Wearable Comparison
Quick Verdict
Fitbit Air costs $99.99 and has no screen. The cheapest Apple Watch, the SE 3, starts at $249, and the Series 12 starts at $399. If you want a device that reads heart rate, sleep and blood oxygen in the background and then leaves you alone, Fitbit Air does that for a quarter of the price of a Series 12 and runs for about a week between charges rather than a day. If you want a wrist computer that guides a workout in real time, takes an ECG and shows notifications, only the Apple Watch does that, and the entry fee is at least $249.
Now the catch, and it is the part most comparisons skip. The $99.99 is not the whole bill. Fitbit Air ships with a three month trial of Google Health Premium, which costs $9.99 a month afterwards, and Google puts features such as coach recommended guided workouts behind it. Apple charges no monthly fee for the health features on the watch. Keep Premium for two years and the Fitbit Air path costs roughly $310 in total, which is more than an Apple Watch SE 3 at $249 and not far off a Series 12. The screenless band is only decisively cheaper if you intend to stay on the free tier, so decide that before you buy, not after the trial lapses.
Price, Battery and the Monthly Fee
These are the current US starting prices from Apple's own buy pages and Google's Fitbit Air announcement, checked on September 16, 2026.
| Device | Starting price | Battery, normal use | Screen | Monthly fee |
|---|---|---|---|---|
| Fitbit Air | $99.99 | Up to a week | None | Google Health Premium at $9.99 after a three month trial |
| Apple Watch SE 3 | $249 | Up to 18 hours | Yes | None |
| Apple Watch Series 12 | $399 | Up to 24 hours | Yes | None |
| Apple Watch Ultra 4 | $799 | Up to 50 hours | Yes | None |
The battery column is the gap people underestimate. An Apple Watch is a daily charging habit, and the Series 12 is rated for up to 10 hours during an outdoor workout, so a long training day plus a night of sleep tracking is a real planning problem. Apple has softened it with speed rather than capacity: 15 minutes on the charger now returns up to 12 hours. Fitbit Air takes the other route and simply lasts, with five minutes of charging buying a full day.
What Each One Actually Measures
Screenless does not mean sensor poor. This table compares Fitbit Air against the Series 12, the mainstream Apple Watch, using each company's own descriptions.
| Capability | Fitbit Air | Apple Watch Series 12 |
|---|---|---|
| Starting price | $99.99 | $399 |
| Display | None, a small pebble that pairs with the Google Health app | Full display with apps and notifications |
| Heart rate | 24/7 optical heart rate | Measured every five seconds all day |
| Heart rate variability | Yes | Yes, sampled up to 24 times more often than the previous generation |
| Blood oxygen | SpO2 | Blood Oxygen app |
| Heart rhythm | Heart rhythm monitoring with Afib alerts | ECG app |
| Sleep | Sleep stages and duration | Sleep tracking with a nightly sleep score and apnea notifications |
| Fast charge | Five minutes for a full day | 15 minutes for up to 12 hours |
The honest summary is that for passive vitals the two are closer than the price gap suggests. Where Apple pulls ahead is in the things a sensor alone cannot do: an on demand ECG, hypertension notifications, and an interface that tells you something while you are still wearing it. Note one regional caveat on hypertension. Apple's own feature availability page says hypertension notifications "may not be available on Apple Watch Series 12 or Ultra 4 in your region, as additional regulatory clearances for these devices are in process", so check before buying a Series 12 specifically for that feature.
Which Apple Watch Actually Competes
"Apple Watch" is now three different products, and the answer to this comparison changes depending on which one you mean.
The SE 3 at $249 is the one a Fitbit Air buyer realistically cross shops, and it is the most limited. Apple's SE buy page lists it without an ECG app, without a Blood Oxygen app and without hypertension notifications. So the cheapest Apple Watch gives up two heart and blood measurements that a $99.99 Fitbit Air performs. If those specific readings are why you are shopping, the SE 3 is the wrong Apple Watch and the Fitbit Air is the better value.
The new Readiness app, which reports a single score from 0 to 10 with a recommendation of Recover, Pace Yourself, Ready or Go For It, is the other thing to know. Readiness is tied to the new Health Sensing System, so it runs on the Series 12 and Ultra 4 and does not arrive on older watches that install watchOS 27. Gadgets and Wearables, reading the same watchOS 27 release, reports the Series 9, 10 and 11, the Ultra 2 and Ultra 3, and the SE 3 all miss it. If a daily readiness number is the point of the purchase, that is a $399 floor, not a $249 one. We covered the cutoff in detail in which Apple Watch models run Readiness.
Sleep Is Where the Screenless Design Pays
Both devices track sleep stages, so the difference is not the data, it is whether the device is on your wrist at 3am. A week of battery means a Fitbit Air never forces the choice between charging overnight and recording the night. An Apple Watch rated for up to 24 hours does force it, which is why Apple's 15 minute fast charge matters so much: the workable routine is to top up while you shower or eat dinner rather than overnight.
Comfort is the other half and it is genuinely subjective. A screenless pebble is smaller and has no glass against your wrist. Some people never notice an Apple Watch overnight. If you have tried and abandoned sleep tracking on a smartwatch before, that is a real signal about which of these two you will actually keep wearing.
What the Screen Buys You
During a workout the Apple Watch is not slightly better, it is a different category. Live pace, heart rate zones, intervals, music control, and third party training apps all need a display and a processor to run them. Fitbit Air detects workouts automatically and records them, which is a fair description of a background sensor, not of a training computer. If you are training for something with a target pace, the screenless option will frustrate you.
Off the run, the screen is also the notification surface, which cuts both ways. A lot of people buy a wearable for health data and end up with a second phone on their wrist. That is the actual argument for the Fitbit Air, and it is a preference rather than a spec.
Who Should Buy Which
Buy the Fitbit Air if your goal is continuous background vitals and sleep, you want to charge the thing weekly, you are price sensitive, and you will stay on the free tier. It works with both phones, requiring Android 11 or later or iOS 16.4 or later.
Buy the Apple Watch SE 3 if you have an iPhone and want notifications and live workout guidance more than you want ECG or blood oxygen. Buy the Series 12 if you want the full health set, including ECG, blood oxygen and Readiness. Buy the Ultra 4 if battery life for multi day use is the point and $799 is acceptable.
Buying both is a defensible answer that almost nobody mentions: a $99.99 band for sleep and passive vitals alongside a watch you wear for training and daily use. The cost of that combination is that your health history now lives in two apps.
Where Vora Fits
Vora is our own app, so read this as disclosure rather than a recommendation, and the routing detail below is the part worth knowing before you buy either device.
On iPhone, Vora supports Fitbit through its direct Fitbit connection only, and those direct spots are limited while Google verifies Vora's Fitbit access. On Android, Fitbit reaches Vora either directly or through Health Connect. An Apple Watch is the simpler case: it writes to Apple Health on iPhone, and Vora reads Apple Health there. So if you own an iPhone, the Fitbit Air is the device of the two that depends on getting a direct connection slot. Our integrations page lists the current status for each, and whether Fitbit Air works with Apple Health goes through the same question for Apple's own store.
One limit worth stating plainly, because it applies whichever you choose: Vora calculates its own Sleep and Recovery scores from the underlying data and does not import other companies' computed scores. Apple's Readiness score and Google Health Premium's coaching output stay in their own apps by design. What crosses over is the measurement, not the verdict.
