Drowsiness often strikes without warning. DontSleep monitors your eye state through the front camera and alerts you the moment you start dozing off — helping you drive, study, and work safely.
Powered by Apple Vision framework, accurately detects open, half-closed, and closed eyes with millisecond responsiveness.
Combines prolonged eye-closure duration with PERCLOS metrics to catch both sudden danger and accumulated fatigue.
Three-level alarms — Remind → Warning → Emergency — grow stronger the longer your eyes stay closed.
One-tap switch to low frame rate and resolution to reduce heat and save battery; restores your custom settings automatically.
Dims the screen during detection, restores brightness when you look, and dims again when you look away.
A gentle voice reminds you to rest every full hour of continuous detection.
Tracks detection duration and eye-closure ratio, keeping up to 3 months of history to review your habits.
Adjust detection sensitivity, alert volume, frame rate, and resolution to fit any scenario.
