Fitbit Ionic: Fitness and Health Features. You'll get everything you'd expect from a Fitbit, including tracking of Steps, Distance, Calories burned, Floors Climbed and Active Minutes, as well as automatic Sleep and Activity Tracking.

Musician and internet star Marc Rebillet taps an upbeat tune on his piano and grooves to the music in his living room. Motivational speaker and author Leah V finds joy in trying new activities, like taking to the beach and surfing for the first time. Nor Diana, a pro wrestler, pushes her limits in the ring.

Fitbit Ionic is the watch designed for your life. Find the guidance to reach your goals with dynamic workouts, built-in GPS, continuous heart-rate tracking, and more. Ionic: adidas edition also includes a unique adidas coaching experience, a signature band, and an exclusive clock face.

Founded in 2007 by James Park and Eric Friedman, Fitbit devices were the first in the market to completely change how we look at personal fitness tracking, and they continue to make major developments. Worn like a smartwatch, right on a person's wrist, the modern Fitbit makes it easy to track fitness goals.

Target Markets: Currently, Fitbit targets individuals 30+ who need to find the motivation to be active, those who are overweight, and even those who are already active but want to monitor what they do and how much they accomplish while working out.

Fitbit Ionic has a better-than-most-smartwatches four-day battery life, while still having always-on heart rate and a comfy fit. It has features galore: waterproofing, GPS and on-wrist mobile payments, plus new watch faces and a growing app store.

It found that people who wore a Fitbit kept up their physical activity a bit better than a control group without them - but after a year, it wasn't enough to produce changes in weight or blood pressure.

Fitbit devices have been used in 900+ published studies, more than any other wearable, and is the most commonly used tracker in biomedical research. Fitbit devices are registered in clinical trial studies 10x more often than any other wearable brand and are used in 95 percent of NIH-funded research.
