KrowdFit is able to read data from Google Fit. You'll first need to make sure you have Google Fit on your Android device and that your phone or tracking apps are working with Google Fit and have permissions to share. After that you can connect your Google account to KrowdFit through the Fitness Trackers page or contact support.
One thing you should know, Google does not currently notify us when new data is available. We check periodically throughout the day but data may be up to 24 hours delayed. You can force a sync more often if you like by going to the Settings > Fitness trackers page and sync the day on the Google Fit section.
