Best Android Smartwatch for Fitness: Waterproof Trackers

Hi friends! 👋 I’m Marry. Over the last few years, I’ve tested many smartwatches — from low-cost trackers to top brands built like tanks.

When I first started running, I didn’t care about tracking my workouts. But after missing my goals again and again, I knew I needed help. My phone app was way off. So, I got my first smartwatch. And wow — that changed everything.

If you’re searching for the Best Android Smartwatch for Fitness, this guide is for you.

Maybe you want a waterproof fitness tracker for swimming. Or a Bluetooth calling smartwatch for workouts. Or maybe you need one with Alexa built-in to stay connected hands-free.

I’ve tested, compared, and ranked the top models for 2025. I’ll also share my real experiences, small wins, and lessons.

Let’s get started.

🧭 How I Test Smartwatches

I always test smartwatches the same way, so results are fair and real.

• Battery Test: I charge each watch fully. I keep brightness at 60%, and all alerts on. Then I time how long it lasts during workouts and sleep.
• Heart Rate Test: I compare the watch to my Polar H10 chest strap. It’s a pro-level sensor, so I can see how close the readings are.
• Waterproof Test: I wear IP68 watches in a pool for 30 minutes. Then I check if the screen, sensors, and buttons still work.
• Comfort Test: I wear each watch all day — while I work, cook, shower, and sleep.
• App Check: I test how well the watch pairs with Android (Samsung S24 Ultra) and iPhone 15.

🌟 Why a Fitness Smartwatch Matters

A fitness smartwatch is more than a step counter. It’s a small health coach on your wrist.

When I started tracking sleep, I realized I was only sleeping 6 hours — not 8. My sleep and stress monitoring watch showed how tired I was. Fixing my bedtime gave me more energy, better focus, and even faster runs.

Today’s watches do so much more. They:

• Track heart rate all day.
• Check SpO₂ for oxygen levels.
• Help manage stress.
• Work under water and rain.
• Let you answer calls or read messages.
• Even talk back — thanks to Alexa and voice assistants.

Let’s look at the best models that make fitness fun and easy.
