Systems and methods are presented for providing notifications based on user activity data. In some embodiments, a method is presented. The method may include accessing first sensor data associated with a first activity of a user. The method may also include determining that the user is engaged in the first activity based at least in part on the first sensor data, receiving a notification while the user is engaged in the first activity, and determining to not present or in other words, hold the notification while the user is engaged in the first activity. In some embodiments, the method may also include accessing second sensor data associated with the user, determining that the user is no longer engaged in the first activity based at least in part on the second sensor data, and presenting the notification while the user is no longer engaged in the first activity.
