Side-by-Side Comparison
| Spec | Polar Loop (2025) | WHOOP 5.0 (Peak membership) |
|---|---|---|
| Price | $199.99 | $239.00 |
| Release Year | 2025 | 2025 |
| GPS | None — no GPS chip. The Polar Flow app can use the phone's GPS when you start an outdoor session manually | None — no GPS chip. Route and pace exist only if the phone comes with you |
| Display | None — screenless; everything is read in Polar Flow | None — screenless; the band shows nothing and every metric is app-only |
| Rated Battery Life ( days) | 8✓ | 4 |
| What the Battery Claim Assumes | Polar rates up to 8 days with continuous HR active; the band holds about four weeks of data if it goes unsynced | WHOOP claims '4+ days' from the device itself. The advertised '14+ days' is the band PLUS the wireless PowerPack — which the Peak tier includes and the cheapest One tier does not |
| Subscription Model | None. Polar states full access to every feature from day one with no monthly fee — the explicit anti-WHOOP position | Mandatory. WHOOP does not sell the hardware at any price — Peak is $239/year and the band comes with it. WHOOP states it stops collecting, uploading and analysing your data once the membership ends |
| Annual Subscription Cost ($) | 0✓ | 239 |
| Water Resistance | WR30 — Polar rates it for bathing and swimming, a weaker rating than the 5 ATM bands here | WHOOP markets the band as swim-safe; no ATM or IP figure is published in the 5.0 launch materials |
| ECG / AFib & FDA Status | No ECG hardware and no AFib detection | No ECG hardware on 5.0 — the ECG electrodes and the FDA-cleared ECG feature are exclusive to the WHOOP MG. 5.0 gets PPG-based irregular-heart-rhythm notifications |
| SpO2 Sensor | Not listed by Polar for the Loop — the sensor package is optical HR, HRV and accelerometer | Yes — blood oxygen, included on the Peak tier |
| Phone Compatibility | iOS and Android via Polar Flow | iOS and Android |
| Charger | Proprietary Polar Charge 2.0 USB-C cable (included) | Wireless PowerPack (Peak and Life tiers). The $199 One tier ships a basic wired charger and a certified pre-owned 5.0 rather than a new one |
| Data Export | Strongest in the screenless class — Polar Flow exports sessions as TCX/GPX, offers a full account data export and a documented AccessLink API | Member data download and a developer API while the membership is active; access to the archive follows the membership |
| Warranty | 24 months | 12 months |
| Colors | Black, Greige, Blue | Onyx SuperKnit (additional bands sold separately) |

Pros & Cons
Polar Loop (2025)
Pros
- +Polar's sports-science pedigree — Nightly Recharge and SleepWise — with no subscription attached
- +Two band sizes in the box, so the fit problem is solved at purchase
- +Real data portability: TCX/GPX export, account export and a documented API
- +Two-year warranty, double the Fitbit and Amazfit norm
Cons
- −$199.99 for a screenless band with no GPS chip and no SpO2 — the $99.99 Amazfit Helio Strap does the same job
- −WR30 rather than 5 ATM, the weakest water rating in this comparison
- −8 days is the shortest battery life of any screenless band here
- −No ECG, no AFib detection, no FDA-cleared health feature
- −Polar Flow's interface is dated next to WHOOP's and Google Health's
WHOOP 5.0 (Peak membership)
Pros
- +Best-in-class recovery and sleep modelling — the Strain/Recovery framework is still the one everyone else copies
- +26Hz sampling and a 7% smaller module make it genuinely comfortable to sleep in
- +The wireless PowerPack means you never take the band off to charge it
- +HSA/FSA eligible, which softens the annual cost for some US buyers
Cons
- −There is no purchase price — you cannot own a WHOOP. Stop paying and the band stops collecting, uploading and analysing anything
- −$239/year for Peak means three years costs $717, more than four Fitbit Charge 6s
- −The $199 One tier quietly ships a certified pre-owned band and the old wired charger
- −No screen and no GPS chip: without your phone you get no pace, no route and no way to check anything mid-workout
- −Independent testing consistently finds wrist optical HR unreliable above ~150bpm, which is exactly where Strain is calculated
