It just works with my iPhone
Notifications, workouts, Apple Pay, and health all sync flawlessly. The bigger screen is easy to read on a run.

Wish it lasted longer
Love the watch but I charge it every night. For sleep tracking I top it up while showering. Everything else is excellent.

From the community
QIs blood oxygen available?
Availability varies by region due to legal restrictions; ECG and heart rate are widely available worldwide.
QWhich size should I get?
The larger 46mm case is easier to read and fits most wrists; the 42mm suits smaller wrists and lower-profile wear.
Frequently asked
Does it work with Android?
No — the Apple Watch requires an iPhone. Android users should consider the Galaxy Watch 7 or Pixel Watch 3.
How long does the battery last?
About 18 hours of typical use, or up to ~36 hours in Low Power Mode. Fast charging makes daily top-ups quick.
Can it track sleep accurately?
Yes — it tracks sleep stages and respiratory rate, though multi-day Garmin and Galaxy watches are easier to wear overnight without charging anxiety.
