SOS & Crash Detection — BRYKK Guide

The reason BRYKK exists. SOS, crash detection, and the safety plan are always free, always on, and built to work even when nothing else does.

Triggering SOS

The big red SOS button sits in the bottom-right corner of every BRYKK screen. To trigger:

Press and hold for 2 seconds (prevents pocket dials)
Your phone starts ringing 911 immediately
Every family member is silently alerted with your exact location, battery level, speed, and a navigate button
A red SOS pulse appears around your avatar on every family member's map
Family members hear a critical alert sound that bypasses Do Not Disturb and Focus modes — even if their phone is on silent

BRYKK does NOT call 911 for you automatically — that's your phone's built-in 911 dialer. You can cancel the call once you have signal, talk to a dispatcher, or hang up. The family alert fires the moment you press SOS, regardless of what happens with the 911 call.

Crash detection

BRYKK monitors your accelerometer at 20 Hz while you're driving. If a sudden impact above ~18G is detected (consistent with a serious crash), BRYKK:

Plays a loud alarm and vibrates aggressively
Shows a 10-second “Are you OK?” countdown
If you tap “I'm OK,” the alarm stops and nothing further happens
If you don't respond within 10 seconds, BRYKK fires a Crash Alert to every family member with your exact location, the nearest hospital, the nearest fire station, and a navigate button

This happens entirely on-device. No internet required for the detection itself — only for the family alert (which queues if you're in a dead zone and bursts when signal returns).

💡

On iPhone 14+ and Apple Watch Series 8+, BRYKK uses Apple's hardware Crash Detection framework when available. On older devices, it falls back to accelerometer-only detection with similar accuracy.

Safety Plan — for the family member receiving the alert

When you get an SOS or crash alert, tap the notification to open BRYKK directly to the affected family member's detail view. You'll see:

Their exact location on a map
Nearest police, fire, hospital, urgent care, gas station, auto repair — all real businesses found via Apple Maps near THEIR coordinates, not yours
One-tap navigate to any of those places from YOUR current location (so you can drive to them) or to send them step-by-step directions from THEIR location
Country-specific emergency number (911 in US, 112 in Europe, 999 in UK, etc.)
Translation button to send them emergency phrases in the local language

False alarms

False crash alerts happen — dropped phone, slammed door in the cup holder, hard pothole. The 10-second “I'm OK” window is designed to catch them. If you accidentally let it expire and the family alert fires, just open BRYKK and tap “Cancel SOS” on your own profile. The cancellation pushes to the family within seconds and the alert turns off everywhere.

What family members see

The SOS notification is impossible to miss — full-screen red, vibrating, ringing the critical alert tone. The family map shows a red pulse around your avatar. The status banner at the top of every BRYKK screen turns red and reads “SOS — [name]” until the alert is cancelled.
