The activity numbers showing on tracking device/app and your Count.It activity page should be the same. That said, the difference may be transient — due to data synchronization lags over the course of the day. Count It checks for new activity data across all of the connected trackers every two hours.
For Count It to get your most recent data, you must “sync” your tracking device or app with its servers, and then Count It can grab the data. If you click the “sync” button at the top of your Trackers or Activity Log pages, you will prompt the system to look for new data immediately.
Activity data and the resulting Count It score for any given day may change as new activity data is reported. Usually, the differences settle out over 24 hours.
