APNS for iOS mobile devices
MangoApps uses Apple Push Notification service (APNs for Short) as a fast, reliable way to keep you in the loop. It is a robust and highly efficient service for sending information to devices such as iPhone, iPad, and iPod touch devices. Each device establishes an accredited and encrypted IP connection with the service and receives notifications over this persistent connection. If a notification for MangoApps arrives when it is not running, the device alerts the user that MangoApps has data waiting for it.
