Polar Loop Review 2025 – Does It Still Compete With WHOOP and Other Wearables?
The Legacy of Polar Loop
Polar was one of the early innovators in the fitness tracker space. The Polar Loop, first launched years ago, was designed to measure daily activity, heart rate (with a chest strap), and basic sleep data.
But in 2025, the wearable landscape is dominated by WHOOP, Oura, Apple Watch, Garmin, and Fitbit. So the question is: does Polar Loop still matter today, and how does it compare to modern competitors?
Polar Loop – What It Was Designed For
- Daily Activity Tracking – steps, calories, inactivity alerts.
- Heart Rate Monitoring – via chest strap (not built-in wrist sensor).
- Sleep Tracking – very basic compared to modern devices.
- Water Resistance – safe for swimming and daily wear.
- Battery Life – 4–6 days, depending on use.
At the time, Polar Loop was considered innovative. But by 2025, its features are extremely limited compared to newer wearables.

Final Verdict – Polar Loop in 2025
Polar Loop was a pioneer, but in 2025, it’s more of a legacy device than a competitive option. If you want advanced recovery, sleep, and performance insights, WHOOP or Oura are much stronger. If you want GPS and training depth, Garmin is the better choice.
Polar itself now focuses on its newer Ignite, Vantage, and Grit series, which are more relevant to today’s users.
