South Africans concerned about their personal security have several smartphone apps they can install to get help from emergency services at the tap of a button.
Many free panic button apps rely on alerting your friends or family, most of whom don’t necessarily “respond” or very quickly. Most of the services listed in the linked article are around R30 pm to R35 pm, which is really affordable. Even though you may have armed response for your home, this type of service compliments that by providing response for when you are out driving or walking anywhere too.
