## What is Kai Companion?

Kai Companion is a personal safety app for iPhone and iPad. It protects users by sending automatic SMS alerts with their current location and placing phone calls to trusted contacts when triggered — all without requiring an internet connection. It also works with Apple Watch for fall detection and vital signs monitoring.

## Key Features

- **Silent Triggers**: Activate safety alerts via voice command (Siri), a button press, or a check-in timer — silently and discreetly.
- **100% Offline**: All features work without Wi-Fi or cellular data. SMS, calls, fall detection, and voice commands use native iOS capabilities.
- **Fall Detection**: Automatic alerts when a fall is detected via iPhone or Apple Watch sensors.
- **Vital Signs Monitoring**: Tracks heart rate, blood oxygen, and other health metrics via Apple Watch and HealthKit.
- **Safe Places**: Finds nearby help points like police stations, hospitals, and pharmacies.
- **Live Activities & Dynamic Island**: Real-time safety status on your lock screen and Dynamic Island.
- **Widgets**: Home screen and lock screen widgets for instant access to safety triggers.
- **Companion Mode**: Intelligent monitoring that watches over you throughout the day.
