Each night, the app downloads the previous day's data and imports it into your spreadsheet and calendar.
You can view your activity data, spreadsheet and calendar through the app.
You can also use any device to view your spreadsheet and calendar on the Google website, independently of the app.
The app requires permission to access your Fitbit data, Google Spreadsheets and Google Calendar in order to function. The app uses the Oauth2 protocol to authorize and access your data.
