Auto Exercise Recognition

Take the work out of workout tracking.


Isn’t it great when things happen automatically?
Porch lights. Coffee makers. Thermostats.
And now, recording workouts.

That’s the power of SmartTrack.

Get credit for your effort.

SmartTrack automatically recognizes and records your workouts and captures all your stats: like how long you were active, calories burned and heart rate zones.

With SmartTrack keeping track, you realize that every little workout counts—from a lunchtime stroll to your daily bike commute. Suddenly, hitting your exercise goals feels like a walk in the park.

Tracks this. And that. Oh, and that too.

SmartTrack recognizes activities with continuous movement or high movement.

Walking (includes hikes)
Aerobic Workout (continuous, high movement activities like dance or kickboxing)
Outdoor Bike
Sports (continuous, high movement activities like tennis, basketball, soccer)
Swimming (only on
Fitbit Flex 2™)

Inside your tracker, SmartTrack is continuously running calculations to detect when you’ve been moving for 15 minutes or more.

When you’re done, a workout summary automatically gets logged to the Fitbit app.
