Performance Metrics

Garmin CIRQA

WHOOP MG

Measurement Accuracy

Evaluates accuracy, repeatability, and reliability of heart rate, sleep, activity, blood pressure, SpO2, HRV, stress, and recovery measurements, including comparisons with appropriate references when available.

CIRQA brings over Garmin's training stack: HRV status, training readiness, training status, VO2 max, Pulse Ox, and sleep score. Those metrics have a long history on Garmin watches. This band is new, it has no ECG, and GPS is the phone's. The 89 is a score of that published set. Medgrade did not bench it against a chest strap or a sleep lab.

The MG's optical set covers heart rate, HRV, sleep, skin temperature, and blood oxygen, and the ECG used for on-demand AFib screening is FDA-cleared. Blood Pressure Insights remains a wellness trend: the FDA's closeout letter covers the feature only as modified, and it is not a validated cuff. This 94 reflects that sensor set and the ECG clearance. Medgrade did not run a cuff or chest-strap comparison for this review.

App Experience

Evaluates companion-app usability, dashboards, visualization, trends, reporting, insights, integrations, connectivity, and data synchronization reliability.

Garmin Connect is the record: sleep, training status, Body Battery, and activity history, with no fee for those views. It is a dense app. The band cannot show a number on its own, so every check is a phone check. ANT+ is there for people who already use Garmin sensors.

The WHOOP app is the entire interface. It shows strain, recovery, sleep, and Healthspan, and an ECG can be exported as a PDF. Membership is what unlocks it. There is no on-wrist screen to fall back on when the phone is away.

Hardware & Wearability

Evaluates construction, durability, sensor contact, comfort during daily wear and sleep, straps, battery life, charging, water resistance, and ergonomics.

A 14.8 g module on a fabric strap is light for all-day and overnight wear, and the 5 ATM rating covers swimming. Ten days of battery is a clear step down from the 14-day claims on WHOOP MG and Hume Band 2.0, and from the Band XS Pro's longer low-power mode. The side button is the one on-wrist control.

WHOOP states 14 or more days of battery, an IP68 rating to 10 meters, and a band about 7 percent smaller than the prior model. The clasp-style sensor is built for 24-hour wear, including sleep. Straps beyond the one in the membership are a separate purchase, and the band charges in a PowerPack rather than from a simple cable on the wrist.

Overall Value

Evaluates purchase price, subscriptions, included features and accessories, warranty, recurring costs, and competitiveness against alternatives.

At $199.99 with no required fee, CIRQA undercuts a year of WHOOP Life and lands near Polar Loop. You get Garmin's training metrics rather than an ECG. Fitbit Air is about half the price with a shorter battery and a thinner training story. The score sits under the Band XS Pro's 96 because $199.99 buys less endurance and no second strap in the box.

+2% better overall value

Year-one cost is $359, and the same amount is due each year the membership continues. Over three years that is $1,077 before any extra strap. The ECG and the depth of the app are what the fee buys. Bands in this comparison that sell the hardware once, with no required fee, score higher on value even when their sensor list is shorter.

Expert Review Summary

Our clinical assessment and verdict for each device

Garmin CIRQA

Recommended

"Garmin's training metrics in a 14.8 g band, for $199.99 once, with a 10-day battery and no ECG."

Garmin CIRQA scores 89/100: Hardware and Wearability 90, Measurement Accuracy 89, App Experience 88, Overall Value 88. Garmin announced it on July 21, 2026 at a suggested $199.99, with no subscription for the listed health and training features. The module is 14.8 g, battery life is up to 10 days, and the water rating is 5 ATM. Sleep, Pulse Ox, HRV status, training readiness, VO2 max, and Body Battery are read in Garmin Connect. Outdoor routes use the phone's GPS. There is no ECG. This 89 is an editorial reading of Garmin's specifications, not the eight-user protocol behind the Band XS Pro scores.

WHOOP MG

Recommended

"An FDA-cleared wrist ECG and a mature recovery app, tied to a $359 yearly membership that you cannot skip."

WHOOP MG scores 92/100 on the four comparison categories: Measurement Accuracy 94, App Experience 94, Hardware and Wearability 92, and Overall Value 86. WHOOP announced the band on May 8, 2025 as the hardware for WHOOP Life. The company states 14 or more days of battery life, continuous heart rate, HRV, sleep, skin temperature, and blood oxygen, and an FDA-cleared ECG for AFib screening in adults 22 and older who do not have a pacemaker. Blood Pressure Insights is a separate wellness trend. The FDA warned WHOOP about that feature on July 14, 2025, then closed the warning after WHOOP changed the product and its labeling. The closeout is not a clearance to diagnose hypertension. The 92 is an editorial score of those published facts. It is not a second copy of the 12-week, eight-user protocol used for the Oxiline Band XS Pro.
