Quick answer, verified October 20, 2026
The Polar Loop costs $199.90 (EUR 179.90, GBP 149.50) and has no subscription; every feature and the Polar Flow app are free from day one. It launched on September 3, 2025, with shipping from September 10.
- Battery: up to 8 days, with 4 weeks of onboard data storage.
- Sensor: Polar Precision Prime optical heart rate, plus activity, sleep and recovery tracking.
- Workouts: start sessions in Polar Flow or rely on automatic training detection.
- Design: textile band in Greige Sand, Night Black or Brown Copper; extra bands cost $29.90.
- Reviews: TechRadar found heart rate tracking good but called the software a let down.
The short verdict
Polar Loop is the most training focused of the subscription free screenless bands. It inherits Polar’s long history in heart rate measurement and its sports science metrics, and it costs about the same as one year of the cheapest Whoop membership, once. The tradeoff is software polish: TechRadar liked its heart rate tracking but called the software a let down.

What it tracks
Polar Loop records heart rate, activity, sleep, recovery and training load in the background and syncs to Polar Flow, where readiness and recovery insights live. Tom’s Guide lists its sensors as heart rate, skin temperature and an accelerometer; unlike the Fitbit Air and Amazfit Helio Strap, it does not list SpO2.

Privacy and the no subscription promise
Polar positions Loop as privacy first: the company says data stays yours, can be exported or deleted, is never sold to third parties, and is erased if you close your account. That is a clear contrast with membership based trackers.
How it compares
- Fitbit Air: $99.99, core features free, optional Premium at $9.99 a month, 7 day battery.
- Amazfit Helio Strap: $99, no subscription, 10 day battery.
- Garmin CIRQA: $199.99, optional Connect+, up to 10 days.
- Luna Band: about $175, no subscription.
- Whoop 5.0: hardware included with a membership of $199 to $359 a year.
Who should buy it
Buy the Polar Loop if you already train with Polar gear or want Polar’s heart rate and training load metrics without a monthly fee. Choose a cheaper band if you mainly want sleep and step tracking, and choose Garmin CIRQA if you live in Garmin Connect.
