Quick Answer
Fitbit is cheaper to buy and more expensive to own; Garmin is the reverse. A Fitbit Charge 6 is $159.95 and gives you an ECG app, Google Wallet and Google Maps on your wrist — but Daily Readiness and the coaching sit behind Google Health Premium at $9.99 a month once the included three months run out. Garmin charges $299.99 for a vivoactive 6 and then charges nothing: Body Battery, sleep coach, HRV status and Training Readiness are free, and Connect+ at $6.99 a month is optional and app-side only. Battery is not close once you match the modes — Google quotes the Charge 6 at up to 7 days and up to 5 hours of continuous GPS, Garmin quotes the vivoactive 6 at up to 11 days and 21 hours of GPS-only. Buy Fitbit if you want the cheapest honest tracker and don't mind a subscription prompt. Buy Garmin if you want to buy once.

Fitbit wins the price tag and Garmin wins the receipt. That is the honest shape of this comparison, and almost every version of it you will read gets distracted by step counts and screen sizes before it gets there. The hardware gap between a $159.95 Fitbit Charge 6 and a $299.99 Garmin vivoactive 6 is real but survivable. The gap between what each brand charges you after the box is open is the thing that decides it.
We don't own either brand. We rank wearables on manufacturer specs read against each other, prices checked on the brand's own store, and what each company does and doesn't put behind a paywall — and on this matchup, the paywall is the story.

The comparison that actually decides it: what you pay after the box
Neither brand hides this, and both of them phrase it so you won't notice.
Google Health Premium is $9.99 a month. Every Fitbit ships with three months included, and when those three months end, several of the things the product pages advertise stop being yours. Daily Readiness Score — the "should I train today" number that is most of the reason to wear a tracker — is listed on Google's own Charge 6 page as "Available with Google Health Premium". The detailed breakdown behind the Stress Management Score is Premium. The whole Google Health Coach layer, the Gemini-built coaching Google is now leading its marketing with, is Premium. The device keeps tracking; the interpretation is rented.
Garmin Connect+ is $6.99 a month, and it is optional in a way Google's isn't. Garmin sells it as premium features and extra insights inside the Connect phone app. Body Battery, sleep coach, HRV status, Training Readiness, Training Status and load tracking are in the free app on the watches that support them. There is nothing on a Garmin watch that stops working if you never pay a cent beyond the purchase.
Run that forward. A Charge 6 is $159.95, plus nine months of Premium in year one at $9.99 — about $250 all in — and then $119.88 every year after that, for ever. A vivoactive 6 is $299.99 and then nothing. The two totals cross just past the seventeen-month mark, and after that the cheap tracker is the expensive one by a widening margin.
That is not an argument that Fitbit is a bad buy. It is an argument that the sticker price is not the comparison, and if you are the kind of person who cancels subscriptions and then misses the feature, you should know which brand is which before you buy.
Battery: the numbers do not mean the same thing
This is where cross-brand comparisons go wrong, and it is worth two minutes because the error always flatters the same side.
Google publishes one all-day number per device, and one GPS number. The Charge 6 is "up to 7 days", and separately "up to 5 hours" with continuous GPS. Google does not name a satellite mode, does not split the figure by case size, and does not publish a separate always-on-display number — the Charge 6 has an always-on mode, and the page says only that it "may require more frequent charging".
Garmin publishes four to seven modes per watch, per case size. The vivoactive 6 is quoted at up to 11 days in smartwatch mode with 5 days if the display stays on, 21 days in battery-saver smartwatch mode, 21 hours in GPS-only GNSS, 17 hours in all-systems GNSS, and 8 hours in all-systems with music playing.
So the honest pairs are these:
| What you're measuring | Fitbit Charge 6 | Garmin vívoactive 6 |
|---|---|---|
| All-day wear, display not forced on | Up to 7 days | Up to 11 days |
| All-day wear, display always on | Not published | Up to 5 days |
| GPS tracking, best case | Up to 5 hrs (continuous GPS) | Up to 21 hrs (GPS-only GNSS) |
| GPS tracking, more satellites | Not published | Up to 17 hrs (all-systems GNSS) |
Two things fall out of that table. The first is that the GPS gap is enormous — four to five hours against seventeen to twenty-one — and it is the gap that matters if you run, hike or cycle with the watch rather than just wearing it. The second is subtler: Fitbit's 7 days and Garmin's 11 days are both "we didn't force the screen on" figures, so they are comparable, but the moment you want an always-on display Garmin tells you it costs you six days and Google tells you nothing at all.
