Fitness tracker calories burned numbers seem wrong
Fitness trackers estimate calories based on heart rate and movement, and those estimates are wrong. The tracker doesn't know your weight, fitness level, or what exercise you're actually doing. It just guesses. Most trackers are off by 20-50%, so don't treat the numbers as exact.
Fitness trackers estimate calories burned using your heart rate, movement, and the time spent exercising. But the tracker doesn't know your actual weight, muscle mass, or fitness level. So it's making an educated guess, not a precise measurement. That's why the numbers look wrong compared to what you expected. The tracker gets better the more you use it and let it learn your patterns, but these numbers are estimates, not facts.

Skip — I just want a technicianCommon mistakes to avoid
- Comparing your tracker's calorie count to online calculators. They use different math and will never match
- Relying on calorie estimates to track diet or weight loss. Use actual measurements instead
- Not entering your weight. This creates huge estimation errors
Signs you need professional help
- The calorie numbers are missing entirely or the tracker shows zero calories for a full workout Heart rate data isn't being recorded at all even though the sensor looks clean The estimates are wildly different from other devices you've tried
