When do you want the day to end?
Pick the time you'd like to be off your phone. Not the time you'd like to be asleep — the time the screens go away. You can change it whenever.
The wake time is only used to tell Screen Time when to stop blocking.
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.
Add to your Home Screen first
On iPhone, notifications only work from an installed app — never from a Safari tab. It's Apple's rule and there's no way around it.
- Tap the Share button at the bottom of Safari.
- Scroll down and tap Add to Home Screen.
- Open Wind-Down from your Home Screen and come back to this step.
You'll get a quiet notice as your wind-down starts, and one when it's time. Nothing between, nothing after.
Skipping is fine — the countdown still works when the app is open. You can turn this on later in Setup.
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.
