Fitness Trackers / WHOOP
WHOOP MG (Life membership)
FDA-cleared ECG on a screenless band you never own, at $359 every single year.
Overall score 4.6/10
Pros
- + One of the very few wrist wearables with an FDA-cleared ECG and AFib detection
- + Everything Peak offers plus longevity/Healthspan metrics and priority support
- + Wireless PowerPack included, so the band never leaves your wrist
- + HSA/FSA eligible
Cons
- − $359/year, forever — the MG cannot be bought outright and stops working as a tracker when the membership lapses
- − The headline Blood Pressure Insights feature is explicitly not FDA-cleared and drew an FDA warning letter in July 2025
- − Early MG units suffered widely reported sensor failures within hours of setup in May 2025
- − No screen and no GPS chip despite costing more per year than most GPS running watches cost outright
- − The ECG contacts do not change the fact that Strain is still computed from wrist PPG, which degrades at high intensity
WHOOP MG (Life membership) review: what the specs say
FDA-cleared ECG on a screenless band you never own, at $359 every single year. At $359, 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 4.6/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Health Features at 9.0/10 — depth of the health sensor suite and how much of it is FDA-cleared and enabled in the US.. The weakest is Subscription Freedom at 0.5/10, 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: $359/year, forever — the MG cannot be bought outright and stops working as a tracker when the membership lapses; and the headline Blood Pressure Insights feature is explicitly not FDA-cleared and drew an FDA warning letter in July 2025. 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.
