FAQ
Can I use Polar Loop together with other Polar products, such as a sports watch?
Polar Loop is designed for comfortable 24/7 wear, making it a great companion for multi-device users. It fills in the gaps during the day when wearing a sports watch may not be ideal, so you don’t miss out on activity, sleep, or calorie tracking.
It is not recommended to wear and use Polar Loop and another Polar device at the same time. When Polar Flow receives data from more than one device, it compares the timestamps and keeps the highest recorded values. To ensure accuracy, make sure both devices are synced regularly.
If you track the same training session with multiple devices, you may see duplicate training files and duplicated training load data. In that case, we suggest deleting the extra file to avoid confusion.
Is Polar Loop suitable for swimming?
Yes — Polar Loop is water-resistant up to 30 meters (WR30), meaning it is suitable or bathing and swimming. It will track your heart rate and calorie burn, but it does not provide specific swimming metrics such as stroke count or distance.
For the most accurate heart rate data in water, wear the device snugly on your wrist—tighter than you would for other activities.

What’s the difference between Polar Loop and Polar 360?
Polar Loop and Polar 360 (a B2B product) share most of the same sensors and core features. The differences are mainly in design and battery: Loop has a more premium finish and slightly extended battery life (up to ~8 days under typical usage).
Learn more about Polar Loop and Polar 360:
- Polar Loop User Manual (https://support.polar.com/en/manual/#polar-loop)
- Polar 360 Product Page (https://www.polar.com/en/business/polar-360)
Can Polar Loop be used with 3rd party services or products?
Polar Loop supports one Bluetooth Low Energy (BLE) connection, which is reserved for syncing with the Polar Flow app. This means it cannot be used as a heart rate sensor for other devices, nor does it support broadcasting to external devices or group solutions.
However, you can still share your Polar Loop data with selected third-party services such as Google Health, Apple Health, Strava and TrainingPeaks through your Polar Flow account.

- Connecting Polar Flow with Apple Health (https://support.polar.com/en/support/connecting_polar_flow_with_apple_health)
- Connecting Polar Flow with Google Health (https://support.polar.com/en/flow-app-health-connect)
Does Polar Loop have GPS tracking?
Polar Loop does not have built-in GPS. However, when training recording is started from the Polar Flow app using an outdoor sport profile and mobile is selected as recording device, GPS of the mobile can be used to record route, speed, pace, and distance.
Read more about recording training sessions with the Flow app:
- Manual Training Recording (https://support.polar.com/en/polar-loop-manual-training-recording#Polar_Loop&polar-loop)
What is the difference between the Precision Prime and Elixir sensor platforms?
Precision Prime is Polar’s most cost- and weight-efficient optical sensor platform, making it an ideal choice for a 24/7 health tracker like Polar Loop. Although it uses different hardware than our larger watches with the Elixir sensor platform, Loop relies on the same advanced heart-rate algorithms as our premium devices.
Success! ##
