Drive Sentinel helps you stay alert at the wheel. Many accidents happen from driving drowsy. Drive Sentinel uses your Apple Watch and iPhone to quietly watch for signs of fatigue while you drive — and warn you in time to take a break. How it works, in two stages: • Your Apple Watch analyzes your pulse and its variability. When your physiology starts showing signs of sleep, a first signal fires. • Your iPhone, if mounted in view, confirms with the camera by checking your eyes (blinking, yawning) before alerting. Fewer false alarms. Built not to distract: • Starts on its own as soon as it detects you're driving. • Works quietly and only alerts you when needed — with haptics, sound, and voice. Private by design: • All analysis happens on your device. No video or health data is ever recorded or sent anywhere. Important: Drive Sentinel is an assistance aid, not a guarantee. It is not a medical device and does not replace responsible driving or rest. If you're tired, stop and rest.
