Fitbit has launched its autumn line-up of health and wellness tools with the Inspire 3, Versa 4 and Sense 2.

These devices are thinner and said to be more comfortable, so users can wear them all day and night, and they don’t have to charge them every day.

Whether focused on improving mental health, gearing up to run a marathon, or starting a health and wellness routine, there is a range of devices that provide information about the wearer’s body that otherwise wouldn’t be top of mind, such as resting heart rate, oxygen saturation (SpO₂), sleep trends and body’s responses to stressors.

The Inspire 3 is said to be a fun, easy-to-use tracker that helps users stay on top of their health with ten days of battery life. It is an entry-level device with a colour display that can track important metrics.

The Versa 4 is a fitness-focused smartwatch that offers more than forty exercise modes, real-time statistics, built-in GPS and active zone minutes, plus features such as a daily readiness score to help users reach their activity goals. It has six days of battery life in a thinner and lighter design.

The Sense 2 is Fitbit’s most advanced health-focused smartwatch with more than six days of battery life that helps manage stress and track heart health with sensors that can detect signs of atrial fibrillation through an ECG app and PPG algorithm, both of which are FDA cleared and CE marked. It can also track heart rate variability, skin temperature and more, and has a body response sensor that measures CEDA (continuous electrodermal activity) for all-day stress management.

“Our newest offerings are just the start of how we can help you uncover information to improve your overall health and wellness,” said TJ Varghese, Fitbit’s director of product management. “With the Fitbit app, you can stay motivated and on track with weekly and longitudinal stats about your activity, heart health, sleep and stress. Plus you can log your hydration, menstrual health, mood, nutrition and glucose levels all in one place. Seeing all of your metrics together can help you better understand how the actions you take each day can impact your well-being and make better decisions for your daily life.”

They provide access to health features, including irregular heart rhythm notifications, which uses a photoplethysmography (PPG) sensor to assess heart rhythm for signs of atrial fibrillation (AFib) for users 22 years or older with no known history of irregular heart rhythm. This feature has both FDA clearance and CE marking, and it is compatible with a range of Fitbit’s heart-rate enabled devices.

Fitbit Premium is included with all new device purchases for six months with additions such as daily readiness score and sleep profile to dive deeper into stats and progress, and more than 1000 workout and mindfulness sessions to keep the wearer’s mind and body active.
