Our integration with Fitbit pulls in your activity data to adjust your daily water goal and then pushes the water data back to the FitBit servers.
For the Fitbit steps to display in Hidrate app, you will need to open the Fitbit app to let your steps sync there first. Then, your steps will be automatically updated in the Hidrate app.
The water you consume should show up within Fitbit's web portal once your bottle has synced with the Hidrate App. You must have an internet connection for this to work, and it may take some time to show within the Fitbit app, as the data in their servers is not immediately pushed to their mobile app. To check that the integration is working, add some water within the Hidrate app, and then log onto the web portal for your Fitbit account and check that it has added the water.
