The right choice depends on the phone you own and the exact models you compare: Fitbit devices do not all share the same features, and Apple Watch capabilities vary by generation.
Start with the phone you use
Fitbit setup guidance lists iOS 16.4 or later and Android 11 or later as requirements. Check the current requirements for your phone and intended Fitbit model before buying: Google’s Fitbit setup requirements.
Apple Watch is designed around iPhone. Confirm that the iPhone you own supports the specific watch generation you are considering; compatibility requirements can differ by model. Apple’s model comparison is a useful place to check watch differences, but verify the pairing requirement for your chosen model as well.
Decide whether you want a smartwatch or mainly a tracker
Apple Watch: fitness tracking within an iPhone-centered smartwatch
Apple Watch combines health and fitness features with communications, connectivity, and safety functions. That makes it the stronger fit if you want a device that does more than record workouts and daily activity, and you value how it works with your iPhone. Which functions you get depends on the model and generation; Apple’s comparison of Series 11 and Series 7 illustrates that differences exist even between generations.

Fitbit: choose a specific device, not an assumed family feature set
Fitbit includes both tracker-style bands and watch-style devices, and their features differ. Google’s device-by-device tracking-data documentation lists measures supported by each model. For example, its Charge 6 entry includes steps, distance, swimming, cardio fitness, a sleep log with stages and score, heart rate, and additional wellness data. Treat that as a description of Charge 6, not a guarantee about every Fitbit.
Compare the exact tracking features you care about
Make a short list of the activity, sleep, and wellness information you actually plan to use, then check the product documentation for the precise models on your shortlist. The data available varies across Fitbit devices and Apple Watch generations. Do not infer a feature from a brand name alone.

How often are you willing to charge?
Google estimates that Fitbit Charge 6 can run for up to seven days; it also estimates up to five hours when using continuous built-in GPS. Google notes that settings such as always-on display and continuous GPS reduce runtime. These are manufacturer estimates, not results from a head-to-head battery test: Google’s Fitbit battery guidance.

Apple publishes battery estimates under its own test conditions, and actual runtime varies with use and configuration. Because Apple and Google use different methodologies, their advertised figures should not be read as a directly comparable test. If charging less often is important, compare the estimate and conditions for the particular devices you are considering, then account for your own settings and habits.
