What to look for

1. Reliable heart‐rate and motion sensors
   Good calorie estimations depend on accurate detection of your exertion levels (e.g., via heart rate) and your movement. Healthy 4 Sure Blog+1
2. Good integration of your personal data
   The tracker should allow you to input (or automatically pull) details like your age, weight, height, gender, typical activity level—this helps it estimate your resting metabolic rate + activity calories. Asset Health+1
3. Clear explanation of what calories are being reported
   Some trackers report total energy expenditure (TEE = resting + activity), others only active calories. Knowing which you’re seeing helps interpret the numbers. Reddit
4. Good app and ecosystem support
   You’ll want the device to sync smoothly with reliable apps (or its own companion app) so you can review your burn data, trends over time, compare with intake etc. Quest Health Library+1
5. Durability & wearability
   Since you should wear it consistently (to capture all day’s activity and resting burn), things like battery life, comfort, water resistance matter. If you forget to wear it or it dies mid-day your data will be incomplete. Kings Way Gym

⚠️ Important caveats

• ✔ Even the best trackers estimate calorie burn—they are not lab-grade metabolic analyzers. Many studies show error margins of 20-30% (or worse) for calorie estimates. Fountain of Fit – Health is Wealth+1
• ✔ Be careful about relying on the calorie number for precise decisions (e.g., eating exactly based on it). It’s more useful as a trend or relative guide (e.g., “Today I burned more than yesterday”) than a perfect measurement. Fitness N Health+1
• ✔ If you only wear the tracker during workouts (not all day) you’ll miss large parts of your total energy expenditure (resting, non‐exercise movement).
• ✔ Make sure the data is calibrated: ensure you’ve entered your personal data correctly, and that you're consistent in how you use the device so comparisons over time are meaningful.

FAQ: The 10 Best Fitness Trackers for Accurate Calorie Counting in 2025
