Samsung Galaxy Watch vs Apple Watch：哪一款適合你？

No. Current Galaxy Watch models run Wear OS and pair with Android phones only; they no longer support the iPhone. The Apple Watch is the mirror image, requiring an iPhone and not pairing with Android. For most people this single fact decides the comparison: you buy the watch that matches the phone you already carry, and the rest of the differences become secondary.

Both are strong, full-featured smartwatches with heart rate, sleep tracking, and an ECG on supported models, plus broad workout tracking. The Galaxy Watch adds body-composition measurement on supported models, though some of its most advanced features work best, or only, when paired with a Samsung phone. The Apple Watch leans on a very deep app ecosystem and tight iPhone integration. The honest answer is that the bigger difference is the phone, not the sensors.

The Galaxy Watch logs into the Samsung Health app on Android, while the Apple Watch feeds into Apple Health on iPhone. Both are capable hubs, but they are separate islands tied to their platforms, and neither talks to the other directly. That is one reason it helps to have an analysis layer that can read whichever ecosystem you land in rather than locking you to one app.

Both are in the same general class, roughly a daily-to-two-day charge depending on the model and settings, with larger or rugged variants lasting longer. Neither is a multi-day device the way a ring or a simple band can be, so plan on charging regularly if you wear it overnight for sleep. If long battery without charging is your priority, a smartwatch in either family is not the category to optimize for.

Yes, through different paths. Wellness Project reads Apple Watch data directly through Apple Health on iPhone. The Galaxy Watch reaches it on Android: Samsung Health syncs to Android Health Connect, and Wellness Project connects to Health Connect, so your Galaxy Watch data flows in that way. Either route lands your steps, heart rate, sleep, and workouts in one history that the AI coaches read together, which is the point of this comparison.
