Choose based on your phone and whether you want a smartwatch or a focused fitness tracker. Apple Watch is the more natural fit for an iPhone owner who wants smartwatch, health and connectivity features; Fitbit Charge 6 is worth considering if you want a tracker that works with most newer Android and iOS phones and a longer stated battery life. Those are model-specific trade-offs, not a universal brand winner.
Start with phone compatibility
Compatibility can rule out an option before you compare features. Apple says its current Apple Watch SE 3, Series 11 and Ultra 3 require an iPhone 11 or later running iOS 26 or later. Google says Fitbit Charge 6 works with most phones running Android 9 or later or iOS 15 or later, and requires a Google Account and internet access. Check the requirements for the exact model and your region before buying: Apple’s current-model announcement and Google’s Charge 6 announcement describe these requirements.

Charge 6’s broader phone support does not make every Fitbit feature identical across phones. For example, Google says YouTube Music controls require a compatible phone nearby and a paid YouTube Music Premium subscription.
Decide whether you want a smartwatch or a tracker
Apple Watch: a wrist-worn extension of iPhone
Apple positions the SE 3 as its value option, Series 11 as the broad health-feature choice, and Ultra 3 as an adventure-oriented watch. The models differ, so do not assume that a feature on one Apple Watch is available on another. Apple’s model comparison lays out differences among these watches.

Fitbit: compare the device, not just the brand
Charge 6 is a fitness tracker with built-in GPS and select Google integrations, including Maps and Wallet. Google’s comparison page also lists devices such as Sense 2 and Versa 4, but that does not mean they share Charge 6’s features or requirements. Compare the exact Fitbit model with the Apple Watch you are considering; Google’s Fitbit and Google smartwatch comparison provides model-level comparisons.
Compare the specific features you will use
For activity and everyday wear, consider the device’s size, the sports you do, whether you need built-in GPS, and its water-use limits. Apple documents different water limits by model, and says water resistance is not permanent. No independent comfort comparison is established here, so fit and comfort are best treated as personal considerations rather than a reason to assume one brand will feel better.

Health features also depend on model, age, region and software. Apple says the ECG app is available on Series 4 and later except SE models, and describes it as similar to a single-lead ECG. Apple lists sleep apnea notifications for Series 9 and later, Ultra 2 and later, and SE 3 for adults 18 or older without a diagnosis. Apple also labels some measurements and Vitals as intended for wellness, not medical use. These functions are not a substitute for medical diagnosis or treatment; see Apple’s feature and eligibility notes.

Google says Charge 6 offers up to seven days of battery life. Apple’s January 2026 announcement gives Ultra 3 a 42-hour battery life and says Series 11 lasts longer than its predecessor. These are manufacturer claims, not results from a like-for-like independent test; they do not establish which brand lasts longer under the same use. The number you experience can depend on how you use the device. Sources: Google/Fitbit on Charge 6 and Apple on its current models.

Which one should you choose?
- Choose Apple Watch if you have a compatible iPhone and want the smartwatch and health features of a specific Apple model. Match the model to the features you need, rather than assuming the lower-cost SE has every feature found on Series or Ultra.
- Consider Fitbit Charge 6 if you want a fitness tracker that Google says works with most newer Android and iOS phones, and its Google integrations and stated battery estimate suit your needs.
- Compare named devices if you are considering a Fitbit smartwatch-shaped model such as Sense 2 or Versa 4. The Fitbit name alone does not tell you which functions, compatibility or battery claims apply.
Neither the cited official materials nor the listed comparison pages establish an independent winner for heart-rate, GPS, sleep or workout accuracy. Treat accuracy rankings you encounter elsewhere as a separate claim that needs a specific test and methodology.
