How do I log BG meter values or calibrations* in the Dexcom G7 app?

To log a BG meter value or calibrate:
  1. In the app, tap + in the Glucose or History tabs
  2. Select Log Blood Glucose, or to use the BG value as a calibration, select Use as Calibration.
  3. Follow onscreen instructions.
*Please note: Your sensor readings come from different fluids than your BG meter values, so the two usually won’t match. Neither number is as accurate as the lab test your healthcare provider performs. For more information on accuracy and calibrating your Dexcom G7, refer to the Accuracy and Calibration section of the Dexcom G7 User Guide.
