Choose if	You want an FDA-cleared ECG on a screen-free strap and don't mind paying $359 a year for the membership that includes it.	You want daily recovery and sleep scores plus WHOOP Age and health alerts, and would rather pay $239 a year than buy a device outright.
Main trade-off	It costs $1,077 over three years, and its Blood Pressure Insights is a beta wellness estimate with no FDA clearance.	It costs $717 over three years with no hardware-only option, has no display, and keeps ECG and blood pressure for the $359-a-year Life tier.
Key specifications	Membership cost: $359 a year for Life, the only tier that includes the MG. Peak is $239 a year and One is $199 a year, both with a WHOOP 5.0 device. WHOOP's membership pages list yearly prices only. Memberships renew at WHOOP's then-current price until you cancel. What Life includes: The MG device, a Wireless PowerPack and a choice of band. It also includes everything in Peak: Healthspan with WHOOP Age, Pace of Aging, Health Monitor alerts and a real-time Stress Monitor. On top of that come Heart Screener with ECG, on-demand AFib detection and Blood Pressure Insights. Battery and charging: 14+ days per charge. A full charge takes about 2 hours. The Wireless PowerPack slides onto the sensor and charges it while you wear it. WHOOP says a fully charged PowerPack holds enough power for up to 30 days to fully charge the sensor. The join page calls the PowerPack that comes with Life waterproof. Display and GPS: No display or built-in GPS. You read your data in the WHOOP app. Sensors: WHOOP says its sensors capture data 26 times per second. The FDA's summary says the ECG reads from electrodes on the strap. WHOOP's launch release says you touch the ECG-conductive clasp to take a reading. Its heart health page says light sensors read your PPG pulse waveform overnight. ECG (Heart Screener): The FDA cleared the WHOOP ECG feature on April 4, 2025 (510(k) K243236) for adults 22 and older. It classifies a 30-second recording as AFib, normal sinus rhythm, low heart rate, high heart rate, inconclusive or unsuccessful. WHOOP says it isn't for people with known arrhythmias other than AFib, and isn't recommended with a pacemaker or ICD. It isn't available in every region. ECG study results: The study behind the clearance had about 540 subjects with a mean age of 60.4. The feature had 96.2% sensitivity for AFib and 99.4% specificity for sinus rhythm on classifiable recordings. The reference was a cardiologist's reading of a simultaneous 12-lead ECG. The feature called 11% of recordings inconclusive. Blood Pressure Insights: A daily systolic and diastolic range, estimated once a day from overnight sensor data. WHOOP calls it a beta feature for wellness and says it is not a medical device. You calibrate it with cuff readings you log in the app. WHOOP says your true value may be higher or lower than the range shown. It also says the feature isn't intended for use if you are pregnant or on blood pressure medication. FDA status of Blood Pressure Insights: No clearance is listed. The FDA's 510(k) records under WHOOP's name show only the ECG feature. In July 2025 the FDA told WHOOP it was marketing Blood Pressure Insights without clearance or approval. In June 2026 the FDA closed that warning letter, saying it doesn't intend to enforce device requirements for the feature as modified. The close-out letter doesn't say the feature is cleared, approved or validated. Trial and trade up: The one-month free trial uses a certified pre-owned WHOOP 5.0 device on Peak, not an MG. WHOOP says free trials of Life aren't available. Trading in an eligible Oura Ring, Apple Watch, Garmin or Samsung watch takes up to $119 off the first year, and a Fitbit is worth $30. You have 30 days to ship the old device and charger. If you don't, WHOOP may suspend the membership or charge you the discount. Upgrading to MG: Current members can move up to Life at any time and get a new MG device. WHOOP's membership page says you pay a prorated amount. Its terms also describe a membership extension or a one-time upgrade fee, and give no amount for the fee.	Membership cost: $239 a year for Peak. One is $199 a year and Life is $359 a year. WHOOP shows only annual pricing. Battery and charging: 14+ days per charge. A full charge of the strap or the PowerPack takes about 2 hours. The Wireless PowerPack slides onto the strap and charges it while you wear it. WHOOP says a fully charged PowerPack holds enough power for up to 30 days to fully charge the sensor. Display and GPS: No display or built-in GPS. You view your data in the WHOOP app. Sensors: WHOOP says its sensors capture data 26 times per second. It doesn't name the sensor types. Peak-tier features: Healthspan and Pace of Aging (WHOOP Age), a real-time Stress Monitor and Health Monitor alerts, plus everything in One. In the box: WHOOP 5.0 device, Wireless PowerPack and SuperKnit band. One members get a wired Basic Charger and CoreKnit band instead.