And Garmin's headline figure belongs to one case size. The Venu 4 is advertised at up to 12 days. That is the 45 mm. The 41 mm, at the same $549.99 starting price, is quoted at up to 10 days, and its GPS-only figure drops from 20 hours to 15. If battery is why you are buying, read the row for the size on your wrist, not the number in the headline.
The same discipline applies to Fitbit's older smartwatches. The Versa 4 and Sense 2 are both quoted at 6+ days and up to 12 hours of GPS — better GPS runtime than the Charge 6, worse than any Garmin here.
Where Fitbit genuinely wins
Garmin has the better spec sheet in almost every row above, so it is worth being precise about what Google is actually better at, because it isn't nothing.
The price floor. The Fitbit Inspire 3 is $99.95 and the Fitbit Air starts at $99.99. Garmin's cheapest current tracker is the CIRQA Smart Band at $199.99, and its cheapest small watch, the Lily 2, starts at $249.99. If your budget is a hundred dollars, Garmin does not have an answer and Google has two.
ECG at $159.95. The Charge 6 has an ECG app for assessing heart rhythm for atrial fibrillation, plus irregular heart rhythm notifications, both limited to select countries. The cheapest Garmin here with the ECG app is the Venu 4 at $549.99 — the vivoactive 6 does not have it. That is a $390 difference for the same category of feature, and if AFib screening is your reason for buying a tracker, it settles the argument on its own.
Google's own apps on the band. Google Wallet for contactless payments and Google Maps with turn-by-turn directions, on a $159.95 tracker with no screen bigger than a stick of gum. Garmin Pay exists on the vivoactive 6 and Venu 4, but you are paying $299.99 or more to get it, and Garmin has no Maps equivalent.
iPhone parity, mostly. The Charge 6, Inspire 3 and Fitbit Air all work with iOS and Android. Google's actual smartwatch, the Pixel Watch 5 at $399.99, is Android-only — so if you carry an iPhone, the Fitbit half of Google's range is the only half open to you. Every Garmin here works with both.
It is simpler. This is a real advantage and it does not show up in a table. A Fitbit gives you a step count, a sleep score and a readiness number. A Garmin gives you Body Battery, HRV status, Training Readiness, Training Status, acute load, load ratio, intensity minutes and a recovery timer, and for a lot of people that is a dashboard they will never read.
Garmin vívoactive 6 — $299.99
The watch we would hand to someone who said "I want a Fitbit but better" and didn't want a follow-up conversation.
Pros
- Up to 11 days in smartwatch mode, 5 days with the display always on, 21 days in battery saver
- 21 hours of GPS-only GNSS, 17 hours all-systems, 8 hours all-systems with music
- Body Battery, sleep coach, HRV status and Training Readiness, all in the free Garmin Connect app
- Garmin Pay contactless payments and onboard music storage
- 42.2 mm AMOLED, 10.9 mm thick, built-in GPS
- More than 80 preloaded sports apps
Cons
- No ECG app — that is a Venu 4 feature at $549.99
- No LED flashlight, which the Venu 4 and Forerunner 70's siblings have
- Nearly double a Charge 6 up front, and it looks like a watch rather than a band
- One case size only, so there is no smaller option for a narrow wrist
What you notice that the spec sheet won't tell you: Garmin publishes battery for five distinct modes on this watch and gives you the always-on-display penalty as its own number. Google, on a product in the same category at half the price, publishes two figures and a sentence saying always-on "may require more frequent charging". Neither brand is lying. Only one is letting you plan.
Best for: anyone who wants Fitbit-style daily health tracking without a monthly bill attached to it.
Fitbit Charge 6 — $159.95
The best tracker under $200 on either side of this comparison, with one asterisk you have to price in.
Pros
- $159.95 with an AMOLED display, built-in GPS and a 5 ATM water rating
- ECG app and irregular heart rhythm notifications for AFib, in select countries
- EDA scan for stress response, SpO2, skin temperature variation, sleep stages and Sleep Score
- Google Maps turn-by-turn and Google Wallet payments on the wrist
- Broadcasts heart rate to compatible gym equipment
- Works with iOS and Android
- Up to 7 days of battery
Cons
- Up to 5 hours with continuous GPS — the shortest GPS runtime of anything here
- Daily Readiness Score and the detailed stress breakdown need Google Health Premium at $9.99/month after the included three
- No always-on-display battery figure published, so you are guessing what that mode costs you
- Bluetooth notifications only; no third-party app layer
What you notice that the spec sheet won't tell you: the Charge 6 carries an ECG app at $159.95, and the cheapest Garmin in this comparison that does is the Venu 4 at $549.99. Google buried it in a features list two-thirds down the page; Garmin puts ECG in its flagship health watch and prices it accordingly. If you want heart-rhythm screening on a budget, Fitbit is not the compromise here, it is the answer.
