You will be prompted to pair your device during setup, or from the Device Management page in settings. Once your Polar device is paired, you must power OFF before your first swim workout.

The goggle side prompt is an important part of the Phlex system as we use that information to process your workouts correctly.

Once you have paired your device with the Phlex Swim app, you are ready to go! Please refer to our goggle fit and first workout instructions to ensure you follow each step correctly.

Properly wearing the Polar Verity Sense is critical to a great Phlex experience. By exploring the many options for goggle clips, device orientation and more, you'll be more comfortable with the device.
‍

There are 3 main ways to wear the Polar Verity Sense that we highlight in our How to wear the device video.


1) Phlex White Clip: A comfortable fit for competitive goggles and common brand favorites like the Arena Cobra or MAGIC5 goggles.

2) Polar Black Clip: Great fit for most goggles, low profile. Best tested with Swedish goggles, vanquishers and more.

3) Under the cap with no clip: For swimmers who have a difficult time finding a comfortable fit, we eventually recommend slipping the device under their cap with the silver button facing up. This method has a high risk of bad data from wrong placement.

Device orientation is critical to recording good swim data:

1) The Polar device should always have the green heart rate sensor lights touching your skin.
2) The silver button should always be facing up.
3) Device worn on the same goggle side as chosen during device setup.

If you fail to wear the tracker in it's correct orientation, you will have issues viewing your workout correctly.

Turn the device ON by pressing and holding the silver button till you see the device light up. Once you see green lights, the device is recording your workout.

Important: Never go from syncing the device directly into a workout. You must power the device OFF after sync, then back ON to start the workout.

Swimming with Phlex is simple. Just wear the device while you train and we will do the rest. If you are experiencing any issues with data after the workout not looking correct, please reference our Perfect Data Guide.

When you are ready to sync, simply open the Phlex Swim App and turn ON your Polar Verity Sense device. This will recognize your device and offer to sync your recent workouts.

Due to the large amount of motion data needed to process from your swim, sync can take a couple of minutes. We recommend users be patient and background the mobile app during long syncs.

Note: 1 Hour of swimming data = 3-4 minutes of sync time

When you sync a workout, we check to make sure your profile has a valid membership. If you see a subscription popup, this means you don't have a subscription for your account.

Once you purchase a subscription or have one assigned to you, your workouts will process as usual.
