CIRQA vs WHOOP vs LOOP vs Fitbit Air vs Helio Strap Pro

You’ve seen the spec table comparisons elsewhere; the comparisons here should be more useful for you.

I’ve used all the 5 main screenless trackers, some for many years, and this article tells you what each one is best for and analyses them all against all the real criteria that you use when making a buying decision like “Does it actually look good?”.

What each band is best at

None of these has GPS, and all work on iOS or Android.

• CIRQA is superb for existing Garmin owners who want a screen-free device to complement their watch or Edge. Also a great entry point for anyone into the feature-packed Garmin Connect ecosystem.
• LOOP is made well and offers a subscription-free way into a good but dated app.
• WHOOP 5.0 is the pick for anyone making a lifestyle statement. It has the best app and sport auto-detection, great at understanding your recovery and coaching you toward fitness goals. The MG tier and Life subs add super interesting blood panel correlations.
• Helio Strap ties as the cheapest option here and has a surprisingly good app. Its Pro option is built specifically for niche aspects linked to hybrid training (HYROX).
• Fitbit Air ties Helio Strap as the cheapest option, and is the lightest and easiest device here to swap bands on.

Price and subscription

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
$199.99, no subs	(Optional Connect+ $69.99/yr)	$199.99, no subs	$199/yr (One), $239/yr (Peak), or	$359/yr (Life, includes MG hardware)	$99.99, no subs	Pro is $199.99	$99.99, no subs	(optional Google Health Premium, $99.99/yr)

Verdict: Amazfit Helio Strap and Fitbit Air are tied as the cheapest at $99.99 with no subscription, so there’s no outright winner on price alone. Many key calls come down to whether you need the niche features that are in the optional subs, e.g. you need Fitbit’s subs to get the AI features. Whilst there is no choice with Whoop’s subs, there are tiers of subs, and there are compelling health features in the higher price tier for those who can afford it.

Aesthetics and bands

These devices need you to want to wear them all day, every day. They have to look and feel good in every situation.

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
4 colourways, official bands only ($49.99 wrist, $59.99 arm); third-party straps already on Amazon. Super fiddly to change straps. LED hard to see if recording.	6+ colours, $30 each, first-party only so far	SuperKnit bands, largest and longest-standing aftermarket and apparel market of any device here	Wrist, arm and waist options included, first-party only	Widest first-party range at launch from $34.99, third-party straps already available, lightest at 12g.

Verdict: Fitbit Air is simply too narrow for many (good for many women perhaps) but looks cheap. WHOOP’s bands generally look fantastic, and they are easier to change than all but the Fitbit. CIRQA feels big on the wrist but in reality not too different from the Polar and Amazfit.

App quality

The band is dumb. All your insights come from an app you’ll use every day. Most of the apps have what most people need… somewhere. But usability is the feature you will use every day.

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
Garmin Connect: mature, deep training data, complex app	Polar Flow: does the job well, it just doesn’t look great	Strongest in class, benchmark for a coaching, recovery and medical-adjacent experience	Zepp App: impressively solid but less polished than Garmin or WHOOP	Google Health: clean and simple to use. Coaching needs subs

Verdict: The polish and usability of WHOOP’s app remains the standard the others are judged by, while CIRQA wins by being part of an expansive sports ecosystem.

Button and autodetect quality

The band has to either auto-detect exercises near perfectly or let you manually start and stop them.

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
Physical button plus auto-detection. Excellent	Decent auto-detection but no button	No button, but class-leading auto-detection	No button, decent detection. Advanced detection from the Pro pods	No button, good auto-detection

Verdict: CIRQA plays the trump card for me with its button. Beyond that, WHOOP sets the detection benchmark.

Differentiator

The differentiators answer why each product exists as it does.

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
A complementary purchase or gateway product to Connect	A cheap WHOOP wannabe	Excellence and status, for a price	Another cheap Whoop wannabe, but the Pro model gives unique HYROX insights	Exists to get your data to train its AI model; that’s why it’s cheap

Verdict: Each device has one clear reason to exist beyond the others, from Helio Strap Pro’s unique HYROX data to Fitbit Air’s data grab.

Battery

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
10 days	8 days	14 days	Wrist or arm sensor 7-11 days, waist pod up to 40+ days	7 days

Verdict: They all have good or excellent battery life plus an annoyingly unique charging cable/cradle.

