In one aspect of the disclosed implementations, a device includes one or more motion sensors for sensing motion of the device and providing activity data indicative of the sensed motion. The device also includes one or more feedback devices for providing feedback, a notice, or an indication to a user based on the monitoring. The device also includes one or more processors for monitoring the activity data, for determining one or more activity metrics based on the activity data, and for causing one or more of the feedback devices to produce an indication to the user that an activity goal has been achieved by the user based on one or more of the activity metrics. The device further includes a portable housing that encloses at least portions of the motion sensors, the processors and the feedback devices.
