Knock is a small app, so this is a short page. If your question isn't here, write and you'll get a real reply.

My person's widget didn't light up.

Knocks arrive as a notification, so notifications must be allowed on their phone (Settings ▸ Knock ▸ Notifications). If they are inside their quiet hours, the knock arrives silently on purpose: their widget still updates, it just doesn't make a sound.

The code they gave me doesn't work.

Invitation codes are valid for up to 24 hours. If a code is unavailable, ask the sender for a new code or QR code.

Can I use Knock with more than one person?

One person is free, with everything that matters. The one-time unlock raises it to eight people and opens every emoji. There is no subscription and there never will be.

What happens if I unpair?

The connection is deleted for both of you, along with the streak and the encryption key. It cannot be undone, and you would have to pair again from scratch.

How do I block someone?

Settings ▸ their name ▸ Block. It unpairs you and stops them pairing with you again. They are not told, and it behaves for them exactly like an invitation that was quietly declined.

Knock didn't open FaceTime.

Both people need to have added the email or number their FaceTime uses. Knock asks the first time you knock, and skipping is fine. Without it, a knock still works perfectly well as a signal; it just won't place a call.

Will my streak survive a missed day?

Once a month, yes. Each calendar month gives you one grace day, so a single missed day won't undo a long streak. Two in the same month will, and with Knock Pro a run that broke can be brought back once a month.

I got a new phone.

Sign in to the same iCloud account and your people come with you. The encryption keys travel through iCloud Keychain, which Apple encrypts end to end.

Still stuck?
