MacroFactor has three primary data integrations: Fitbit, Health Connect, and Apple Health. We allow you to select separate integrations for each data type. Right now, here's how those data sources are supported:
Support will be expanded in the near future.
In addition to integrations, manual entries and MacroFactor's own food logger are exposed as data sources as well. Higher-priority sources will take precedence over lower-priority sources if you have weight or nutrition data coming from multiple sources. You can read more about priority here.
For example, priority is always "Manual", followed by "Food Log", followed by Apple Health/Google Health Connect, then Fitbit. If you didn’t enter a manual nutrition estimate for the day, nutrition information logged in MacroFactor’s food log will take priority. So, if you logged 2000 calories in MacroFactor’s food log, and 400 calories in another nutrition app that can sync data into MacroFactor via the Fitbit app, MacroFactor will record the nutrition data entered in the MacroFactor food log as your intake for the day.
Note that priorities cannot be edited, and MacroFactor’s own internal entries will always have priority over synced data entries from external sources, meaning that if you have a manual or food log entry in place within MacroFactor for the day, it will always have higher priority and prevent a sync from occurring for that day.
