Note: It can take anywhere from a few minutes or up to three days to complete your first upload via the mobile app. Since it uploads your oldest data first, it may appear as though the app is not uploading, but the mobile app is uploading data to the Tandem Cloud and the Tandem Source platform every hour.

Share Reports with Your Healthcare Provider

Once your data is uploaded to your account, you can work with your healthcare provider to spot trends and make adjustments. Just share your reports with your clinic through the Tandem Source platform.
