Your sleep window
Your first window comes from a week of your own nights. Every week it widens when you're sleeping through it and narrows when you're lying awake, never below a safe floor.
A six-week sleep program built around one thing: your sleep window. A 30-second diary each morning sets it, and it moves a little each week as your sleep settles. With sleep sounds, a phone lock for the hours you should be asleep, and a calm "can't sleep" mode for 3am.
Free forever: 20 sounds, diary, timer, one lock.
Program: $59.99/yr or $9.99/mo, 7-day trial.
Your first window comes from a week of your own nights. Every week it widens when you're sleeping through it and narrows when you're lying awake, never below a safe floor.
Rain, low drones and soft music, gapless and on a timer that fades out by itself. Twenty of them are free, and stay free.
Pick the apps that keep you up. In your window they open to a quiet screen that asks you to breathe for a minute first.
Your diary and sleep stay on your iPhone. No nightly score to worry about, just plain weekly trends and what seems to help you.