Positioning

CIRQA	LOOP	WHOOP 5.0	Helio Strap Pro	Fitbit Air
Companion to a Garmin watch or Edge, general fitness and wellness	Companion to a Polar watch, everyday recovery and activity, or Whoop competitor	General recovery and strain optimisation	Companion to an Amazfit Balance 3 or Balance Ultra, or Whoop competitor	General wellness and light activity tracking, not really intended as a Pixel Watch companion

Verdict: One key use of CIRQA is as the companion device. But CIRQA, LOOP and Helio are all Whoop competitors to some degree. Fitbit Air is perhaps targeting the budget and female markets more.

Quick answers

Which of these screenless trackers is cheapest overall?
The Amazfit Helio Strap and Fitbit Air both start at $99.99 with no required subscription. Helio Strap Pro, CIRQA and Polar LOOP sit at $199.99 as one-time purchases. WHOOP is the only device bundled into an annual membership, starting at $199 per year.

Does WHOOP require a subscription?
Yes. WHOOP hardware is bundled into membership rather than sold separately. Tiers run from $199 per year (One) up to $359 per year (Life), which is the only route to the WHOOP MG hardware with its ECG and blood pressure trend features.

Do I need an Amazfit watch to use Helio Strap Pro?
Yes, for the full system. The waist motion pod and its HYROX per-station analysis require pairing with a Balance 3 or Balance Ultra. The arm or wrist heart rate sensor alone works as a standalone tracker without a compatible watch.

Which of these trackers has a physical button?
Garmin CIRQA is the only device in this group with a physical button, letting you manually start an activity, snooze an alarm or broadcast heart rate without opening the app. LOOP, WHOOP, Helio Strap Pro and Fitbit Air are all buttonless and rely on autodetection or the app.

WHOOP vs Fitbit Air: which should I buy?
WHOOP wins on app depth, workout autodetection and battery life at 14 days versus 7, and the MG tier adds an ECG option Fitbit Air doesn’t offer. Fitbit Air wins on price at $99.99 with no required subscription, and is the lightest device in this comparison at 12g. Choose WHOOP for serious training and recovery coaching, Fitbit Air for casual wellness tracking without a recurring cost.

Is Polar LOOP or WHOOP better?
WHOOP has the stronger app and remains the benchmark for autodetection and coaching depth in this category. Polar LOOP is the cheaper option with no subscription required, and fits naturally alongside an existing Polar watch. Buy WHOOP for the deepest recovery insight, LOOP for a one-time purchase within the Polar ecosystem.

Fitbit Air vs Amazfit Helio Strap: which is cheaper?
Both launch at $99.99 with no required subscription, so there’s no price winner between them. Fitbit Air is lighter and has the widest band selection at launch. The Amazfit Helio Strap has a slightly more polished app and, via its Pro tier, unique HYROX-specific tracking that Fitbit Air doesn’t attempt.

Is WHOOP more accurate than Fitbit Air?
WHOOP’s workout autodetection is generally rated ahead of Fitbit Air’s by reviewers, and its longer track record in the category gives it an edge in workout classification. Neither device has been benchmarked against a chest strap in this comparison, so treat autodetection accuracy claims as directional reviewer consensus rather than lab-verified data.

CIRQA vs WHOOP: which should I buy?
CIRQA is the cheaper one-time purchase at $199.99 with no required subscription, and it’s the only device here with a physical button. WHOOP costs more over time but delivers a deeper app, stronger autodetection and, on the MG tier, ECG and blood pressure tracking. Choose CIRQA if you already own a Garmin watch and want a no-subscription companion, WHOOP for the more capable app and coaching.

CIRQA vs Fitbit Air: which is better?
CIRQA costs more upfront at $199.99 versus Fitbit Air’s $99.99, but includes a physical button and ties into the wider Garmin Connect ecosystem. Fitbit Air is lighter, cheaper and has the widest band range at launch. Existing Garmin owners get more value from CIRQA; everyone else, Fitbit Air is the easier buy.

CIRQA vs Amazfit Helio Strap: which should I buy?
Both are one-time purchases with no required subscription, though CIRQA is $199.99 against the base Helio Strap’s $99.99. CIRQA has a physical button and full Garmin ecosystem integration; the Helio Strap Pro adds unique HYROX-specific muscular load tracking that CIRQA doesn’t attempt. The right choice depends on which ecosystem, Garmin or Amazfit, you’re already in.

CIRQA vs Polar LOOP: which is better?
Both cost $199.99 with no subscription, so price isn’t the deciding factor. CIRQA has a physical button and feeds into Garmin Connect; Polar LOOP is buttonless with a plainer app but fits naturally alongside a Polar watch. Buy the one that matches the watch brand you already own.
