The two biggest names in mainstream wearables both shipped screenless trackers in 2026, ten weeks apart. Google's Fitbit Air arrived in May at $99, betting on lightness and simplicity. Garmin answered in July with the $199.99 CIRQA, stuffing nearly every metric from its sub-$500 watches into a pod with no display. Neither requires a subscription, which makes this the rare comparison where the sticker price is the real price.
The question is simple: is Garmin's extra $100 of training depth worth it, or is the Air's do-less-weigh-less approach actually the smarter buy?

Same shape, different species
Strip the marketing and the two products separate cleanly. The Air is a health monitor: heart rate around the clock, sleep stages, SpO2, skin temperature, AFib alerts, all captured passively by a 12-gram pebble and presented as tidy charts in Google Health. It is the tracker for someone who wants awareness without homework.
The CIRQA is a training instrument wearing a health monitor's body. Under the fabric strap sits the same physiology engine as a Forerunner: Training Readiness each morning, acute load and load ratio across the week, VO2 max trends, recovery time after sessions, Body Battery through the day. DC Rainmaker's summary was apt: everything from Garmin's mid-range watches, just without the screen.
The gym test
This is where the $100 gap earns its keep. The CIRQA auto-counts reps, lets you button-start any of 80-plus workout types, and broadcasts live heart rate over ANT+ and Bluetooth to treadmills, spin bikes and apps like Zwift. The Air has no button and no broadcast, and reviewers consistently call its workout software the weakest part of an otherwise strong product; PCMag noted you even need Premium to import data from services like Peloton.
If your week contains deliberate training, intervals, lifting, classes, the Garmin simply respects it more. If your movement is walks, commutes and the occasional gym visit, the Air's automatic detection covers it and the extra metrics would sit unread.
Comfort, battery and living with them
The Air is the most forgettable wearable either company has made: 12 grams, low profile, a week of battery with a fast-charge that adds a day in minutes. The CIRQA runs up to 10 days but wears bigger; Trusted Reviews found the module bulkier than they would like and the strap options too sporty for everyday dress. Neither has a screen to crack or notifications to silence, which is the entire point of the category.
Ecosystems and getting your data out
Both are good citizens. Air data lands in Google Health and flows through Health Connect on Android; Garmin Connect syncs to both Apple Health and Health Connect. That means either feeds the rest of your stack, including Fitcoin, which scores the same steps and workouts into FitScore, pays out partner rewards and adds Sleep, Recovery and Energy insights. Our Fitbit Air rewards guide covers the exact plumbing.
Verdict: which one should you buy?
Choose Fitbit Air if:
- You want the cheapest, lightest credible screenless tracker.
- Passive health monitoring and sleep are the whole job.
- AFib detection at $99 matters to you or a family member.
- You live in the Google ecosystem already.
Choose Garmin CIRQA if:
- You train with intent and want readiness, load and VO2 max without a subscription.
- Rep counting, button-started workouts and HR broadcast fit your gym routine.
- You already own Garmin gear; CIRQA merges into Unified Training Status.
- You want the closest thing to Whoop with no annual fee.
Our take: buy the Air if the tracker is a health habit, buy the CIRQA if it is training equipment. Both are honest products at honest prices, which makes this the friendliest rivalry in wearables right now.
Frequently asked questions
Is the Garmin CIRQA worth $100 more than the Fitbit Air?
For people who train, usually yes: you get Training Readiness, VO2 max, training load, rep counting, a workout button and ANT+ heart rate broadcast, none of which the Air offers. For passive health and sleep tracking, the $99 Air covers the essentials and is lighter and more comfortable.
Do the Fitbit Air or Garmin CIRQA need subscriptions?
Neither requires one. The Air's core tracking is free in the Google Health app, with Google Health Premium optional at $9.99 a month. CIRQA's health and training metrics are free in Garmin Connect, with Connect+ optional at $10.99 a month.
Which is lighter, Fitbit Air or Garmin CIRQA?
The Fitbit Air at about 12 grams against roughly 20 grams for the CIRQA with its band. Reviewers also note the CIRQA module is comparatively bulky and sporty-looking.
Which has better battery life?
Garmin CIRQA claims up to 10 days against about 7 for the Fitbit Air. Enabling the CIRQA's Pulse Ox monitoring reduces its figure.
Can either track workouts at the gym properly?
The CIRQA is far better: automatic rep counting, 80+ manual workout types via its button, and it broadcasts heart rate to gym equipment over ANT+ and Bluetooth. The Air auto-detects common activities but its workout software is the weakest part of the product.
