About Apple Watch
Apple Watch is a line of smartwatches designed and sold by Apple Inc., first released in April 2015. It is the world's best-selling wearable device and holds approximately 35% of the global smartwatch market. The Apple Watch Ultra 2, Series 10, and SE make up the current lineup, ranging from $249 to $799. Apple Watch integrates deeply with iPhone, offering notifications, Siri, Apple Pay, and App Store access. Its health and fitness features are central to its appeal: ECG heart monitoring (detecting atrial fibrillation), blood oxygen (SpO2) measurement, sleep tracking, fall detection, crash detection, and FDA-cleared irregular heart rhythm notifications. The watch uses watchOS, updated annually, and typically receives software support for 4-5 years after release. Apple Watch Series 4 and later earned FDA clearance as a medical device for ECG capabilities. The Apple Watch Ultra series (introduced in 2022) targets extreme athletes with titanium casing, 36-hour battery life, and dual-frequency GPS. Worldwide, Apple sells approximately 40-50 million watches annually, generating estimated revenue of $20-25 billion per year.
Frequently Asked Questions
Does Apple Watch work with Android?
No — Apple Watch requires an iPhone (iPhone XS or later, iOS 17 or later). It does not function as a standalone smartwatch with Android phones. Android users should consider Samsung Galaxy Watch, Garmin, or Fitbit instead.
Apple Watch vs Fitbit: which is better?
Apple Watch is better for iPhone users who want a comprehensive smartwatch with apps, Apple Pay, and deep health monitoring. Fitbit is better for users prioritizing battery life (5-7 days vs 18-36 hours), cross-platform compatibility, and simpler fitness tracking at a lower price. For Android users, Fitbit is the clear choice as Apple Watch doesn't work at all.
How accurate is Apple Watch heart rate?
Apple Watch's optical heart rate sensor is clinically validated and accurate within ±5% during resting and moderate activity. For high-intensity exercise, accuracy can degrade compared to a chest strap. The ECG feature is FDA-cleared for detecting atrial fibrillation and is considered medical-grade for that specific purpose.
