Daily Activity and Exercise Tracking

Fitbit Inspire 3 tracks essential daily fitness information, including:

• Steps taken

• Distance travelled

• Calories burned

• Active Zone Minutes

• Exercise duration

• Heart-rate zones

Multiple exercise modes let you track activities such as walking, running, cycling, weights and yoga. SmartTrack can automatically recognise supported exercises and record them in the companion app after your workout.

Connected GPS

Connect the Fitbit Inspire 3 to your compatible smartphone’s GPS to view pace and distance during outdoor walks, runs, hikes and bike rides.

The tracker does not have standalone built-in GPS, so your phone must be nearby when using connected GPS.

Stress Management Features

The daily Stress Management Score helps you understand how your body may be responding to stress.

Guided breathing sessions, mood reflections and mindfulness tools can help you create moments of calm throughout your day. Some detailed insights and mindfulness content may require a Premium membership.

Health and Wellness Insights

The Fitbit Inspire 3 includes sensors that support wellness information such as:

• Resting heart rate

• Heart-rate variability

• Skin-temperature variation

• Blood-oxygen trends

• High and low heart-rate notifications

• Irregular heart-rhythm notifications where available

Availability may vary by country, device settings and account eligibility. These wellness features are not intended to diagnose, prevent or treat a medical condition and should not replace professional medical advice.

Bright AMOLED Colour Display

The colour AMOLED touchscreen makes daily statistics, workout information and notifications easy to view.

An always-on display mode is available for users who want information visible without waking the screen. Using the always-on display and certain health features may reduce battery life.

Up to 10 Days of Battery Life

A full charge can provide up to 10 days of battery life, reducing the need for frequent charging.

Actual battery performance varies according to display settings, feature usage, notifications and other factors. Fitbit states that a complete charge takes approximately two hours.

Water Resistant to 50 Metres

Fitbit Inspire 3 is water resistant to 50 metres and is suitable for swimming in shallow water, rain and sweaty workouts.

It is not waterproof and should not be used for high-speed water sports, diving or activities involving high-temperature water. Water resistance can decrease over time due to wear, impact or damage.

Smart Notifications

Stay connected by viewing supported call, text and smartphone app notifications directly on your wrist when your compatible phone is nearby.

The Find My Phone feature can also help locate a connected phone within range.

Weighing approximately 17.69 grams, the Fitbit Inspire 3 has a slim profile designed for comfortable all-day and overnight use.
