Choose Fitbit Air if low cost and a lighter band matter most; choose Garmin CIRQA if you will use Garmin’s training metrics or connect it to compatible Garmin devices. The official US list prices are $99.99 for Fitbit Air and $199.99 for CIRQA—a $100 difference—but that premium buys a different feature set, not a universally better tracker.
How the two trackers compare
| Factor | Fitbit Air | Garmin CIRQA |
|---|---|---|
| Official US list price | $99.99, listed by Google in 2026. Google specifications | $199.99, listed by Garmin in 2026. Garmin product page |
| Battery life | Up to 7 days, according to Google; actual use and charging habits affect results. Google recommends charging every few days to maintain tracking. | Up to 10 days, according to Garmin; actual life depends on use. |
| Weight | 12 g with band; 5.2 g without band. | 14.8 g for the module; 20.7 g with the S–M band or 21.2 g with the L–XL band. |
| Training and ecosystem | Heart-rate, accelerometer/gyroscope, oxygen-saturation and device-temperature sensors are listed on Google’s specifications page. Sensor presence alone does not establish measurement accuracy. | Garmin documents more than 80 activity profiles, Body Battery, training readiness, and heart-rate broadcasting to compatible Garmin devices. |
| GPS and phone requirements | Setup and use require the Google Health app and a compatible phone. | Outdoor route tracking uses connected GPS with a compatible smartphone; the cited Garmin information does not establish onboard standalone GPS. |

What the extra $100 buys
Garmin training tools and device integration
CIRQA’s clearest case is for someone who wants Garmin’s documented training features or already uses a compatible Garmin watch or Edge computer. Garmin lists more than 80 activity profiles, Body Battery, training readiness and heart-rate broadcasting to compatible devices. These features can make CIRQA a more useful addition to an existing Garmin setup, rather than merely a more expensive step counter. Garmin’s product page describes its features and compatibility.
Garmin says core tracking does not require a subscription. Some additional capabilities, including certain coaching and AI features, are optional Connect+ features; check Garmin’s current terms to see what is included and what requires a paid plan. CIRQA is screen-free, according to Garmin’s July 2026 announcement.

Fitbit Air’s lower price and lighter build
Fitbit Air costs half as much at the cited US list prices and weighs 12 g with its band, compared with 20.7 g or 21.2 g for CIRQA with its two listed band sizes. Tom’s Guide also described Fitbit Air as smaller and lighter, though that comfort assessment is a reviewer’s judgment, not a controlled fit study. The published specifications are available from Google and Garmin.
Battery, wearability and everyday use
Garmin claims up to 10 days of battery life for CIRQA; Google claims up to 7 days for Fitbit Air. These are manufacturer maximums, not guarantees under every setting or use pattern. Google recommends charging Fitbit Air every few days if you want to maintain tracking. If minimizing charging is a priority, CIRQA has the higher stated maximum, but real battery life depends on how each band is used.

Tom’s Guide reports a 50 m water-resistance rating for both trackers. Its review also notes that CIRQA has a physical button and can optionally be worn on the arm. Those details may help with control and placement, but individual comfort and fit still depend on the wearer. Tom’s Guide’s hands-on account describes those observations.

In a one-hour Seattle walk, Tom’s Guide reviewer Dan Bracaglia manually counted 7,000 steps. Fitbit Air recorded 6,990 and CIRQA recorded 7,070. That single outing is a useful example of both devices recording a step count close to the manual tally in that specific test; it does not prove either tracker is more accurate overall.

The reviewer also reported that Fitbit Air’s climb result was far off, while CIRQA logged the activity as a generic workout and did not provide distance, climb or pace in that test. Activity setup and the kind of metric you need therefore matter: a step count alone is not a full account of a workout. Read the test’s conditions and results in Tom’s Guide’s comparison.

Which tracker should you buy?
- Choose Fitbit Air if the $99.99 US list price, lighter listed weight and straightforward everyday tracking better match your priorities.
- Choose Garmin CIRQA if you expect to use Garmin’s training features, heart-rate broadcasting to a compatible Garmin device, or its longer stated maximum battery life enough to justify paying $100 more at the cited US prices.
- Check phone and GPS needs first. Fitbit Air requires the Google Health app and a compatible phone; CIRQA uses a compatible smartphone for connected GPS. Neither should be treated as having standalone onboard GPS based on the cited product information.
- Compare the included features with any paid extras you actually want. Garmin describes core tracking as subscription-free, while some optional capabilities require Connect+. Google and Garmin feature and plan terms can change, so review the current product details before purchase.
