Whether you're commuting home, out at night, traveling solo, working out, or simply want peace of mind for yourself or a loved one: Kai is ready. One tap or voice command alerts your people instantly – no internet required, no app on their end.
Kai sends an SMS with your location and calls your trusted contacts directly. No sign-ups, no subscriptions, no delays. Just real help, fast. And beyond emergencies, Kai acts as your safety buddy – always aware of what's around you, giving you the right info at the right time.
Safe. Local. Immediate.
EMERGENCY CHAIN – HELP IN SECONDS
Hold the safety button or say "Hey Siri, Bravo" – Kai sends an emergency SMS with your live Apple Maps location and calls your contacts one by one. Works offline. Completely silent. Setup takes under two minutes.
YOUR SAFETY BUDDY
Kai pays attention so you don't have to. Based on time of day, weather, location, and your activity, Kai sends you smart safety tips and shows nearby help like police stations, hospitals, and pharmacies.
COMPANION MODE
One tap activates a Live Activity on your lock screen and Dynamic Island – instant access to trigger help without even unlocking your phone.
CHECK-IN TIMER
Heading out? Start a timer. If you don't check back in, Kai warns you first – then triggers the emergency chain automatically. Perfect for late shifts, first dates, solo hikes, or nights out.
FALL DETECTION
Three-phase fall detection using your iPhone's sensors. If you don't respond within 60 seconds, the emergency chain activates. No Apple Watch needed.
HEALTH MONITORING
Kai reads your heart rate trends from Apple Health and alerts you to unusual patterns over 7 days – so you stay informed about your body.
SAFETY ZONES
Get notified when you enter or leave areas you've defined – stay aware of your surroundings without thinking about it.
EVIDENCE RECORDING
Encrypted audio recording in emergencies – stored locally, auto-deleted after 7 days. No cloud, no upload, only yours.
