Product Description

Heart Health.

There’s more to your heart health than beats per minute. Our advanced bioimpedance sensors are able to track your heart rate and use that information to help you take care of the most important organ in your body.

Smart Coach.

Because the UP3™ band captures so much information, Smart Coach is even smarter. It uses everything it learns about your activity, sleep, food and heart rate, so it can give you deeper insight and more personalized tips to reach your goals faster.

Advanced Sleep Tracking

UP3™ uses advanced sensors to track your sleep stages – REM, Light and Deep. Smart Coach is then able to give you suggestions to maximize your sleep and improve the quality of your days.

Advanced Activity

The more you do, the smarter UP3™ becomes, by learning to recognize and automatically log all your activities from running to a pickup game of basketball. Smart enough to know what you’re doing, UP3™ gives you a detailed picture of your calorie burn.

Food & Drink Logging

Improve the quality of your diet and achieve your ideal weight by logging your meals in the UP® App. Track food, drinks, calories and nutrients in the app by scanning a barcode or logging a meal at your favorite restaurant. There’s even a Food Score to help you know how healthy your food choices are on a simple scale of 1-10.


Keep your eyes on the prize by setting personalized goals: from steps per day and hours slept, to target weight. The UP® system helps you reach your goals with activity recommendations, helpful tips, and encouraging reminders.

Team UP

Connects you with friends and family so you can reach your goals together or see how you measure up on the team leaderboards.

Never go it alone. UP® allows you to connect with friends and family, so you can reach your goals together. When UP® community members have three or more friends on their team, they move at least 16 extra kilometres a month. That’s a lot of calories burned.

Mood Tracking

Track your mood throughout the day and the Smart Coach will provide insights on sleep and activity to help you improve your mood.

Water resistance

Splash‐proof water‐resistant. Cannot be submerged in water.


Always connected via Bluetooth Smart so you never need to worry about uploading your data.
