Yes — if your main goal is accurate heart-rate tracking for workouts plus reliable all-day use, the best choices depend on whether you want a watch or a dedicated fitness band/chest strap.

Best overall heart-rate wearables

1. Apple Watch Series 9 / Ultra 2

  • Best for: iPhone users who want strong overall accuracy and smart features
  • Why it stands out: Very good optical heart-rate tracking in daily use and most workouts, plus excellent app support
  • Notes: The Ultra 2 is better for endurance athletes, outdoor use, and longer battery life

2. Garmin Forerunner 265 / 965

  • Best for: Runners, cyclists, and endurance training
  • Why it stands out: Strong workout tracking, great training metrics, excellent battery life
  • Notes: Garmin’s wrist HR is good, though for intense intervals or strength training a chest strap is still more accurate

3. Fitbit Charge 6

  • Best for: A simpler, lighter device with strong heart-rate and sleep tracking
  • Why it stands out: Good everyday wear, compact form factor, solid health features
  • Notes: Great value if you don’t need a full smartwatch

4. Samsung Galaxy Watch 6 / 7

  • Best for: Android users who want a smartwatch plus health tracking
  • Why it stands out: Good general HR tracking and useful smartwatch features
  • Notes: Accuracy is decent, but for workouts Garmin and Apple often do better

5. Polar H10 chest strap

  • Best for: The most accurate workout heart-rate tracking
  • Why it stands out: Chest straps are generally more accurate than wrist wearables, especially for intervals, HIIT, lifting, and fast HR changes
  • Notes: You can pair it with many watches, phones, and apps
  • Important: This is not ideal for all-day wear, but it’s the gold standard for exercise accuracy

If you want the most accurate setup

A very strong combo is:

  • Everyday wearable: Apple Watch / Garmin / Fitbit
  • Workout accuracy boost: Polar H10 or Garmin HRM-Pro Plus

Quick buying guidance

  • iPhone + best smartwatch experience: Apple Watch Series 9 or Ultra 2
  • Android + smartwatch: Galaxy Watch 6/7
  • Fitness-first + best battery: Garmin Forerunner
  • Lightweight + affordable: Fitbit Charge 6
  • Best exercise accuracy: Chest strap like Polar H10

A useful note on accuracy

Wrist-based heart-rate sensors are usually:

  • Good for steady cardio and everyday monitoring
  • Less accurate for intervals, HIIT, weightlifting, and cycling grip positions

If your workouts include a lot of those, a chest strap is the most dependable option.

If you want, I can also give you:

  2. a best for iPhone vs Android list, or
  3. a comparison chart of accuracy, battery, and price.
