Methods, systems and apparatuses for automatically detecting and sharing user stays of a mobile device of a user are disclosed. One method includes persistently collecting location information, determining a group of users for sharing the user stays, determining whether the mobile device is within a specific distance of a specific location for at least specific minimum duration based on the location information, determining a user stay based on the location information and the specific… Show more

Methods, systems and apparatuses for automatically detecting and sharing user stays of a mobile device of a user are disclosed. One method includes persistently collecting location information, determining a group of users for sharing the user stays, determining whether the mobile device is within a specific distance of a specific location for at least specific minimum duration based on the location information, determining a user stay based on the location information and the specific distance, determining if the user stay is private or public to at least a portion of the group of users based on preferences of the user and the location information, and sharing the user stay with the at least the portion of the group of users by sending notifications to the group of users if the user stay is determined to be public to the at least the portion of the group of users.
