How do I track my swimming pace and distance?

Your Fitbit device automatically tracks the duration of your swim and the number of pool lengths you complete. To track your pace and distance, enter the pool length in meters or yards into the Fitbit app or on your watch before starting your swim. Keep in mind the pool length you enter remains the default length until you change it. If you swim in the same pool often, you don’t need to input the length each time.

Choose a section below to enter the pool length into the Fitbit app.

  • Fitbit app
    1. From the Fitbit app dashboard, tap or click the Account icon (User-added image).
    2. Scroll down to Settings and tap or click Advanced Settings.
    3. Tap or click Swimming Settings
    4. Enter the pool length and unit of measurement (meters or yards).
  • Fitbit watch
    1. On your watch, open the Exercise app (User-added image) > Swim. 
    2. Tap the gear icon (User-added image) in the top left.
    3. Find the Pool Length setting and enter your pool length.

Which strokes can I use to swim?

While you can choose to swim using any of the four most common strokes (freestyle, backstroke, breaststroke, and butterfly), we recommend swimming freestyle for the best results.

How do I track my swims with Flex 2?

The SmartTrack feature on your Flex 2 recognizes and records swims that are at least 10 minutes long. Swim detection is turned off by default; follow the instructions below to turn it on.

    2. Under Goals, tap or click Exercise.

    4. If you want to change the minimum duration that's automatically recorded, tap or click Swim Longer Than and choose a time.
  • dashboard
    1. Log into your dashboard and click the gear icon in the top right corner.
    2. Click Settings > Devices. If you have more than one device, choose Flex 2.
    3. Find Swimming and choose the minimum duration.

How do I track my swims with Ionic and Versa?

Track swims on Ionic and Versa with the Exercise app (User-added image). Note that heart rate detection is turned off while swimming. For more information about tracking exercises, see How do I use exercise apps and modes on my Fitbit device?

Do I have to be a good swimmer to track my swims with my Fitbit device?

Your device records your swims even if you’re a novice swimmer, meaning you can swim about 6 to 12 lengths of the pool without stopping to rest. If you’re unable to swim this distance, you may notice inconsistencies in your swim data including some lengths not counted. As your swimming ability improves, you’ll likely notice fewer inconsistencies in your data.

Where can I see my swim data?

On your Fitbit app dashboard, tap the Exercise tile to see your exercise history. (On, go to your activity log.) Tap or click the most recent swim log to view additional stats including the impact the exercise had on your day.

On your watch, you’ll see a summary of your swim when you end the workout.

Why do I see a length count after an open water swim?

Your device tries to identify lengths each time you swim, so you may still see an estimated number of lengths after your open water swim.

Why is my swim data incorrect?

In addition to completing only a handful of laps or stopping to rest often, inconsistencies in your swim data may be caused by any of the following:

  • Stopping to rest midway across the pool
  • Resting for longer than 60 seconds after completing a pool length
  • Changing stroke type midway across the pool
  • Swimming with a kickboard or not using your hands
  • Swimming less than the minimum duration set to be auto-recognized
  • The units for the pool length setting don't match the units you use for your Fitbit settings. For example if you measure length in feet and inches, and specify a pool length in meters. For more information, see How do I update my Fitbit settings?

Can I swim in deep water with my tracker?

Your tracker is water-resistant up to 50 meters.

Does swimming count toward my step goal?

While you don’t earn steps for swimming, the exercise counts toward your active minutes and calories burned goals. By default, your device’s primary goal will be steps taken, but you can choose a different goal. For more information, see How do I track my fitness goals with Fitbit?

Can I add or delete a swim log?

You can delete a recent swim log or manually enter the exercise if you forgot to wear your tracker. For step-by-step instructions, see How do I manually log an activity or exercise?
