Mileage tracking is wrong when using the iPhone app to track a workout (Charge 2)

[SofaSpud]

For the last few weeks, I've been getting bogus mileage (and therefore pace) when I track my workout using the iPhone app.  What appears to be happening is that the GPS is showing a very zig zagging route when I'm moving in a straight line.

The result is that my miles are overstated, also affecting the pace logged.  (I did a sub 7 minute walk two weeks ago!)

I thought that was a one-time occurance, but it's now happening every time I use the app.  (I'd been using the app this way with this Charge2 for several months w/no issues.)

How do I fix this?

I am having the same issues. It started to go wrong this week. Overstates my distance by 5-10pc. My guess is on the hew update they changed the algorithm that connects the gps positions... 😞

I got an iPhone 7 Plus yesterday. My usual walk showed I walked 6.25 km!!! It's always been 5.5 km. My other route was normally 6.0 km. Today it was 7.3 km. WTF? Glad I checked the forum. Guess it's not my phone.

today was a bit better, only about 200m off on a 10km run.

I took a walk again tonight. Distance should have been around 6 km. It showed as 7.68 !!!

took a look at the map created and then zoomed in and this is what I saw. This stupid zigzagging is adding more mileage than I'm actually walking. WTF is going on? This started a couple of days ago. 

These red lines should be straight. I did not drink before walking.

Again. All this zigzagging is bogus. The lines should be straight

Same here! A bunch of zigzags....

I think the algorithm that calculates the distance is somehow buggy. There was a software update on the 25th of April. My guess is that something went wrong there!

Same here. What's the fix, Fitbit?

Same here. 

Help, Fitbit. 

Mom looking for replies to this thread but keep hearing crickets.

@FitbitPLEASE HELP!

Same here. 

My walk looks zigzagged and what I know to be 4 kilometers comes up as way more. And the same walk comes up different every day. 

Thought it was my phone.
