Every device provider is different. In general the lifecycle of data from your wrist or pocket tracker is the following:
- Provider servers (Fitbit etc...)
- KrowdFit Data notification
- KrowdFit servers
- KrowdFit app
That data round trip can take up to 12 hours, in some cases it is much quicker. Additionally, KrowdFit performs a manual sync each night to make sure we didn't miss anything throughout the day.
