What's the difference between a service and an attribute?
A “service” is an app you use to sync data into Exist. For instance, Fitbit, Todoist, and Oura are all services. An “attribute” is a single type of data that you track about yourself, such as the number of tracks played or number of steps you took today. Your time active is also an attribute, as are wind speed, min temperature and max temperature, which we get from WeatherKit.
