--- title: "Polar Loop review" description: "Polar Loop review: a screenless, subscription-free band with 8-day battery, WR30 water rating and Polar Flow app. Specs, owner feedback and who it suits." canonical: https://vettedten.com/us/tech/fitness-trackers/polar-loop/ language: en-US updated: 2026-11-11 score: 8.4 --- # Polar Loop review > **Our verdict:** The Polar Loop ranks 9th of the 10 fitness trackers we compare, with 8.4 out of 10. No. 9 of 10 in our [fitness trackers ranking](https://vettedten.com/us/tech/fitness-trackers/) · Updated November 2026 · [How we rank](https://vettedten.com/how-we-rank/) **8.4 out of 10** The Polar Loop is a screenless wrist band that tracks heart rate, sleep and recovery all day and reads out in the free Polar Flow app. It suits people who want training data without a display or a subscription. Why it's here: - Subscription-free, with the Polar Flow app free to use - Up to 8 days of battery and about four weeks of stored data - Records workouts without the phone, with heart rate only - Rated WR30, so fine for pool swimming Keep in mind: - No screen, so stats and alerts are read in the app rather than on the wrist - No GPS of its own, and a high price for a screenless band - Replacement wristbands are sold separately [Check price on Amazon](https://www.amazon.com/dp/B0FM8JGSTP) ## Why the Polar Loop scores 8.4 - How happy owners are: 8th of 10 - How many rated it: 8th of 10 - How new it is: 3rd of 10 ### Level with the Amazfit Helio Strap The Amazfit Helio Strap and the Polar Loop score the same, so either is a safe pick. The Amazfit Helio Strap goes first because it leaves owners a little happier. ## About the Polar Loop The Loop has no screen and no buttons. All data goes to the Polar Flow app over Bluetooth, and nothing is shown on the wrist. The case is stainless steel, measures 1.1 in wide by 1.7 in high and 0.4 in thick, and the band weighs about 1 oz with its wristband. Polar rates it WR30, so it can go in the pool, and it records heart rate and calories in water but not stroke count or distance. It carries Polar's Precision Prime optical heart-rate sensor and an accelerometer. It records heart rate around the clock, plus nightly HRV and sleep stages with a daily sleep score. Polar's Nightly Recharge, SleepWise and Training Load Pro are included. There is no GPS in the band. For a route, you start the session in the Flow app and the phone's GPS does the work, while the band supplies heart rate. Battery life is up to 8 days, and the band stores about four weeks of data between syncs. It charges with the included Polar Charge 2.0 cable, which ends in USB-C. In the box you get the Loop, a SoftWeave band with buckle, and the cable. Other bands (silicone, leather and a sport armband) are sold separately. The Loop cannot act as a heart-rate sensor for other devices, and Polar advises against wearing it alongside another Polar device. Data can pass from Flow to Strava, TrainingPeaks, Apple Health and Google Health. ### Key specs - Battery: 170 mAh, up to 8 days per charge - Water resistance: WR30 - Heart-rate sensor: Polar Precision Prime optical (OHR Gen 3.5) - GPS: None (uses phone GPS via Polar Flow) - Size: 1.1 in W x 1.7 in H x 0.4 in thick - Weight: About 1 oz with wristband, 0.7 oz without - Case: Stainless steel - Onboard memory: About 4 weeks of data - Subscription: None - Guarantee: 2 years, as listed on Polar's US page ## What owners report about the Polar Loop Owner feedback on this exact model is thin: the only account we found came from one forum comment, so treat it as a single report, not a pattern. That owner found sleep times and HRV close to what their Suunto and Apple Watch Ultra showed, and heart rate worked well for them. They called it good value for a band with no subscription. They found automatic workout detection very basic, the Polar Flow app hard to navigate and more like a data analyst's tool, and were surprised the band has no SpO2 or body temperature sensor. ## Who the Polar Loop suits The Loop fits someone who wants heart rate, sleep and recovery data without a screen on the wrist and without paying monthly. It also suits existing Polar users who want a light band for sleeping and everyday wear. It works best if you start your workouts yourself in the app, because the independent review we read found automatic workout detection was the weak point: sessions were missed, split or cut off late, and they could not be edited afterward. Look elsewhere if you want the time, notifications or stats on your wrist: the Garmin vívosmart 5 or Fitbit Charge 6 have screens. If you want a screenless strap, the Amazfit Helio Strap or Garmin Cirqa are the other options in this guide. Anyone who needs built-in GPS, a wake-up alarm or heart rate sent to a bike computer or gym machine will also need a different device. ## Questions about the Polar Loop ### Is the Polar Loop a good Whoop alternative? Partly. It has no subscription and shows more detailed training data, but DC Rainmaker found Whoop far better at detecting and editing workouts, and easier to understand in its app. ### What app does the Polar Loop use? The free Polar Flow app. Everything is read there, since the band has no screen. The same reviewer said Polar has acknowledged the app is not very good and planned a redesign. ### Does the Polar Loop work with Strava and Apple Health? Yes, through Polar Flow. Polar lists Strava, TrainingPeaks, Apple Health and Google Health as places your data can be shared. ### Can the Polar Loop broadcast heart rate to other devices? No. Polar says it has one Bluetooth connection, reserved for the Polar Flow app, so it cannot act as a heart-rate sensor for other devices. ### Does the Polar Loop have an alarm? No. It has no screen, buttons or notifications, and DC Rainmaker confirmed it has no wake-up alarm, so you need your phone or another device. ### Can you swim with the Polar Loop? Yes. It is rated WR30 for bathing and swimming. It records heart rate and calories in water but not stroke count or distance. ## All 10 fitness trackers, compared | No. | Product | Score | Badge | | ---: | --- | ---: | --- | | 1 | [Garmin vívoactive 6](https://vettedten.com/us/tech/fitness-trackers/garmin-vivoactive-6/) | 9.0 | Best Choice | | 2 | [Amazfit Active 2](https://vettedten.com/us/tech/fitness-trackers/amazfit-active-2/) | 8.8 | Value for Money | | 3 | [Fitbit Inspire 3](https://vettedten.com/us/tech/fitness-trackers/fitbit-inspire-3/) | 8.6 | | | 4 | [Samsung Galaxy Fit3](https://vettedten.com/us/tech/fitness-trackers/samsung-galaxy-fit3/) | 8.6 | Best Budget | | 5 | [Garmin vívosmart 5](https://vettedten.com/us/tech/fitness-trackers/garmin-vivosmart-5/) | 8.5 | | | 6 | [Fitbit Charge 6](https://vettedten.com/us/tech/fitness-trackers/fitbit-charge-6/) | 8.5 | | | 7 | [Google Fitbit Air](https://vettedten.com/us/tech/fitness-trackers/google-fitbit-air/) | 8.4 | | | 8 | [Amazfit Helio Strap](https://vettedten.com/us/tech/fitness-trackers/amazfit-helio-strap/) | 8.4 | | | 9 | **Polar Loop** (this review) | 8.4 | | | 10 | [Garmin Cirqa](https://vettedten.com/us/tech/fitness-trackers/garmin-cirqa-smart-band/) | 8.4 | | ## How we score it Every score here comes from our ranking model; no editor sets the order. We haven't read the review sites for this guide yet, so for now it is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 15 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in November 2026.
