    Anyone else with both Fitbit and Apple watch...

    Do you notice a big difference between the two in daily step count/distance, calories, stairs?

    I'm thinking that the devices have different methodologies for calculating these.

    I had a Fitbit Charge and wore it for about 4 hours on my right wrist with Apple watch on my left. Went for a long walk during that time and received 4020 steps on Apple Watch and 3994 on the Fitbit. So it's about the same as far as steps are concerned.

    The thing I like about AW is that it's not focused on steps at all, but rather focuses on active calories and exercise time. I twisted my ankle yesterday so I had to walk much slower than normal today. I noticed around 4PM that even though I had over 6,000 steps, I only had 1 minute of exercise time since I walked slowly all day.

    Misunderstood thread title... I was expecting some sort of blender video link. #

    I have an Apple watch and a Fitbit One. I only keep the Fitbit to track my sleep and flights of stairs. I hope to be able to let it go soon.

    As far as step tracking they are more alike than different, but there are days they are very off. Myesterday for example there was about a 2000 step difference which I know was do to the fit bit tracking a bike ride as steps while the watch didn't. On the whole I would say the watch counts less steps than the Fitbit but most days it isn't much. All that said, I've always thought the Fitbit was count high, but that is just an impression I can't prove.

    Yes. Fitbit steps are always much higher than watch for me.

    Calories burned must also be calculated differently. I think I read here that the watch calculates calories using heart rate. Watch tells me 430 calories, Fitbit shows over 2,000.

    Fitbit shows total calories. The watch only shows active calories, but you can access the information on total calories on the Activity iPhone app.

    Fitbit is always high for me, or Apple low, but Fitbit has always been known to be high.

    Like others on this thread, the Fitbit count always seems to be higher than my Apple Watch.

    I find that it is about 10% higher.

    Completely agree. I have actual numbers that agree with this after much sampling over multiple users. It is about a 10% difference on average.

    I am sure they do have different ways of interpreting the data. Even the same device would vary from day to day walking the same distance. Which arm it was on would make a difference.

    Heck, 90 minutes on my riding mower gave me over 1600 steps so we know that devices are going to error.

    I have a Fitbit Zip. Goes in my pocket the minute I wake up and stays there until bedtime. Before Apple Watch it had always run about 2,000 steps higher every day compared to what my phone and the Health app said.

    I had hoped the Apple Watch would bring the numbers closer together. Nope... A week of wearing the Watch and I'm still about 2,000 steps a day less on the Watch/iPhone that on the Fitbit...

    Kind of disappointing as I'm wearing the watch as much as the Fitbit. The phone gets put down here and there during the day so I knew it wasn't logging everything. I really want my watch to be logging all my steps...

    It's notoriously difficult to track steps from the wrist, so it's not a surprise that comparing a wrist-based fitbit with an Apple watch will result in broadly similar counts, but comparing a body-worn fitbit such as the One or Zip will result in commonly lower count on on the watch than the fitbit.

    One of the common issues with tracking from the wrist is that the accelerometers have to untangle much more complex motions, but at the same time, if the wearer is carrying something, or pushing a buggy for example, the movements are damped out and harder to accurately detect.

    As an example, if I go on an hour-long walk in my neighborhood, my fitbit one and Apple watch will usually give readings within about 4-5% of each other, with the watch generally a little lower than the fitbit. If, on the other hand, I have a typical day which includes 45 minutes in the supermarket, some carrying of equipment, carrying my bag to and from work etc, the difference can be as much as 10,000 steps in a 30,000 step day, with the watch always lower.

    The result is that I still use the fitbit, because it has always returned consistent results where wrist-based trackers never have. I don't bother with the fitbit site however, since I'm only monitoring my own activity for my own sake. Where the watch is very good is the inclusion of the activity rings, which quickly and graphically represent a snapshot of my day, and are highly motivating as a consequence. The actual numbers the activity app provides for movement and exercise aren't all that useful, though the stand reminders and 12 hour goal are very helpful.

    One area where the watch seems to fare much better than any of the wrist-based trackers I have tried is that it appears far less prone to false-positives - counting arm movements, waving, clapping etc as steps when they are not.
