For mobile users, CLARITY displays glucose data from a Dexcom CGM system 3 hours after the data is captured. This means that the most recent data you view in CLARITY is at least 3 hours old.
For Dexcom Receiver users, the data is as current as the last upload.
It is possible to use both a smartphone and a receiver to provide CGM data. The smartphone system streams data to the CLARITY server, where that data is made available for reports after three hours. The Dexcom receiver requires connection to a computer to upload the data periodically. If the patient uses a smart device part of the time and a receiver part of the time, then CLARITY needs data from both to provide accurate statistics.