Best for: budget buyers who want a real tracker with real health features and will either pay for Premium or genuinely not miss it.
Garmin CIRQA Smart Band — $199.99
Garmin's screenless band, announced 21 July 2026, and the most direct answer to the Fitbit Air that exists.
Pros
- Up to 10 days of battery, three days more than the Fitbit Air
- No subscription required, stated on the product page rather than buried
- Body Battery, sleep coach, HRV status and Training Readiness — the full Garmin metric set, free
- Screenless, so nothing to look at and nothing to charge nightly
- Two band sizes: S-M fits 120–200 mm wrists, L-XL fits 145–240 mm
- Automatically detects a range of activities
Cons
- $199.99 against the Fitbit Air's $99.99 — twice the price for the same basic proposition
- No screen means no notifications, no payments and no time of day on your wrist
- Newer than the Air by two months, so the long-term software story is unwritten on both
What you notice that the spec sheet won't tell you: Garmin's press release led on "no subscription required" in the subtitle, which is not a phrase a company uses about its own product unless it is aiming at a competitor's. The Fitbit Air is $100 cheaper and pushes you toward $9.99 a month; the CIRQA is $100 more and pushes you nowhere. Two years of ownership is the point at which those two sentences swap places.
Best for: people who want 24/7 tracking without a screen in their life and without a recurring charge.
Garmin Forerunner 70 — $249.99
The cheapest Garmin that takes running seriously, and the direct answer to anyone who outgrew a Fitbit.
Pros
- Up to 13 days in smartwatch mode, 5 days always-on, 28 days in battery saver
- 23 hours of GPS-only GNSS and 16 hours of all-systems — more than four times any Fitbit here
- 43 mm AMOLED display
- Body Battery and Garmin's running metrics at the entry price
- Six colourways
Cons
- $90 more than a Charge 6 and it is a running watch, not a lifestyle band
- No triathlon mode, and it sits below Garmin's load and training-status tiers
- No built-in maps at this price
What you notice that the spec sheet won't tell you: its 13-day smartwatch figure is longer than the $549.99 Venu 4's on either case size. Garmin's battery numbers do not scale with price, they scale with how much display and sensor the watch has to feed, and the entry-level runner is one of the longest-lasting watches the company sells. If you buy on battery alone, you often want the cheaper Garmin.
Best for: someone who started on a Fitbit, started running properly, and wants the first watch that will keep up.
Garmin Venu 4 — from $549.99
Garmin's health flagship, and the model that shows what the brand does when it stops holding back.
Pros
- ECG app, Garmin Pay, onboard music, LED flashlight, speaker and microphone for calls
- Two case sizes, 41 mm and 45 mm, in metal
- 45 mm: up to 12 days smartwatch, 20 hrs GPS-only, 19 hrs all-systems, 17 hrs multi-band
- Body Battery, sleep coach, HRV status, women's health tracking with skin temperature
- Garmin Fitness Coach plans that adjust to your activity history, sleep and recovery
Cons
- $549.99 is three and a half Fitbit Charge 6s
- The 41 mm has a materially shorter battery than the 45 mm at the same starting price — 10 days and 15 hrs GPS-only
- Always-on display costs you two-thirds of the headline figure: 4 days on the 45 mm, 3 on the 41 mm
- Overkill if what you wanted was a step counter with a good sleep score
What you notice that the spec sheet won't tell you: this is the per-case-size trap in its purest form. Garmin's own description for the Venu 4 says "up to 12 days of battery life", and that sentence is attached to both sizes on the same product family page. It is true of the 45 mm. Buy the 41 mm and you have a 10-day watch that cost the same. Check the size before the price.
Best for: buyers who want Fitbit's health-first framing with Garmin's battery and no subscription, and have the budget for it.
Google Fitbit Air — from $99.99
Google's screenless band, launched 26 May 2026, and the cheapest way into either ecosystem.
