After dark, the feed goes behind a shield that has no easy off switch, and a wind-down worth opening takes its place. Built on the four pillars of CBT-I, the gold-standard insomnia treatment.
No account. No cloud. Nothing leaves your phone.
Not a dashboard of your failures. A curfew that holds, and something better to do than scroll.
Pick your bedtime and the apps to put away. When the lights go out, they stay out, behind a shield that doesn't have an easy off switch.
Nine sleep protocols, from 4-7-8 breathing to a 22-minute sleep story. A breathing moon to follow, and a screen that dims itself as you drift.
The same gentle blocking runs your work hours and app limits. One tool for the whole day, not another thing to manage.
No account. No cloud. No analytics, no crash reports, no trackers. Your nights live on your phone. Uninstall and they're gone.
Reach for Instagram at 23:40 and you get the shield. Choose a wind-down instead. In the morning, an honest account of the night — how long the curfew held, not how well you slept, because we can’t know that and won’t pretend to.
Every one has a page: what it is, where it came from, and how good the evidence actually is. Including the ones where the honest answer is “not very”.
Nobody can fake a citation. Every technique in Lights Out names the research it rests on, so you can go and check it yourself. That is a harder thing to build than a testimonial wall, and a better reason to trust us.
