10 Best Smartwatch With Oximeter 2025 in the United States

The Fitbit Versa 4 Fitness Smartwatch is a strong contender in the smartwatch category, especially for those focused on health and fitness tracking. One of its standout features is the SpO2 oximeter, which allows users to monitor their blood oxygen levels effectively. This can be particularly valuable for fitness enthusiasts and those keeping an eye on their health metrics.

Battery life is impressive, lasting over six days on a single charge, which means you won't need to worry about it dying mid-workout or during sleep tracking. The display quality is decent, with a 1.58-inch touchscreen that is easy to navigate, although some may find it a bit small compared to larger models on the market.

In terms of fitness and health tracking, the Versa 4 offers a comprehensive suite of features. It includes built-in GPS, heart rate monitoring, and tracks a wide range of activities (over 40 modes). The Daily Readiness Score and personalized insights help users understand when to push harder or take a break, enhancing the fitness experience. The accuracy of the heart rate monitor can sometimes be inconsistent when compared to dedicated devices.

For compatibility, it works well with both iOS and Android devices, making it versatile. Its water resistance up to 50 meters means it can handle swimming and showers, adding to its durability.

On the design front, the Fitbit Versa 4 is comfortable to wear throughout the day, although its aesthetic may not appeal to everyone. The option to customize watch faces is a nice touch, allowing users to express their style.

As for pricing, it's competitive considering the features offered, though there are alternatives that may provide similar functionalities at a lower cost. The Fitbit Versa 4 is well-suited for fitness-focused users looking for a reliable smartwatch with robust health tracking features, but some may desire more precise metrics or a larger display.

The Apple Watch Series 9 is an impressive smartwatch that excels in several key areas. The oximeter accuracy is high, ensuring reliable health metrics. Battery life is decent for daily use, though frequent charging may be necessary for heavy users. The display quality is exceptional with an always-on Retina display and a superbright screen, making it easy to read in various lighting conditions.

Fitness and health tracking features are comprehensive, including ECG, sleep tracking, temperature sensing, and workout metrics, making it a robust companion for health-conscious users. Compatibility is limited to iPhone users, which can be a drawback for those with other smartphone brands. The design is sleek and comfortable, with the customizable pink aluminum case and sport loop adding style and comfort.

Durability is a strong point, with the watch being crack-resistant, dust-resistant, and swimproof up to 50 meters. However, the premium price may be a deterrent for some, especially when compared to other smartwatches offering similar features. The Apple Watch Series 9 is particularly suitable for users within the Apple ecosystem seeking advanced health and fitness tracking in a stylish and durable package.

The AEAC Smart Watch is a solid choice for those wanting a smartwatch with good oximeter functionality and comprehensive health tracking. It monitors blood oxygen, heart rate, stress, and sleep with helpful insights, making it useful for everyday wellness awareness. The 1.32-inch AMOLED display is bright and responsive, offering plenty of watch faces and customization options, so it looks good on your wrist. Battery life is impressive, lasting up to 10 days on a quick 2-hour charge, so you won’t need to recharge often.

It supports over 110 sports modes, covering many activities including swimming, thanks to its 3ATM water resistance, though this means it’s safe for splashes and brief immersion but not for deep-water use. The watch connects via Bluetooth to both Android (6.0+) and iOS (9.0+) devices, ensuring wide compatibility. It also features clear call quality and voice assistant support, adding convenience. The GPS depends on your smartphone, so the watch itself doesn’t have built-in GPS.

Its weight and size are quite light and slim, which is great for comfort but might not suit those wanting a more rugged feel. The interface is straightforward with touchscreen controls, making it easy to use even if you’re new to smartwatches. A 5-year warranty shows confidence in durability and customer support. For those seeking a dependable, stylish smartwatch that tracks oxygen levels and many health metrics without breaking the bank, the AEAC model is worth considering.
