Android now automatically removes permissions for apps that have not been used recently. Keep Alive, once the settings are configured, does not need any further interaction and may have its permissions revoked, possibly preventing it from sending an Alert. Keep Alive was designed to operate as unobtrusively as possible and, as an alternative to bugging the user to open the app periodically, expects this behavior to be disabled. On the most recent version of Android this is called ‘Pause app activity if unused’ and can be found on the App Info screen for Keep Alive.

Keep Alive was created after separate incidents with colleagues who lived alone and lost consciousness at home. One was found within 24 hours by a concerned friend doing a welfare check and was saved, albeit not unscathed. The other was not discovered for more than 36 hours and sadly succumbed to his injuries after several days in the ICU. If they had been found even a few hours sooner, things may have turned out differently. I am hoping that this app can help prevent similar tragedies in the future.
