Have your words ready when speaking is difficult. Aegis SOS helps you communicate with people nearby, while traveling or when asking for help. SHOW IT OR TYPE IT Use large text cards with adjustable size and contrast, and rotate the card to face the other person. Take turns typing in a temporary conversation. KEEP PHRASES CLOSE Create, edit, categorize, search and pin phrases. Import or export phrase backups. Text cards and saved phrases work offline; spoken playback needs a suitable system voice available on the device. CHOOSE SPEECH OR LIGHT Read text with iOS voices and adjust the speaking rate and volume. Use built-in SOS light signals, steady screen light or a slow pulse. Voice and torch availability depend on the device and system settings. Flashing light may affect people sensitive to it. REVIEW BEFORE SHARING Type an address or request one location fix; there is no background tracking. Save up to five contacts. Edit and preview your message before copying it, choosing a sharing app or opening the SMS composer. You confirm sending yourself; SMS requires a compatible device. ONE-TIME ADVANCED TOOLS Core cards, conversations, phrases, speech, standard SOS, screen light and sharing tools are free. A one-time in-app purchase unlocks custom flash rhythms and text-to-Morse for A-Z, digits and supported symbols. Restore purchases in the app. No subscription. No account is required. Temporary conversations are not saved to history or uploaded. The interface includes 50 language and regional variants, with layouts for iPhone, iPad and supported Duo folding states. Aegis SOS is a communication aid. It does not automatically call emergency services, send messages or dispatch rescue. It cannot replace local emergency services. Speech and light can be interrupted and attention from others is not guaranteed.
