10 Best Waterproof Fitness Trackers 2026 in the United States

The Apple Watch Series 11 is a highly capable waterproof fitness tracker designed to support a wide range of health and fitness needs. It is water resistant up to 50 meters, making it suitable for swimming and other water sports, which is great if you want a device that can handle wet conditions. Its battery lasts up to 24 hours with normal use, which means you’ll likely need to charge it daily, but it offers fast charging to quickly regain power when needed. The watch provides advanced activity tracking features like heart rate zones, sleep scoring, and workout metrics, plus important health monitoring such as ECG, blood oxygen, and even alerts for hypertension and irregular heart rhythms. This makes it especially useful if you want detailed insight into your health rather than just basic step counting.

Built-in GPS enables accurate location tracking for outdoor activities without relying on your phone. The always-on Retina display is bright, sharp, and easy to read, while the interface is smooth and integrates well with the iPhone and Apple’s fitness apps. The watch is best suited for iPhone users due to its ecosystem reliance, and it might be more complex than needed if you want a simpler tracker. Additionally, its premium features come with a higher price tag compared to basic fitness bands.

If you want a stylish, durable, and feature-rich waterproof smartwatch that covers everything from serious health monitoring to everyday fitness tracking, the Apple Watch Series 11 is a strong choice.

The Oura Ring 4 is a smart ring designed for health and activity tracking with a strong focus on sleep, women’s health, and stress management. Its water resistance up to 100 meters makes it suitable for swimming and everyday water exposure, a solid feature for a waterproof fitness tracker. The battery life of up to 8 days is impressive, meaning you won't need frequent charges, and the ring charges fully in about 80 minutes.

While it tracks over 50 health metrics—including body temperature, menstrual cycle, and heart health—it does not have a display, so all data is accessed through its smartphone app, compatible with both Android and iOS. GPS functionality depends on your smartphone's GPS, as the ring itself doesn’t have built-in GPS, which may affect standalone use for some outdoor activities. The ring is lightweight and made from durable titanium, lending to comfort and style, though sizing is unique and requires a special kit to ensure the right fit. A subscription to the Oura membership is needed for deeper insights after the first free month, which may be a downside for some users.

This ring is ideal for those prioritizing detailed health monitoring and sleep insights rather than a traditional fitness tracker with a real-time display and built-in GPS. It offers a discreet, stylish option for users who want to track a broad range of wellness metrics while benefiting from good battery life and waterproof protection.

The Oura Ring 4 is a sleek, compact fitness tracker designed as a ring, making it an excellent option for those who prefer a less bulky wearable. It offers excellent water resistance with an IP68 rating and can be submerged up to 100 meters, making it well suited for swimming and everyday water exposure. The battery life is impressive, lasting up to 8 days on a single charge, which reduces the need for frequent recharging. However, it does not include built-in GPS, so detailed route tracking for runs or bike rides is not available.

One of Oura's biggest strengths is its comprehensive health tracking capabilities. It monitors over 50 metrics including sleep patterns, activity levels, stress, heart health, body temperature, and women's health such as menstrual cycles. The ring uses Smart Sensing technology to deliver continuous and accurate data without requiring a display on the device itself. This means it has no screen or vibrations on the finger, which some may find more comfortable, but it also requires checking the smartphone app frequently to view your stats.

The Oura app is compatible with both Android and iOS devices, offering detailed insights and personalized recommendations through a subscription membership (first month free). While it supports Bluetooth syncing, the absence of GPS and display limits direct on-the-go feedback compared to many waterproof wrist fitness trackers. The Oura Ring 4 suits users who want a stylish, waterproof wearable focused on detailed health and sleep tracking with long battery life, without the bulk of a wristband or the need for GPS.
