When do you want to start winding down?

This is the time the countdown runs to. When it reaches zero the wind-down begins — half an hour to finish up, and then the screens go away. You can change either time whenever.

Lights out lands half an hour after the first time. The wake time is only used to tell Screen Time when to stop blocking.

What does "done for the day" look like?

Three small things. At lights-out the app shows this list, you tick them off, and the day is closed. Deciding them now, calmly, is easier than deciding them at 11pm.

This part is optional. Remove them all if you'd rather just have one button at the end. Either way you can change it in Settings.

Let it reach you

This is the part a browser tab can't do. Without this, the app is a countdown you have to be looking at.

Let's prove it works

A test notification, one minute from now. Lock your phone and put it down — that's the only way to know this really reaches you.

The on-screen counter will stop while you're away. That's normal — every browser freezes a backgrounded app's timers. The notification is sent from the server, so it arrives whether this app is open, closed, or force-quit. The counter catches up when you come back.

Nothing showed up? Check Settings → Notifications → Wind-Down, and make sure Wind-Down is allowed through your Sleep Focus.

One honest thing

This app can't block Instagram. No web app can — a browser has no reach outside its own tab.

What it can do is tell you it's time, keep the record, and hand you an exact Screen Time setup for your times. That's the layer that actually enforces anything, and it takes about ten minutes, once.
