What is Kai Companion? Kai companion is an offline personal safety app for iPhone that runs entirely on-device and sends location and alerts to trusted contacts via standard SMS and phone calls without requiring contacts to install an app. It provides silent triggers (voice, button, timer, fall detection) and automatic SMS with Apple Maps location plus an auto-call to a primary contact; all triggers operate without Wi‑Fi or cellular data. Health monitoring integrates with Apple Health and Apple Watch to track heart rate variability and activity for alerts and trend detection; fall detection uses a three‑phase algorithm with a cancel grace period. The app supports lock screen widgets, Dynamic Island and Live Activities, Siri voice activation, customizable SMS templates in six languages, check‑in timers, nearby safe places via Apple Maps, and an end-to-end test mode. Configuration is local—add trusted contacts, set message templates, and choose safety modes—so no account or server dependency is required.Suitable for solo travelers, commuters, night-shift workers, older adults, and caregivers who need silent, offline emergency alerts, automated location sharing, and deep Apple ecosystem integration.
