The LyfeShield app can be used by elderly users in need of protection and security. App while working silently (in the background), provides the capability to alert contact-persons (selected by the user), with text, sound and / or video using different modes (SMS, e-mail). Notifications are sent after a user action (giving a voice command, pressing a button, shaking the device), or whenever the application finds out that a certain activation condition is met (timer, inability to answer a question of the device).
