A wellness system including a personal wearable data-capable band is described. In some examples, a wellness system may include an aggregation engine configured to aggregate user activity data from sources, a feedback engine configured to process the user activity data, the feedback engine operable to communicate a feedback notification to a source device including at least one of the sources, and a user interface configured to display a graphical representation associated with an aggregate value determined from the user activity data and the feedback notification. In other examples, a method using a wellness system may include receiving user activity data from sources, processing the user activity data using an aggregation engine to determine an aggregate value, generating a graphical representation using the aggregate value, and displaying the graphical representation using a user interface.
