Drowsify

Drowsify helps keep you alert behind the wheel by watching for the earliest signs of drowsiness — and sounding a loud alarm before a moment of fatigue becomes dangerous. Mount your phone at eye level and Drowsify uses the front camera to monitor your eyes in real time. The moment your eyes start staying closed too long or your blinks slow down the way they do when you're getting tired, a loud alarm and vibration jolt you back to attention. HOW IT WORKS - Tracks how long your eyes stay closed over time (a proven fatigue measure used in real driver-monitoring research) - Detects the slow, heavy blinks that signal drowsiness - Sounds a loud alarm — even with your phone on silent — until you're alert again BUILT TO BE ACCURATE FOR EVERYONE - Calibrates to your eyes with one tap - Works even if you wear glasses - Adapts automatically as lighting and conditions change PRIVATE BY DESIGN - All face detection happens right on your device - No video, images, or face data are ever recorded, uploaded, or shared ADJUSTABLE TO YOU - Choose how sensitive the alarm is - Turn sound and vibration on or off IMPORTANT: Drowsify is a driving aid, not a substitute for rest. If you feel drowsy, pull over somewhere safe and rest. Never rely on any app to keep you awake while driving.
