Best Health & Fitness Trackers

Q: Can a wearable detect if I'm getting sick?

Wearables cannot diagnose illness. However, many users report seeing changes in their data—like a sudden drop in Heart Rate Variability (HRV), an elevated resting heart rate, or a higher body temperature—a day or two before they feel symptoms of an illness. This can serve as an early warning to rest and recover.

The 2025-2026 Guide to the Top 10 Wearables. We tested the latest smartwatches, smart rings, and bands for accuracy, sleep tracking, and overall value.

Frequently Asked Questions

Your top questions about health and fitness trackers, answered.

What's the difference between a smart ring and a smartwatch?

A smartwatch (like an Apple Watch or Garmin) is a feature-rich device with a screen, GPS, and apps, ideal for on-the-go data during workouts. A smart ring (like an Oura or Samsung Galaxy Ring) is a screenless, comfortable device that excels at 24/7 background tracking, especially for sleep, recovery, and stress (HRV), without the distractions of notifications.

How accurate are sleep trackers?

Consumer wearables are not as accurate as a clinical sleep study (polysomnography) for precise sleep staging. However, they are highly effective at tracking trends in your sleep patterns, duration, and consistency. They use metrics like heart rate variability (HRV), resting heart rate, and movement to provide a 'sleep score' that is a very good indicator of your nightly recovery.

Do I need to pay a subscription for a fitness tracker?

It depends on the device. Some, like Garmin and Samsung, provide all their data for free. Others, like Oura and Whoop, require a monthly subscription to unlock in-depth analysis, trends, and personalized recommendations. Always check the subscription model before buying.

Can a wearable detect if I'm getting sick?

Wearables cannot diagnose illness. However, many users, including our testers, report seeing changes in their data—like a sudden drop in Heart Rate Variability (HRV), an elevated resting heart rate, or a higher body temperature—a day or two before they feel symptoms of an illness. This can serve as an early warning to rest and recover.

Final Verdict: How to Choose Your Perfect Tracker

Choosing the right wearable in 2025 comes down to your primary goal.

For serious athletes: Get the Garmin Fenix 8. The data is unmatched.
For optimal sleep and recovery: Get the Oura Ring 4. The comfort and insights are life-changing.
For the best all-in-one smartwatch: Get the Apple Watch Ultra 3 (for iPhone) or Pixel Watch 3 (for Android).
