Nearly a year after Fibit first announced the Alta Fitness tracker, it’s unveiling a new model with heart rate monitoring built-in. It’s nearly identical to the previous generation in looks until you flip it over. That’s where you’ll find all of the new sensors that will monitor your heart rate throughout the day and make suggestions about how to burn the most calories. Fitbit is expecting around seven days of use on a full charge which is a smaller improvement over the previous generation. The new heart rate-friendly model will retail for $150 in standard finishes or $180 for metal finishes like Rose Gold when it hits shelves next month.

Today’s Fitbit announcement also brings a big upgrade to the Blaze and Charge 2. A software update via mobile will soon enable Sleep Stage tracking that notes the quality and duration of your slumber. This is something that Apple Watch continues to struggle with, so today’s move puts Fitbit in a stronger position for those interested in sleep data.

“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, co-founder and CEO 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.”
