Side-by-Side Comparison
| Spec | WHOOP 5.0 (Peak membership) | Withings ScanWatch Light (37mm) |
|---|---|---|
| Price | $239.00 | $249.95 |
| Release Year | 2025 | 2024 |
| GPS | None — no GPS chip. Route and pace exist only if the phone comes with you | Connected GPS at best — the Amazon listing advertises 'Connected GPS' using the phone, while Withings' own shop spec sheet does not list GPS at all. Sources conflict; either way there is no GPS chip in the watch |
| Display | None — screenless; the band shows nothing and every metric is app-only | Analogue hands plus a 0.63-inch grayscale OLED sub-display (282 PPI) |
| Rated Battery Life ( days) | 4 | 30✓ |
| 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 | Sources conflict: Withings' own shop page claims up to 35 days, while the Amazon listing title and launch coverage say 30 days. No SpO2 sensor is drawing power |
| Subscription Model | Mandatory. WHOOP does not sell the hardware at any price — Peak is $239/year and the band comes with it. WHOOP states it stops collecting, uploading and analysing your data once the membership ends | Optional — Withings+ adds cardiologist ECG review, the AI Health Assistant, NutriCare and Readiness scoring. One month is included. Withings does not publish the Withings+ price on its US product or subscription pages |
| Annual Subscription Cost ($) | 239 | Not published on Withings' US Withings+ page |
| Water Resistance | WHOOP markets the band as swim-safe; no ATM or IP figure is published in the 5.0 launch materials | 5 ATM / 50 m, swimproof |
| 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 | No ECG on the Light — Withings reserves ECG and AFib detection for ScanWatch 2 and Nova. The cardiologist ECG review sold under Withings+ therefore does not apply to this model |
| SpO2 Sensor | Yes — blood oxygen, included on the Peak tier | No — Withings explicitly omits the SpO2 sensor on the Light |
| Phone Compatibility | iOS and Android | iOS and Android via Withings Health Mate |
| 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 | Proprietary magnetic puck |
| Data Export | Member data download and a developer API while the membership is active; access to the archive follows the membership | Health Mate offers a full account data export in CSV, and Withings publishes a developer API |
| Warranty | 12 months | 24 months |
| Colors | Onyx SuperKnit (additional bands sold separately) | Black & Silver, White & Rose Gold, Green, Blue |

Pros & Cons
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
Withings ScanWatch Light (37mm)
Pros
- +A month or more per charge, by far the longest run time in this comparison
- +Stainless steel and real analogue hands — it passes as a watch, not a fitness band
- +CSV account export and a public API make your data genuinely portable
- +Two-year warranty and HSA/FSA eligibility
Cons
- −$249.95 buys no ECG, no SpO2 and no GPS chip — the 'Light' name is doing a lot of work
- −Sources conflict on both battery life (30 vs 35 days) and whether connected GPS is supported at all
- −The Withings+ features most people want, including cardiologist ECG review, need hardware this model does not have
- −Withings does not publish the Withings+ price on its US pages, so the real cost of ownership is unclear at purchase
- −The 0.63-inch grayscale sub-display shows very little at a glance
