Ecosystem lock-in is real — Apple Watch only works with iPhone; Wear OS works with both platforms.
Battery life ranges from 18 hours (Apple Watch) to 21 days (Garmin) — decide how often you want to charge.
Premium health sensors (ECG, blood oxygen, skin temperature) are only on higher-tier models.
Always-on displays are useful but drain battery significantly on most platforms.

Preguntas frecuentes
Is Apple Watch worth buying with an Android phone?
No — Apple Watch requires an iPhone for setup and full features. Samsung Galaxy Watch and Google Pixel Watch are the best Android alternatives.
Are smartwatch health metrics accurate?
Heart rate and step counting are reliable. Sleep tracking is broadly accurate but not medical grade. ECG readings are directionally useful but not a substitute for clinical measurement.
