in Getting Started
I walk a certain route. I always wear my Fitbit and have also carried my phone and ran map my walk. The first few times a did this- it seemed my Fitbit and map my walk were showing the same number of miles. Tonight the map my walk showed .50 mile more than the Fitbit. Is this a glitch? Or is there some other reason this may have occurred?

    If you track your walk in the Fitbit app, then it uses GPS to calculate the distance. If not, it just multiplies the number of steps times your stride length.

    I don't know how MapMy calculates distance.

    Fitbit app has GPS to track the route. Don't even need to have/use one of their pedometers to use the app to track the route (basically what/how MapMyWalk does).

    In the past, I found MapMyWalk to overestimate my route consistently so I just stick with the Fitbit app.

    My suggestion is to just use one instead of both. Otherwise you'll constantly be trying to figure out which to use and why there are discrepancies.

    I have Runkeeper and Fitbit. There are occasions when the GPS on Runkeeper goes wonky and calculates my walks as .5-1.5 miles further than I actually did. I didn't care for Fitbit's GPS when I used it.

    you're lucky, the couple of times my "map my walk" was off, it was only by about 0.3 miles but not in my favor. I actually walked farther than it calculated, and this is on a known route that I've taken several times. and most of those time I was using the program and it gave the correct mileage. a little research showed a few things that could have happen like needing to restart my phone, too much cloud cover (not likely in San Antonio) having too many things running on the phone at the same time, ie: email, wireless etc.

    None of the apps are totally consistent with each other or 100% consistent with themselves from day to day. GPS is not perfect.

    I walk the same route and it is never the same.

    can you drive the route to see which is right?

    Why drive? You could just map it on google maps. I'm not sure how driving it would give you a better read out? Unless you are assuming her car has GPS and even so - that's now adding in a 3rd device.

    Or do you mean relying on the odometer? Just seems like a lot of work and overthinking the situation.

    It's in a state park so driving is not an option. A trail in the park. I just wondered what could affect this.

    you're moving faster, GPS is apparently more accurate at faster speeds as you move more per unit time - or so a Running app developer told me.

    I have found map my run to be inaccurate when it comes to distance and calories burned. Probably the same for map my walk.

    It does provide some insight as to why maybe we shouldn't eat all those exercise calories and why some are not losing when they think they are doing everything correctly.

    Excellent point!

    The only way to gauge the accuracy of any device is to trust it for several weeks then reevaluate your progress. I eat back 100% of my Fitbit adjustments, lost the weight & kept it off.
