Abstract: User interface elements relating to fitness may be shared between user devices. These user interface elements may be updated based at least in part on activity data of users associated with the user devices. Once a sharing relationship between at least two users has been established, updates corresponding to user interface elements may be shared between the users via their respective user devices.

Abstract: Notifications for instructing user behavior can be determined and presented when appropriate. The timing of when to present the notification can be based on a device being in a worn state, configuration data, and/or an open time on a user calendar.

Abstract: Coaching notifications can be determined based on current user fitness data and historical user fitness data. The coaching notifications may include information that encourages or otherwise coaches users towards established fitness goals. To this end, the timing for presenting along with the substance of the coaching notifications can be customized to the users.

Abstract: Embodiments of the present disclosure can provide systems, methods, and computer-readable medium for tracking the heartrate of a user using different techniques associated with different contexts. For example, motion of a user wearing a wearable device can be tracked using at least first sensors of the one or more sensors. The physical state of the user can also be tracked using at least second sensors of the one or more sensors. In some cases it can be determines whether an application of the wearable device has been launched. Additionally, an activity category of the user can be determined based at least in part on the motion of the user, the physical state of the user, and/or whether the application has been launched. Heartrate data of the user can be collected, and the heartrate data can be categorized based at least in part on the determined category.

Abstract: Sleep alerts associated with an alarm can be scheduled using a first electronic device. Once scheduled, data can be collected from a second electronic device. This data can be used to determine an appropriate device, other than the first electronic device, at which the sleep alert can be presented. Once determined, the information can be sent to the appropriate device for presenting the sleep alert.

Abstract: Systems, methods, and computer-readable medium are provided for providing dynamic rule-based messages. For example, a user device may identify physical activity information. Based at least in part on the activity information, the device may determine whether a physical activity goal has been reached. The device may determine whether to present a dynamic progress update message based at least in part on a time since a first activity message was presented and whether the physical activity goal has been reached. In some instances, when it is determined to present the dynamic progress update message, the device may access a data structure configured to maintain progress update information associated with respective time intervals. The device may then retrieve the dynamic progress update message that corresponds to a particular time interval from the data structure. The device may also present the message for the particular time interval.

Abstract: An adjustable alarm indicator of an alarm application is described. The adjustable alarm indicator may be presented in connection with an alarm setting sequence. The adjustable alarm indicator may include a variable element having a variable annular shape, a first element associated with a first end of the variable element, and a second element associated with a second end of the variable element. The first element may be independently moveable to adjust the size of the variable element. The second element also may be independently moveable to adjust the size of the variable element.
