What Lights Out does

Focused bedtime tooling. No cloud account required.

Smart Bedtime Timers

Preset or custom countdowns. Save profiles for different nights. Quick-start from the tray, keyboard shortcuts, or the cockpit dashboard.

Gentle Wind-Down

Guided breathing ritual, warm screen shift, ambient soundscapes, and smart light dimming. Bedtime without the cold-stop feeling.

Automatic Shutdown

Shutdown, sleep, hibernate, or restart — with an emergency cancel always available. Force shutdown only when you explicitly ask for it.

Morning Proof

Receipt-style confirmation of every run: what happened, when it happened, and whether you cancelled or followed through. Honest results.

Streaks & Sleep Score

Track your bedtime consistency with a streak counter, achievements, and a sleep score that only counts real completed nights.

No Cloud Account

Everything runs locally. No sign-in. No telemetry. Your bedtime data stays on your machine.
