Difference between activities-steps and activities-steps-intraday

[JSasaki]

Hello

This is a question about my customer's data.

In my system, I aggregate the number of steps for each user.

Regarding the data obtained with the endpoint below, I understand that activities-steps returns the total value for the day, and activities-steps-intraday returns the value for each minute.

URL: /1/user/[user_id]/activities/steps/date/[date]/1d.json

However, even when the activities-steps-intraday value was added up, there was a big difference with the activities-steps value.

Why is there a difference in the values ​​for these data?

Also, which should I use to know the exact number of steps, activities-steps or activities-steps-intraday?

Thank you in advance.

Hi @JSasaki - this may have a bearing on the issue as Google have been messing around with steps when syncing and it's still not resolved.

Hi @Guy_  Thank you for providing the information.

If you know, please let me know.
Which figure is closer to the actual situation, activities-steps or activities-steps-intraday?

My personal opinion is that activities-steps is a daily aggregation, while activities-steps-intraday is closer to the raw data, so I think I should refer to the activities-steps-intraday figure.

Hi @JSasaki,

Thank you for reaching out. Please note that the intraday totals reflect on-wrist data only. This difference in data sources may explain any discrepancies between the intraday and activity totals.

Hi @IncaFitbit 　Thank you for providing the information.

I now understand the difference in specifications between activities-steps and activities-steps-intraday.

If you know, please let me know.

The Fitbit app has a screen that displays the number of steps by granularity, such as daily or weekly, but am I correct in understanding that the number of steps by day is the number of activities-steps-intraday, and the number of steps by week is the number of activities-steps?

Hi @JSasaki 

My current understanding is that both data are from activities-steps and align with the data displayed in my Fitbit app.
Additionally, this post introduces how Fitbit devices calculate daily activity and provides tips for ensuring data accuracy.