Pros
- From $99.99 — half of Garmin's screenless equivalent
- 34.9 x 17 x 8.3 mm and light enough to forget, which is the entire point of a screenless band
- Up to 7 days of battery
- Tracks heart rate, HRV, SpO2, breathing rate, skin temperature variation, resting heart rate, steps, distance, calories and Active Zone Minutes
- Works with iOS 16.4 and Android 11 or newer
- Special Edition bands, including a Stephen Curry collection and a Pokémon Sleep edition
Cons
- The coaching, adaptive plans and detailed sleep insights are Google Health Premium at $9.99/month after three included
- Three days less battery than the CIRQA at half the price — which is the trade, stated plainly
- Screenless means no time, no notifications, no payments
- Bluetooth only
What you notice that the spec sheet won't tell you: Google's own comparison table on the Google Store puts the Fitbit Air next to the Pixel Watch 5 and the Charge 6 and marks it "Designed for Google Health — adaptive coaching, built with Gemini". That coaching is the Premium product. The band is the cheapest thing Google sells and the one most designed to sell you the subscription, and those two facts are the same fact.
Best for: someone who wants continuous tracking for a hundred dollars and is clear-eyed about the upsell.
Fitbit Inspire 3 — $99.95
The floor of the category, and still a real product.
Pros
- $99.95 with a colour touchscreen
- Up to 10 days of battery — three more than the Charge 6 above it
- SpO2, skin temperature variation, Sleep Score, Stress Management Score, Cardio Fitness Score, menstrual health tracking
- Small and light enough for a narrow wrist, where the Garmin range mostly isn't
Cons
- Connected GPS only — it uses your phone's GPS, so your phone has to come with you
- No ECG, no payments, no Google Maps
- Same Premium dependency as everything else in the Fitbit line
- The oldest hardware here by some distance
What you notice that the spec sheet won't tell you: it outlasts the Charge 6 by three days, because it has less display and fewer sensors to feed. That is the same pattern as the Forerunner 70 beating the Venu 4 on the Garmin side. In trackers, the cheap model very often wins the battery row, and both brands are quiet about it.
Best for: a first tracker, a gift, or a second band for someone who mostly wants step and sleep counts.
How to choose between them
You want the best value over two years, not two weeks. Garmin vívoactive 6, $299.99. It costs more once and never again, and the free app covers what Fitbit charges $9.99 a month for.
Your budget is under $200 and that's firm. Fitbit Charge 6, $159.95. Built-in GPS, ECG, Wallet, Maps, and a 5 ATM rating. Nothing Garmin sells at that price is close on features.
You want a screenless band. Fitbit Air at $99.99 if the price decides it, Garmin CIRQA at $199.99 if the subscription does. Ten days against seven, and no upsell against a permanent one.
You've started running seriously. Garmin Forerunner 70, $249.99. Twenty-three hours of GPS-only against the Charge 6's five is not a preference, it is a different class of product. If you have outgrown even that, our COROS vs Garmin comparison covers the tier above.
AFib screening is the reason you're buying. Fitbit Charge 6 at $159.95 or Garmin Venu 4 at $549.99. Those are the two ECG watches here, and the gap between them is $390.
You're comparing against a WHOOP or an Apple Watch too. Read WHOOP vs Fitbit and WHOOP vs Garmin — the subscription maths changes shape again when WHOOP is in the room, because there the hardware is the free part.
FAQ
Is Garmin better than Fitbit?
For battery, GPS and cost of ownership, clearly. Garmin quotes the $299.99 vivoactive 6 at up to 11 days in smartwatch mode and 21 hours of GPS-only GNSS, against Google's up to 7 days and up to 5 hours of continuous GPS on the $159.95 Charge 6, and Garmin's Body Battery, sleep coach, HRV status and Training Readiness are free where Fitbit's Daily Readiness Score and coaching need Google Health Premium at $9.99 a month. Fitbit is better on entry price — $99.95 for an Inspire 3 against $199.99 for Garmin's cheapest tracker — and on getting an ECG app onto a cheap device. Pick Fitbit for the lowest sticker price, Garmin for the lowest total.
Does Fitbit require a subscription?
Not to track. The devices record steps, heart rate, sleep, SpO2 and skin temperature with no payment. But Google lists Daily Readiness Score as available with Google Health Premium, puts the detailed Stress Management Score breakdown behind it, and the whole Google Health Coach layer is a Premium feature. Every Fitbit includes three months, then it renews at $9.99 a month. So the subscription is optional in the same sense that the interesting half of the product is optional.
