iOS app - graph weight target incorrect

[Ian64]

The target line on the weight iOS app weight chart is incorrect. I have a weight target of 11st13lb, yet the target line is rounded down to 11st. I'm nearly at my target, 3.9lbs to go, yet the graph is showing that I have 1st 3lbs to go... The red line below is where the target line should be.

I'm going to need an accurate graph soon so I can document my achievement. It will be a shame if I have to doctor the graphs just to make them accurate.

Hi @Ian64. It's good to see you here in the forums.

Thanks for the detailed information and the screenshot provided. I understand how you're feeling about the graph not showing the correct details. Just to confirm, does the same happen when visiting your fitbit.com dashboard? Do you recall since when this started to happen? Also, what's the model and OS of your phone?

In the meantime, let me suggest the following steps:

1. Log out from the Fitbit app.
2. Force quit the Fitbit app and reboot your phone.
3. Open the Fitbit app and log back into your account.
4. Tap the Weight tile > Edit Goal.
5. Set your weight goal one more time and check if the graph changes.

Hope this helps.

Hi @LizzyFitbit 

iPhone 13 Pro, latest version of FitBit and iOS. No idea when it started. My previous phone was iOS 12.5 so it was a much older version of the app. It only becomes an issue as you near the target, or in the case of the stone graph, don't get near the target.

You don't have to do the quit/reboot/edit etc to see the problem affects only the stone/lbs graph. Simply setting the app setting for units preference for weight to be Stone. See side by side comparison below. Setting weight = kilograms will match the Pounds setting, which are both as I would expect.

Incorrect Stone unit graph on left. Correct line should be green. Pounds unit graph on left shows red line that Stone graph is showing as the weight loss target.

You can see that as well as the target line being incorrect on the Stone graph, the graph scaling is much compressed. This is even more noticeable on the 1 month graph where the stone graph is fairly smooth as it has been scaled to include the additional 13 lbs (11st vs 11st13lbs).

Its easy to see yourself, just change units in app settings and make sure your target weight is not a multiple of 14 lbs (1 stone). What it looks like is that the stone graph is rounding the target weight down to the nearest stone, which is fundamentally incorrect, and scaling the graph to also include the incorrect target weight.

Hope this helps.

Unimportant personal info obscured but otherwise full screen view.

For reference, in these graphs, 2.7lbs to target weight, so a tiny gap expected below the graph to target weight line, not the big gap as in the left stone unit graph.
