Apple Watch vs Fitbit tracker

Fitbit from my experience shows the whole amount of calories burnt per day including the inactive ones you naturally burn - apple just show the ones burnt through exercise in big and you can see at the bottom in total you did 2578.

It took me a while to adjust to this change from fitbit to apple when i got my watch

Looking at the fitbit figures 2747 calories burned for a distance of 6 miles,I don't think so,yesterday I did 7.5 miles and burned 700 calories,I should tell your friend his fitbit needs looking at."The general rule of thumb is that the average person burns 100 calories per mile of running" I got this quote from runnersworld.com.

You don't have to be doing a workout for the watch to start counting exercise minutes. Pretty much any time it sees an increase in your heart rate it can see that as exercise. Walking up the stairs, going for a quick walk to the mailbox, jumping from a sitting position and making a dash for the bathroom. Those can (not always) make the watch think you are exercising. The 421 is from today. The 2578 is from the 9th. It starts over at midnight every day.

The apple watch tells you your total calories as well,if you go into the health app on the phone and tap browse at the bottom then tap activity it says "active energy" which is calories burnt while exercising and "resting energy" which is the calories that you burn when you're not exercising,just add the 2 together and you get the total calories burned.

It's showing 25 calories.And that picture is NOT the health app.that 421 figure includes the calories you have burnt in order to stay alive.If you're in a coma you still burn calories.

Yes because 421 is the start of another day.
