Fitbit Alta HR™ Heart Rate + Fitness Wristband

Fitbit Introduces Alta HR, our Slimmest Fitness Wristband with Continuous Heart Rate, to Reach your Health Goals in Style

Fitbit introduces Sleep Stages, powered by PurePulse heart rate technology, to analyze light, deep and REM sleep, and Sleep Insights to provide guidance to help improve your sleep; developed with panel of leading sleep experts from Johns Hopkins University, Stanford University and the University of Arizona

Fitbit, the leader in the connected health and fitness market, today introduced Fitbit Alta HR™ and new advances in sleep tracking, giving you actionable insights and guidance in the Fitbit® app to make more informed decisions about your health and stay motivated to reach your wellness goals in style.

• Fitbit Alta HR is our slimmest wrist-based, continuous heart rate tracking device combining the benefits of PurePulse® heart rate technology, automatic exercise recognition, sleep tracking, up to seven days battery life and smart notifications in a slim versatile design that is easily customized to fit your style. Alta HR is available today for presale, with retail availability in April.

• Sleep Stages utilizes heart rate variability to estimate the amount of time you spend in light, deep and REM sleep, as well as time awake each night to better understand your sleep quality.

• Sleep Insights uses the whole of your Fitbit data to provide personalized guidance on how to improve your sleep for better overall health.

“Alta HR and these powerful new sleep features demonstrate our continued focus on evolving our innovative technology to deliver deeper, more actionable insights to help our users improve their health,” said James Park, CEO and co-founder of Fitbit. “The miniaturization of our PurePulse heart rate technology opens up exciting opportunities for future generations of devices and new form factors. Our advances in sleep will provide millions of users around the globe accessibility to invaluable insights that previously could be obtained only through expensive lab tests.”

Heart Rate and Style in a Sleek Design

Fitbit was able to bring PurePulse, the feature requested most by Fitbit Alta™ users, to Alta HR by developing a one-of-a-kind chip that reduced the size and number of components needed, achieving a 25% slimmer design than Fitbit Charge 2™. The result is a stylish device that offers all-day, continuous heart rate tracking, making it easier for you to make more informed decisions about your health:

• Better measure calorie burn all day, including non-step based exercise like yoga and spinning, to help you stay on track toward your health and weight goals by tracking calories in versus burned.

• See real-time heart zones on your wrist and exercise summaries in the Fitbit app to work out at the right intensity for your health and fitness goals.

• View resting heart rate on-device and trends in the Fitbit app, and compare it to your activity to see how consistent exercise can improve your heart health over time. A decrease in resting heart rate is a key indicator of cardiovascular health; changes up or down may indicate illness or other issues.

Smart, Insightful, Automatic Sleep Tracking to Help You Sleep Better

Fitbit is also introducing two dynamic, new sleep tools – Sleep Stages and Sleep Insights – that provide deeper insight into your sleep quality and guidance on how to improve, building on its popular sleep features that have empowered millions of people to track their sleep since 2012. Along with diet and exercise, sleep is a key factor in overall health, but most people have very little insight into it. Good sleep plays a critical role in your health and overall wellbeing, from protecting against cardiovascular disease, diabetes and obesity, to boosting neurocognitive functions, mental health and longevity.

Sleep Stages, powered by PurePulse, uses accelerometer data and heart rate variability (the moments between beats), plus Fitbit’s proven algorithms to more accurately estimate how long you spend in light, deep and REM sleep stages, as well as time awake, each night:

• Light Sleep (including sleep stages N1 and N2) occurs throughout the night and is important for memory, learning and letting your body recover from the day; for most people it is 50-60% of your night.

• Deep Sleep (sleep stage N3) promotes a healthy immune system and muscle growth and repair; for most people that’s 10-25% of your night (depending on your age).

• REM Sleep is when most dreaming occurs and is important for mental recovery and memory formation; for most people that’s 20-25% of your night. Most REM sleep comes at the end of the night, and is often the stage to be cut short when your sleep duration decreases.

• Awake periods (between 10-30 times) are a normal part of your sleep cycle each night.

Everyone’s sleep cycle is different but by better knowing your sleep quality and patterns, and realizing the impact they have on your day.
