Aggregate data types

For data that can be continuously recorded (with multiple data points over a time period), the Google Fit platform can aggregate this data and return the calculated results. This can be an average measurement or a summary/total. You can save time on these calculations and show your app users useful summaries or averages easily by reading aggregated data.

Note: Aggregate data types exist to help you save time by reading calculated data. Only use aggregate data types to read data. Don't write to aggregate data types.

To read aggregated data, you need to pick a data type, time range, and something to 'bucket' (or group) the data by. You can bucket data in a few different ways:

Time period

Bucket aggregated data by per hour or per day. For example, see steps or calories burned per day.

Activity type

Bucket aggregated data by activity type. For example, for sleep data over a week, there will be a bucket for each sleep activity type (light, deep and REM).

Activity segment

Bucket aggregated data by the activity segments over a time period. For example, if a user went for a run between 9am and 10am but ran for the first 20 minutes, sat down for 10 minutes, walked for 15 minutes and ran for 15 minutes, these are considered 4 activity segments and would return 4 buckets.

Session

Use the time boundaries of sessions to aggregate data. For example, if a user went for 2 runs which were logged as 2 sessions (a morning run and an afternoon run), you can bucket by session to learn the average steps or average speed of each run.

Activity

Use these data types to read aggregated health and wellness data.
