Apple Watch 對比 Fitbit：哪一個更適合你？

For everyday metrics like steps, heart rate, and sleep stages, both are good and the gap is small. Apple Watch carries more advanced sensors, including an ECG and, on supported models, blood oxygen, and its workout heart-rate tracking is strong. Fitbit is well regarded for sleep tracking and all-day resting heart rate. The bigger accuracy question is usually not the device but what you do with the readings: a number is only useful if something reads it in context.

Yes. Fitbit works with both iPhone and Android through the Fitbit app, which is one of its main advantages over Apple Watch. Apple Watch requires an iPhone and does not pair with Android at all. So if you might switch phones, or you are on Android today, Fitbit keeps your options open in a way Apple Watch cannot.

Fitbit, comfortably. Most Fitbit trackers run for several days to about a week on a charge, while a standard Apple Watch is typically a daily or every-other-day charge (the Ultra line lasts longer). If you want to wear it overnight for sleep without juggling charging, Fitbit makes that easier. Apple Watch trades battery for being a far more capable wrist computer.

Core tracking on both is usable without paying. Apple keeps most health features free on the device, with Fitness+ as an optional workout-content subscription. Fitbit puts some of its deeper insights, including parts of Daily Readiness and advanced analytics, behind Fitbit Premium. Check which specific features you care about before you buy, because the free experience is not identical between them.

Yes. Wellness Project connects to Fitbit directly, and it reads Apple Watch data through Apple Health on iPhone. So steps, heart rate, sleep, and workouts from either device flow into one history that the AI coaches read together. That is the point of this comparison: the device you strap on matters less when the analysis layer works with whichever one you choose.
