Protection That Doesn't Require You to Act
In a serious car accident, you may not be able to reach your phone. Trust Circle's crash detection uses your phone's sensors to detect the sudden deceleration and impact patterns consistent with a vehicle collision. When a crash is detected, the app automatically sends emergency alerts to your trusted circle with your exact GPS location.


How Crash Detection Works
Trust Circle monitors your phone's accelerometer and motion sensors while you're driving. If the app detects a pattern consistent with a collision — sudden deceleration, impact force, and stopped motion — it triggers a countdown timer. If you don't respond within the countdown (meaning you may be incapacitated), your trusted circle is automatically alerted with your location and a notification that a potential crash was detected.
Smart, Not Annoying
False alarms are frustrating. Trust Circle uses advanced algorithms to distinguish between a real collision and everyday events like dropping your phone or hitting a speed bump. The countdown timer also gives you a chance to cancel if the detection was triggered accidentally. The system is designed to be reliable when it matters and invisible when it doesn't.
A Safety Net for Every Driver
Whether you're a new driver, a daily commuter, or a parent with teens on the road, crash detection adds a critical safety layer. Combine it with Trust Circle's other features — live video, location sharing, and SOS alerts — and you have comprehensive protection for every mile you drive.
Frequently asked
How does crash detection work?
Trust Circle uses your phone's motion sensors to detect impact patterns consistent with a vehicle collision. If a crash is detected, the app triggers a countdown and, if you don't respond, alerts your trusted circle.
Will it drain my battery?
Trust Circle's crash detection is optimized for minimal battery impact, using efficient sensor monitoring that runs in the background without significant drain.
Can I turn off crash detection?
Yes. Crash detection is a configurable feature that you can enable or disable in your Trust Circle settings at any time.
What if it detects a false crash?
A countdown timer appears before any alerts are sent. Simply dismiss the countdown to cancel. Trust Circle also uses smart algorithms to minimize false positives.
Does it work with motorcycles or bicycles?
Crash detection is primarily calibrated for vehicle collisions. However, severe impacts while cycling may also trigger detection. The countdown timer ensures you can cancel false alerts.
Is crash detection available on all phones?
Crash detection is available on iPhones and Android devices with accelerometer and motion sensors, which includes the vast majority of modern smartphones.
