Healthy’s Summary
Looking for the best medical-grade smartwatch in 2025 to help track your heart, sleep, and maybe even your stress? You’ve got more options—and more accuracy—than ever before.
Forget basic step counters. Today’s top health wearables go way beyond counting steps or buzzing you for texts.

All designed to help you (and your doctor) get a better picture of your health, in real time.
Whether you’re managing a heart condition, curious about your sleep cycles, or just into data-driven wellness, here are five smartwatches that are truly raising the bar in 2025.
What’s the best medical-grade smartwatch for health tracking in 2025?
Smart watches aren’t just a popular consumer electronic toy – their becoming more and more medically relevant. Millions of people are already using smartwatches for daily and even hourly tracking for a wide range of health and wellness measurements. Everything from heart rate and oxygen levels to calorie burn and sleep. The National Institutes of Health published the results of a recent study that found smart watches to be effective at diagnosing a variety of diseases, including heart and movement disorders.

1. Apple Watch Series X (FDA-Cleared ECG + Afib Alerts)
Apple’s latest release is still leading the pack when it comes to heart health. The Series X offers:
- FDA-cleared ECG
- Real-time Afib detection
- VO2 max, SpO₂, and heart rate variability (HRV)
- Sleep stages with breathing and movement tracking
- A new skin temperature sensor for menstrual health & fever detection
It’s sleek, reliable, and deeply integrated with iPhone—but it still doesn’t work with Android, which might be a dealbreaker.
2. Withings ScanWatch 2 (European Precision, U.S. Expansion)
A favorite among the more design-conscious crowd, the ScanWatch 2 blends analog aesthetics with serious medical sensors:
- Medical-grade ECG and SpO₂
- Nighttime respiratory rate and atrial fibrillation alerts
- Long battery life (up to 30 days!)
- Sleep score and overnight breathing disturbance tracking
Withings is gaining popularity in U.S. clinical trials, and its app now syncs seamlessly with Apple Health and Google Fit.
3. Samsung Galaxy Watch 7 Pro (Best Android Option)
If you’re in the Android world, Samsung’s 2025 release is your go-to. The Galaxy Watch 7 Pro includes:
- FDA-cleared ECG and blood pressure monitoring (yep, real cuff-less BP!)
- Blood oxygen and sleep apnea screening
- Stress tracking via HRV and electrodermal activity
- Onboard GPS and fitness features
It also boasts a battery that lasts a couple of days, which, let’s be honest, is better than Apple’s 18-hour window.
4. Fitbit Sense 3 (Most Budget-Friendly Medical Features)
Yes, Fitbit’s still in the game—and the Sense 3 is quietly doing the most for your money. It now offers:
- Afib detection and ECG
- Skin temp trends, sleep scores, and nightly oxygen estimates
- Deep stress insights and mindfulness tools
- One of the easiest dashboards to understand
Great for users who want accurate wellness data without the price tag of other brands. Just note: It’s not quite as detailed for cardiovascular risk as Apple or Samsung.
5. Movano Evie Ring (For Those Who Hate Watches)
Okay, not a smartwatch—but too good not to mention. The Evie Ring, newly cleared by the FDA, is designed specifically for women’s health and rivals many watches in function:
- HRV, SpO₂, skin temp, and menstrual tracking
- Clinical-grade pulse oximetry and heart rate
- Focus on sleep quality and cycle health
It’s subtle, stylish, and more comfortable for 24/7 wear. Perfect if you want the data without the bulk.
