Fitness Trackers / WHOOP
WHOOP 5.0 (Peak membership)
The best recovery analytics in wearables, rented for $239/year and never owned.
Overall score 4.7/10
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
WHOOP 5.0 (Peak membership) review: what the specs say
The best recovery analytics in wearables, rented for $239/year and never owned. At $239, WHOOP's 2025 model sits at the premium end of the category — the fitness Trackers we compare run from $51.99 to $359. It scores 4.7/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Tracking Accuracy at 8.0/10 — how closely steps, heart rate and sleep match reference devices — and how badly the optical sensor falls apart at high intensity.. The weakest is Subscription Freedom at 1.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: there is no purchase price — you cannot own a WHOOP. Stop paying and the band stops collecting, uploading and analysing anything; and $239/year for Peak means three years costs $717, more than four Fitbit Charge 6s. Every specification on this page comes from WHOOP's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| GPS | None — no GPS chip. Route and pace exist only if the phone comes with you |
| Display | None — screenless; the band shows nothing and every metric is app-only |
| Rated Battery Life | 4 days |
| What the Battery Claim Assumes | 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 | 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 | 239 $ |
| Water Resistance | 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 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 | Yes — blood oxygen, included on the Peak tier |
| Phone Compatibility | iOS and Android |
| Charger | 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 | Member data download and a developer API while the membership is active; access to the archive follows the membership |
| Connectivity | Bluetooth |
| Material | Woven SuperKnit band with polymer sensor module |
| Warranty | 12 months |
