Whoop 5.0 vs Whoop MG: What's the Difference?
Whoop's 2025 generation split the lineup in a way that still confuses buyers: Whoop 5.0 and Whoop MG are siblings, not rivals. Both are 7% smaller than the 4.0 with battery life stretching past two weeks. The real difference is the membership tier — the MG hardware, with its on-demand ECG and blood-pressure trends, only comes with the top 'Life' plan. Here's how to pick without overpaying.

Round 1: What's actually different
Both devices share the same core upgrades over Whoop 4.0: noticeably smaller and lighter, a much faster processor with quicker syncing, and battery life that realistically reaches two weeks. Day to day, strapped to your wrist, they feel identical.
The MG ("medical grade") adds hardware most users will touch occasionally: an on-demand ECG for spot checks with irregular-rhythm (AFib) notifications, plus a daily blood-pressure trend estimate. Useful — but only if those specific features answer a question you actually have.
Round 2: The membership maze
Whoop One ($199/yr) gets you the 5.0 hardware with core Sleep, Strain, Recovery, and Women's Hormonal Insights. Peak ($239/yr) adds Healthspan (Whoop Age, Pace of Aging), the Health Monitor, and real-time stress tracking — still on 5.0 hardware. Life ($359/yr) is the only way to get MG hardware.
That structure means the MG question is really: is ECG + blood-pressure trending worth $120–160 more per year, forever? For most healthy users tracking training and sleep, the answer reviewers keep reaching is no — Peak on the 5.0 is the sweet spot.
Round 3: Women's Hormonal Insights
The good news for this site's readers: Whoop's Women's Hormonal Insights — AI-driven guidance on how hormonal fluctuations across cycle phases and life stages affect recovery, sleep, stress, and training — is available on every tier, including the cheapest One plan.
You do not need the MG or the Life plan for any women's-health feature. Cycle-aware training guidance works identically on both devices, which removes the most tempting upsell argument for this audience.
Round 4: Who genuinely needs the MG?
If you have a personal or family history of arrhythmia, are in perimenopause and tracking cardiovascular changes, or your doctor has suggested keeping an eye on blood pressure trends, the MG's sensors provide data worth discussing at appointments — though it is not a diagnostic device and doesn't replace a cuff or a clinical ECG.
If that paragraph didn't describe you, the 5.0 on the Peak plan delivers effectively the whole Whoop experience — including Healthspan and stress monitoring — at a meaningfully lower annual cost.
Cost & subscription
Whoop bundles hardware into the membership: One $199/yr and Peak $239/yr (both 5.0 hardware), Life $359/yr (MG hardware). These are membership prices, not device prices — there is no way to buy the hardware outright.
Choose Whoop 5.0 (Peak) if: you want Whoop's full training, sleep, stress, and Healthspan experience. This is the right pick for most people — Women's Hormonal Insights included at every tier.
Choose Whoop MG (Life) if: on-demand ECG, AFib notifications, or blood-pressure trends answer a real health question for you — ideally one you're already discussing with a clinician. Otherwise you're paying a permanent premium for sensors you'll rarely open.
