Garmin Cirqa vs WHOOP: Which Screenless Band Should You Buy?

Buy the Garmin Cirqa if you want screenless sleep and recovery tracking without paying every year. It's about £179 once, the core health data lives in the free Garmin Connect app, and the band costs less than a single year of WHOOP Peak. Pick WHOOP only if you train hard most days, want its Strain score telling you how much to do, and value a 14 day battery you can top up without taking the band off. For everyone else, and especially anyone already on Garmin, the Cirqa is the better buy.

Both are the same idea: a small sensor pod on a fabric strap, no display, everything read on your phone. The difference is the business model, and that decides more than any sensor.

Price: one receipt against a rental

This is the whole argument for most buyers. The Cirqa was £179 on Amazon UK when we checked, and nothing you need is locked behind a subscription. Amazon's listing says heart rate, Body Battery, stress, Pulse Ox and women's health tracking all come through the free Garmin Connect app.

WHOOP doesn't sell you a band. You buy a membership, the hardware comes with it, and if you stop paying there's nothing left to read. Peak was £229 for 12 months on Amazon UK at the time of writing, and UK coverage has put One at £169 and Life at £349 a year.

Run it over two years and the gap is wide:

Two-year cost	Total
Garmin Cirqa	about £179
Garmin Cirqa plus upper arm band	about £229
WHOOP One	£338
WHOOP Peak	£458
WHOOP Life	£698

So the Cirqa with the extra arm band still costs the same as one year of WHOOP Peak. By year three you're £400 or more ahead. Our WHOOP Peak review goes through the membership model properly, and it's the same story we found in Garmin vs WHOOP with Garmin's watches.

Garmin does have its own optional subscription. Connect+ adds live activity view, Garmin Coach training plans, nutrition tracking and the Active Intelligence AI insights. It's not needed for the recovery side, but there's one annoyance: watching your heart rate in real time during a workout sits behind it. On a screenless band that's the only way to see anything mid-session, so if you want that, budget for Connect+ or pair a chest strap with something that has a screen.

Battery and charging

WHOOP wins, and the charging design matters as much as the headline number. The 5.0 is rated at 14 plus days and its battery pack slides on while you wear it, so you never miss a night. The Cirqa is rated at up to 10 days on Amazon's listing, comes off to charge on Garmin's own cable (not USB-C), and turning on all-day Pulse Ox cuts into that figure.

Ten days is still plenty. Charge it on Sunday mornings and you'll rarely think about it. The real risk with any off-wrist charging is forgetting to put it back on, which is how a week of sleep data quietly disappears.

Sensors and hardware

On paper there's less between them than the price gap suggests. The Cirqa has Garmin's optical heart rate sensor with skin temperature, Pulse Ox (off by default), and an accelerometer, according to detailed spec breakdowns, but no gyroscope and no built-in GPS. Pair it with your phone and outdoor runs and rides pick up distance and pace from the phone's GPS. A single button on the pod lets you start an activity without opening the app.

WHOOP's 5.0 covers heart rate, HRV, resting heart rate, respiratory rate and skin temperature, with no screen and no GPS either. Its ECG and blood pressure insights only come with the Life tier and the WHOOP MG hardware, so at Peak and One the sensor lists look similar.

One quiet win for Garmin: the owner's manual says the Cirqa can broadcast heart rate to a Garmin Edge bike computer, so it doubles as a ride sensor.

Recovery scores: Body Battery vs Recovery and Strain

This is the part people actually buy these bands for, and the two take different routes.

WHOOP gives you three numbers. Recovery is your morning readiness, built largely from overnight HRV, resting heart rate and sleep. Strain tracks how hard your day was on a 0 to 21 scale and gives you a target based on how recovered you are. Sleep Performance compares what you got against what you needed. For someone training six days a week, that Strain target is the one feature Garmin doesn't copy directly, and it's the best reason to pick WHOOP.

Garmin spreads the same job across several features. Body Battery is an energy gauge that charges with sleep and rest and drains with activity and stress. Sleep score grades the night and comes with coaching on how much you need, plus sleep stages, naps and a sleep alignment view that shows how closely you track your circadian rhythm. HRV status compares your overnight HRV against your own baseline and needs about three weeks of wear to settle. Spec breakdowns also list Training Readiness and training load on the Cirqa, which brings it closer to WHOOP's Strain model than Garmin's earlier fitness bands.

WHOOP's version is tidier and more opinionated. Garmin's is more spread out but gives you more to look at, and nothing on the recovery side costs extra.

Accuracy: what the research says

Nobody has tested the Cirqa against WHOOP yet, so treat any "more accurate" claim with suspicion. The best evidence uses older hardware from both brands.

A 2025 study tracked 13 adults over 536 nights against a Polar H10 chest strap. WHOOP 4.0's overnight HRV was out by about 8% on average, while the Garmin Fenix 6 was out by about 10.5%, just over the study's 10% threshold (validation of nocturnal resting heart rate and HRV in consumer wearables). That's a lean towards WHOOP on HRV, from a small group and from a watch rather than a band.

For sleep, a 2024 systematic review of studies against polysomnography found WHOOP was within 1.4 minutes of lab total sleep time on average but overestimated REM by 21 minutes. The Garmin Vivosmart 4 overestimated total sleep by about 47 minutes and was poor at spotting time awake, though that figure rests on only two studies (Fitbit Charge 4, Garmin Vivosmart 4 and WHOOP vs polysomnography). The authors said all three need work on sleep stages.

So WHOOP has the better published record, on older kit. In practice, both are trend trackers. Watch how your HRV and sleep move over weeks, not what last night's REM figure says.

Wear location and comfort

Both are light fabric bands built to be forgotten about overnight, which is the point of going screenless. The Cirqa pod is small and the complete band weighs around 21g in the L/XL size. Garmin sells an upper arm band (about £50 extra) and you set the wear position in Garmin Connect. WHOOP offers bicep and body-wear options too.

Arm wear matters more than it sounds. Lifters who find a wrist pod digs in during presses or catches on a barbell will get on better with either band on the upper arm.

Apps and ecosystem

If you already wear a Garmin watch, this settles it. The Cirqa drops into the same Garmin Connect account, and the app is free, deep and works on iPhone and Android. WHOOP's app is cleaner and more focused, with coaching built into every tier, but it's a closed system and it's all you get.

Who should buy which

Buy the Garmin Cirqa if you want sleep, HRV and Body Battery data without a yearly bill, you already use Garmin Connect, or you're curious about screenless tracking and don't want to commit £169 a year to find out. It's also the pick if you'll keep a tracker for three years or more, where WHOOP's costs really pile up. Our Garmin Cirqa review covers it in more depth.

Buy WHOOP if you train hard most days and want a Strain target to steer the dose, you hate charging and want the 14 day battery, or you'll use WHOOP Peak's health extras. Go in knowing you're renting it.

If the Cirqa still feels like a lot for a band with no screen, the Fitbit Air is cheaper again. We compare it with the Cirqa in Garmin Cirqa vs Fitbit Air and with WHOOP in Fitbit Air vs WHOOP.
