Definition: emergency app


Software that notifies family and authorities in the case of an emergency. Phone numbers and messages are pre-stored in the app and triggered by pressing one button.

Survival apps prepare a user for an upcoming natural disaster such as a hurricane, and such apps may also provide essential first-aid information. If there is no cellular or Wi-Fi service, most informational apps have all the instructions already downloaded into the device ahead of time. See ICE.
