10 Best Smartwatch That Works With Iphone 2025 in the United States

The Apple Watch Series 11 (46mm, GPS) is a strong choice for iPhone users who want a smartwatch that excels in health and fitness tracking. It offers advanced health features like hypertension notifications, ECG readings, blood oxygen monitoring, and even detects sleep apnea signs, making it useful if you want to keep a close eye on your wellness. Its always-on Retina display is bright and clear, and the screen is more scratch resistant than previous models, which helps with durability. Wearing comfort is high thanks to a thin, lightweight design and the included sport band.

Battery life supports up to 24 hours of regular use with fast charging, which means you can quickly boost it when needed. It’s water resistant up to 50 meters and dust resistant, so it’s safe for swimming and everyday wear. The watch connects seamlessly with your iPhone and offers helpful smart features like calls, texts, Siri, and emergency detection for falls or car crashes.

The price tends to be higher compared to many other smartwatches, but it includes a wide app ecosystem and integration that works best within Apple’s devices. The battery life, while good for a smartwatch with many sensors, might require daily charging if you use all features heavily. If you want a smartwatch that doubles as a powerful health monitor and fitness partner, and you value smooth iPhone integration with a sleek design, the Series 11 is well worth considering. However, if you’re on a tight budget or want longer battery life without daily charging, there might be simpler options to explore.

The Apple Watch Series 11 (GPS 42mm) is designed especially for iPhone users looking for a stylish, health-focused smartwatch. Its rose gold aluminum case with a light blush sport band is lightweight and comfortable for all-day wear, including during workouts and sleep. The always-on Retina display is bright and clear, with tough glass that resists scratches better than previous models.

Health tracking is a big strength here — it offers advanced features like ECG monitoring, blood oxygen readings, sleep scoring, and even hypertension and sleep apnea notifications to keep an eye on your wellbeing. Fitness tracking is comprehensive, with detailed workout metrics and helpful coaching features, plus a free trial of Apple Fitness+ to get started. Water resistance up to 50 meters means it’s swim-friendly, and it’s also dust resistant. The watch is well connected through GPS, Wi-Fi, Bluetooth, and supports emergency features like fall and crash detection.

Battery life lasts up to 24 hours with normal use, which is standard but might require daily charging; however, fast charging helps quickly top up your battery. It has a large 64GB storage for apps and music and runs the latest watchOS for a smooth app experience. Although the price is on the higher side, the device is packed with features that make it a top choice for those invested in the Apple ecosystem who want detailed health insights and a premium feel.

The Garmin vívoactive 6 is a solid choice if you're looking for a fitness-focused smartwatch that works well with an iPhone. It pairs smoothly via Bluetooth, though it uses Garmin's own operating system rather than Apple's watchOS, so app options are more limited compared to an Apple Watch. The 1.2-inch round AMOLED display is bright and clear, making it easy to see your stats and notifications even in daylight. You can enjoy up to 11 days of battery life in smartwatch mode, which means fewer charges compared to many competitors.

Health and fitness tracking is a strong point here: the vívoactive 6 offers heart rate monitoring, sleep tracking with personalized coaching, stress and energy level insights, along with more than 80 built-in sports apps including swimming and golf. It also features helpful tools like animated workouts and Garmin Coach adaptive plans to guide your training. The watch is lightweight and comfortable to wear all day, which is important for continuous health monitoring. Garmin's Body Battery feature gives useful feedback on when to push yourself or rest.

Garmin smartwatches generally handle swimming and sweat well, making this model suitable for active users. The design is sleek but may feel a bit utilitarian compared to some fashion-focused smartwatches. The price reflects its fitness-first approach, offering great value for health enthusiasts but perhaps less appeal if you want extensive third-party apps or deeper iPhone integration like Apple Pay or Siri. If your priority is detailed health data, long battery life, and a robust set of sports features, the Garmin vívoactive 6 is a dependable companion for iPhone users. For those seeking a smartwatch that also functions as a full app and smart assistant hub, the device’s ecosystem might feel more limited.
