During a crash, ANGi measures forces transferred to your helmet, even when your helmet is not impacted by the ground. It then sends a countdown alert to your phone— if you're hurt and unable to stop the countdown, the app texts your GPS coordinates to your emergency contacts. Additionally, ANGi can notify your emergency contacts when you're heading out for a ride, and let them follow along in real time. ANGi is compatible with virtually all cycling helmets and is free to use. The ANGi sensor improves riders' safety and protection by offering an easy connection to help when it's needed most.
