Apple Health 對比 Google Health Connect

Apple Health is the built-in health database on iPhone. It collects readings from Apple Watch and from third-party apps and keeps them in one place on your device. Google Health Connect is the equivalent hub on Android: an on-device store that lets your health and fitness apps read and write the same data, so a workout logged in one app can show up in another. Both solve the same problem, fragmented health data, but each lives on its own platform.

Neither is better in the abstract, because you do not really choose between them; your phone does. Apple Health is the hub on iPhone, Health Connect is the hub on Android, and each is the standard place apps share data on its own platform. What decides how useful your data is comes after the hub: whether something reads across everything it collects. Wellness Project reads both, so the answer does not change when you switch phones.

There is no official one-tap transfer between the two, because they live on different operating systems. If you switch phones, the practical approach is to reconnect your devices and apps on the new platform and let the data flow forward from there. Our guide on syncing Google Health to Apple Health walks through the realistic options. The good news is that a tool reading from both means your history is not stranded when you move.

Both are designed around on-device storage and per-app permission prompts, so you control which apps can read which data types. Neither is a cloud profile that apps query freely; each asks you to grant access category by category. The privacy posture is broadly similar. The thing to watch is not the hub itself but which apps you grant access to and what those apps do with the data once they have it.

Yes. Wellness Project reads Apple Health on iPhone and Google Health Connect on Android, so steps, sleep, heart rate, and workouts reach the same unified record regardless of platform. That means the AI coaches see your data the same way whether you are on iOS or Android, and switching phones does not cost you the coaching.
