10 Best Iphone Compatible Smart Watches 2025 in the United States

The Apple Watch SE 3 (40mm, GPS) is a solid choice if you want a smartwatch that works smoothly with an iPhone. It has a sharp and bright Always-On Retina display, so you can easily see the time and notifications without lifting your wrist. The battery lasts through a full day (about 18 hours) and charges quickly, which is handy if you need a fast top-up. For fitness and health, it offers a wide range of tracking features including heart rate monitoring, sleep analysis with a daily sleep score, temperature sensing, and even alerts for unusual heart rhythms. It also has safety tools like fall detection and crash detection that can automatically call for help if needed, which adds peace of mind. The watch is water resistant, so you can wear it while swimming or in the rain without worry.

Staying connected is simple with texting, calls, music, and Siri voice assistant—all working through your iPhone or Wi-Fi. It also supports Apple Watch for Kids, letting family members stay in touch even without their own iPhones. On the design side, it’s lightweight and comfortable with customizable watch faces and bands, making it easy to match your style. However, since this is the GPS-only model, it needs to be near your iPhone or Wi-Fi for full connectivity and can’t make cellular calls independently. Also, the battery life isn’t the longest compared to some competitors, especially if you use many features.

The price might be higher than basic fitness bands, but you get a lot of useful health, safety, and smart features packed into a sleek, user-friendly device. It makes a great pick if you want a reliable Apple smartwatch experience without the extra cost of cellular models.

The Garmin Venu 3S Smartwatch is a strong contender in the iPhone-compatible smartwatch category, boasting several notable features. Its 1.2-inch AMOLED touchscreen display is vibrant and colorful, making it easy to read in various lighting conditions. The battery life is impressive, lasting up to 10 days in smartwatch mode, which is excellent for users who prefer not to charge their watch frequently.

The fitness tracking capabilities are extensive, including unique features like Body Battery energy monitoring and wheelchair-mode tracking, making it a great choice for health-conscious individuals and those with specific accessibility needs. The watch also offers advanced health monitoring, including sleep score, personalized sleep coaching, wrist-based heart rate monitoring, and more.

The Garmin Venu 3S supports Bluetooth and Wi-Fi connectivity, allowing for seamless integration with your iPhone. You can make and take phone calls directly from the watch and use your smartphone’s voice assistant for responding to texts. The design features a sleek Silver Stainless Steel Bezel and a comfortable silicone band, available in an attractive Sage Gray color. However, the Garmin OS may not offer as wide a range of apps as other platforms like Apple’s WatchOS. Additionally, while the smartwatch supports music downloads from popular services like Spotify, a premium subscription is required. The Garmin Venu 3S is a well-rounded smartwatch with excellent battery life, comprehensive fitness tracking, and useful health monitoring features, though it may be limited in app availability compared to other smartwatches.

The AEAC Smartwatch for Women is designed to be a versatile companion for iPhone users, but also compatible with Samsung and Android devices. Its compatibility with multiple operating systems makes it a flexible choice for many users. The smartwatch boasts a 1.32-inch AMOLED touchscreen that offers sharp visuals, enhancing user experience with clear display quality and customizable watch faces.

Additionally, the watch supports an impressive 110+ sports modes, catering to a wide range of activities, and is water-resistant up to 3ATM, making it suitable for swimming and other water activities.

A long-lasting battery life, up to 10 days per charge, ensures the watch remains functional throughout extended use without frequent recharging. Connectivity is managed via Bluetooth, allowing seamless integration with your smartphone for calls and notifications; however, it relies on the phone's GPS for location tracking, which might be a limitation for some users expecting built-in GPS functionality. The design is lightweight and comfortable, weighing only 5 grams, and provides an elegant appearance with a round shape. Although the smartwatch offers many features, the memory storage capacity and RAM size are relatively modest, which might limit the performance of certain apps or features.
