it connects with your phone so that means music controls and text and phone alerts. Ah, I love you. So cute. Reporter: Why is this a big deal? Looming in the near future a battle for your wrist. There's apple's extension of your phone with a little fitness tracking sprinkled in, the Intel powered basis peak which adds a fashionable strap and some really powerful tracking functions for sleep. Everyone is trying to distinguish themselves and then there's this. It's called the Pavlock. A real product in development. The premise? Experience the electric shock that keeps you on track. Reporter: You set a goal in its app. If you don't reach that goal let's say 10,000 steps for the day by 4:30 P.M., this is what happens. Ah. Yeah, it shocks you. 255 volts of motivation. So as you contemplate the next gadget you'll strap to your wrist, I got to get running to avoid another jolt. For "Good morning America," Becky Worley, ABC news, San Francisco. Wow. That is motivation. It shocks you. Incredible.
