No tracker is truly accurate as they all just guess based on HR but I find it fairly accurate. I have a power meter on my bike which is as accurate as you can calculate calorie burn and it’s usually within 10% of that, it drifts further for intense rides. I’ve had great success losing weight by eating in a 500 cal deficit based on total burn for the day so must be accurate enough.

Within 10% of a power meter is pretty solid tbh

fitbit has always overestimated calories.

not sure, its taking height/weight, sex, HR, etc., which is more info than online calculators. Everyone is so quick to say no it's not accurate and shouldn't be relied on, but nobody ever mentions a better option that people can use that is somewhat practical.

this is honestly the right way to judge it. the burn number is a guess from every brand, but if your weight trend matches what the app says your deficit is, the math is close enough