Does Garmin require a subscription?
No. Garmin sells Connect+ at $6.99 a month, but it adds app-side premium features and insights — no hardware capability on the watch depends on it. Body Battery, sleep coach, HRV status, Training Readiness and Training Status are in the free Garmin Connect app on the watches that support them.
Which has better battery life, Fitbit or Garmin?
Garmin, on every honest comparison. All-day wear without forcing the display on: 11 days on the vivoactive 6, 13 on the Forerunner 70, 12 on the 45 mm Venu 4, against 7 days on the Charge 6 and Fitbit Air and 10 on the Inspire 3. With GPS running: 21 hours GPS-only on the vivoactive 6 and 23 on the Forerunner 70, against up to 5 hours of continuous GPS on the Charge 6 and up to 12 on the Versa 4 and Sense 2. The one caution is to compare mode to mode — Garmin publishes several named GNSS modes per watch and a separate always-on-display figure, Google publishes one all-day number and one GPS number and no always-on figure at all.
Can a Fitbit do ECG?
Yes, on the Charge 6. Its ECG app assesses heart rhythm for atrial fibrillation and it also gives irregular heart rhythm notifications, both available in select countries only. That is genuinely notable at $159.95, because the cheapest Garmin in this comparison with an ECG app is the Venu 4 at $549.99 — the $299.99 vivoactive 6 does not have one.
Do Fitbit and Garmin both work with an iPhone?
The Fitbit devices do — the Charge 6, Inspire 3 and Fitbit Air all list iOS and Android compatibility — and so does every Garmin watch here. Google's actual smartwatch is the exception: the Pixel Watch 5 at $399.99 is listed as Android only. So if you are on iPhone and want a Google wearable, the Fitbit line is the whole of your choice.
Is the Fitbit Charge 6 or the Garmin vívoactive 6 better?
They are not really the same product. The Charge 6 is a $159.95 band with an ECG app, Google Wallet, Google Maps and 7 days of battery. The vivoactive 6 is a $299.99 42 mm watch with 11 days, four times the GPS runtime, Garmin Pay, onboard music, 80-plus sports apps and no subscription attached to any of it. If the $140 difference is real money to you, the Charge 6 does more per dollar today. If you keep trackers for two years or more, the vivoactive 6 is cheaper by the end and better throughout.
Is the Garmin CIRQA worth twice the price of the Fitbit Air?
It depends entirely on how you feel about subscriptions. The CIRQA is $199.99 with up to 10 days of battery and Garmin's full metric set — Body Battery, sleep coach, HRV status, Training Readiness — with no subscription required. The Fitbit Air is $99.99 with up to 7 days, and its adaptive coaching and detailed sleep insights are Google Health Premium at $9.99 a month after the three included. Pay Garmin the extra $100 once and, counting the Air's three free months, the two of them cost the same at about thirteen months in. Everything after that is Garmin's.
Are the Fitbit Versa 4 and Sense 2 still worth buying?
Only on a deep discount. Google still sells both — the Versa 4 at $199.95 and the Sense 2 at $249.95 — and both are quoted at 6+ days of battery and up to 12 hours of GPS, which is better GPS runtime than the Charge 6 but well short of anything Garmin sells here. Neither appears in Google's own three-way comparison on the Google Store, which shows the Pixel Watch 5, the Fitbit Air and the Charge 6. When a company leaves two products out of its own buying guide, take the hint.
Our Verdict
If we were spending our own money on one tracker today, it would be the Garmin vívoactive 6 at $299.99. Eleven days of battery, 21 hours of GPS, Garmin Pay, onboard music, and a complete set of health metrics with nothing rented. The Fitbit that competes with it on features costs $549.99 in Garmin's own range and $159.95 plus $9.99 a month in Google's, and the second of those only stays cheap if you never want the readiness score.
The Fitbit Charge 6 at $159.95 is still the right answer for a real set of buyers, and we would not talk anyone out of it. Built-in GPS, an ECG app, Google Maps and Google Wallet, iOS and Android, for a third less than the Garmin. Buy it knowing that the subscription prompt arrives in month four and that five hours of GPS is a weekend hike, not a week of them.
The buy we would argue hardest against is the Garmin Venu 4 at $549.99 in its 41 mm size. Same price as the 45 mm, two fewer days of battery, five fewer hours of GPS. If you want that watch, want it in 45 mm, or take the vívoactive 6 instead and put the $250 somewhere it does something.
