Abstract: A user input may be received at a user device to begin a breathing sequence. First heart rate information may be presented on a display of the user device during a first phase of the breathing sequence. A fluctuating user interface element may fluctuate on the display of the user device during a second phase of the breathing sequence. Second heart rate information may be presented on the display of the user device during a first phase of the breathing sequence.

Abstract: A user fitness goal may be determined based at least in part on i) historical fitness data that was tracked by a fitness application during a plurality of periods that together correspond to a historical period, or ii) or a user input. Current fitness data may be tracked by the fitness application during a current period. A coaching notification may be determined based on the current fitness data and the user fitness goal. The coaching notification may correspond to progress toward achieving including a suggested action for achieving the user fitness goal prior to a conclusion of the current period. The coaching notification may be provided for presentation at a user device.

The technique may also include tracking a physical state of the user using at least second sensors of the one or more sensors of the wearable device. The technique may also include determining whether an application of the wearable device has been launched. The technique may also include determining an action category of the user based at least in part on at least one of the motion of the user, the physical state of the user, or whether the application has been launched. The technique may also include collecting heartrate data of the user. The technique may also include categorizing the heartrate data based at least in part on the determined action category.

Abstract: A configuration for a breathing sequence may be defined using a user interface of a user device. The user interface may also be used to begin the breathing sequence. Prior to beginning the breathing sequence, the user device can determine a breath ratio for the breathing sequence based on a breathing profile. The breath ratio is based at least in part on inhale time and exhale time of a breath of the breathing sequence. During the breathing sequence, a fluctuating user interface element may fluctuate at a cyclic rate corresponding to the breath ratio. Such fluctuation may include repeated growing and repeated shrinking of the fluctuating user interface element.

Abstract: Notifications for instructing user behavior can be determined and presented when appropriate. Current fitness data are accessed. This data is used to determine whether a user fitness goal is likely to be achieved. If not, a notification may be determined and presented at a user device.

Abstract: A server system may establish sharing relationships between multiple user devices to enable sharing of user interface element data. A first communication including a first invitation to share a first updateable graphical user interface element may be received from a first user device. The first communication may be sent to a second user device, which may enable acceptance of the first invitation at the second user device. It may be determined that the first invitation has been accepted. A data structure may be updated to enable the second user device to receive updates corresponding to the first updateable graphical user interface element.

Abstract: First interaction data may be received and used to determine a beginning sleep time. Second interaction data may be received and used to determine an interrupted period during an expected sleep period. Third interaction data may be received and used to determine an end sleep time.

Abstract: Sharing relationships may be established with multiple user devices to enable sharing of user interface element data. A view of a user interface may be presented that includes an activity user list. The activity user list may include user identifiers of activity user and updatable graphical fitness user interface elements. A detailed view of for a particular activity user may be presented.

Abstract: A user interface is provided to schedule a sleep schedule associated with an alarm. Various user interface elements may be presented using the user interface. Responsive to user selection of these user interface elements, certain actions may be performed to configure aspects of the sleep schedule.

Abstract: A server system may facilitate and participate in operations relating to physical activity goals being performed at user devices. For example, the server system may receive a physical activity goal from a first user device associated with a first user profile. The server system may also receive an identification of a reward corresponding to the physical activity goal from the first user device. The server system may also transmit at least the physical activity goal to a second user device associated with a second user profile. The server system may also receive, from the second user device, first information associated with the physical activity goal. The server system may also transmit second information associated with the reward to a third device.

Abstract: Techniques are provided for tracking heartrate metrics using different operating modes associated with different contexts of a wearable device. For example, a heartrate sensor of the wearable device may be operated in a first operating mode when an activity is being tracked within an application session of a particular application. The heartrate sensor may be operated in a second operating mode after detecting conclusion of the activity within the activity session (e.g., during sedentary time).
