Kai Companion is a free proactive safety app for iOS by Ka.I Health GmbH that helps users feel safer in everyday life, not just in critical moments. Using a predefined code word via Siri ("Bravo"), the app triggers an alert chain: trusted contacts receive an SMS with the user's location, and a primary contact is called directly. On top of that, Kai works proactively with fall detection, check-in timers, safety zones, and a smart buddy system that sends context-aware notifications throughout the day. Core safety features are free, with optional Kai Plus subscription for advanced tools.
