Cross device task continuity

Systems and methods for cross device and/or cross operating system task continuity between devices for frictionless task engagement and reengagement. Task continuity can provide for simple detection and selection of recently viewed and/or modified tasks. Task continuity can provide for simple engagement of new tasks in applications and/or websites, the new tasks being related to recently presented and/or modified tasks. Responsive to selection of the recently presented and/or modified task, the task can be seamlessly reengaged from the point at which it was last presented and/or modified. Responsive to selection of a new task, the task can be engaged from a starting point. Upon completion of the task on one device, the task can be closed across devices. Task continuity can be enabled on a single device or across a plurality of devices. Task continuity can be enabled on a single operating system, or across a plurality of operating systems.
