When an alarm is activated, the pillbox will begin to flash its lights and make a "ping" sound every five seconds. An alarm lasts fifteen minutes, or until you disable it -- either by taking your medication or indicating that the dose was skipped, using the sensor on the pillbox. Meanwhile, you will receive a push notification on the app. These notifications basically just alert you that an alarm should be going off on your pillbox somewhere and that you have medication to take. In the case that you are not close enough to your pillbox to hear an alarm or its battery dies, the notifications serve as another line of defense against the possibility that you do not take your medication. Because these are merely just reminders, dismissing them does not affect the alarm itself, which must be disabled on the physical pillbox separately.
