Whether you’re swimming laps, running in the rain, or simply sweating through an intense workout, you need a fitness tracker that can handle moisture without missing a beat.
In 2025, waterproof fitness trackers have evolved far beyond basic step counting — offering advanced heart rate monitoring, GPS tracking, swim stroke recognition, and even open-water swim data.
In this guide, we’ll explore the best waterproof fitness trackers of 2025, breaking down their key features, pros and cons, and ideal use cases.

- Swim Tracking: Count laps, strokes, and calories burned in the pool.
- Durability: Withstands rain, sweat, and accidental spills.
- All-Day Wear: No need to remove it for showers or workouts.
