A system and method of contextually filtering content presented to a user on a mobile device based on contextual tagging. The user controls how content will be filtered by the mobile device by creating contextual tags and associating or tagging content with the contextual tags. The contextual tag includes a contextual behavior that is either satisfied or not based on the current context of the mobile device. During operation, content accessible to the mobile device is searched to determine which contextual tags are met based on the current context of the mobile device. Content tagged with contextual tags whose behavior is currently met based on the current context of the mobile device are filtered and presented to the user. This allows the automatic presentation of a more manageable subgroup of content to the user on the mobile device based on the current context of the mobile device.
