Frequently asked questions.
What is the Live Crime Map?
Kai's Live Crime Map shows real incidents like crime, fire, and emergency dispatch on a map around you, updated every minute from official city feeds. Tap any pin to see what happened and how close. Available now in 20+ US cities and expanding.
How does Kai work without an internet connection?
Kai's safety features run entirely on your iPhone. SMS alerts, phone calls, location sharing, fall detection, and voice commands all use native iOS capabilities that work offline. Your safety never depends on Wi-Fi or cellular data. The Live Crime Map needs internet to refresh, but everything else keeps working.
Do my contacts need to install an app?
No. When you trigger an alert, Kai sends a standard SMS with your current location and places a regular phone call. Your contacts receive help requests on any phone. No app required.
Is Kai available outside the Apple ecosystem?
Kai is available for iPhone and iPad, and works with Apple Watch for fall detection and vital signs monitoring. It is deeply integrated with iOS features like Siri, Dynamic Island, Live Activities, and HealthKit. There are no plans for Android at this time.
How is my data kept private?
All your safety data stays exclusively on your device. Contacts, vital signs, and location history never leave your iPhone. Kai has no cloud backend, no servers, no accounts, and no data collection. The Live Crime Map fetches public city data using your approximate location only. Never your contacts or vitals.
What happens if I accidentally trigger an alert?
Kai includes a short countdown before sending alerts, giving you time to cancel if it was a false alarm.
Is Kai free?
Yes. Kai Companion is completely free to download. Set up your trusted contacts and you are protected in under two minutes.
