iPhone

Getting four people into the same game takes fifty messages. Knock takes one tap. Tap Knock. Everyone in your squad gets a notification and answers right there — I'm in, in 30, or can't. Nobody has to open the app. Nobody has to read a thread. The lobby fills while you watch. You decide how many yeses make it a game — three of five is a game, and Knock knows that. The moment enough people are in, everyone sees it. WITHOUT OPENING THE APP Answer from the notification, the Lock Screen, the Home Screen widget, or the Dynamic Island. One tap, in place. NOTHING GOES STALE Knocks expire. A knock nobody answered quietly ends instead of sitting there for a day. Need a game later? Knock again. NOBODY GETS NAGGED A nudge reaches only the people who haven't answered — never the ones who already did. Mute any squad without leaving it. Set quiet hours and knocks arrive silently, waiting for you. SAYING NO IS FINE "Can't" is grey, not red. Declining a game isn't a failure, and Knock never treats it like one. No read receipts, no guilt, no streaks. NO CHAT, NO ACCOUNT Knock isn't a messaging app — the only text anyone types is their own name and an optional note of a few words. And there's no account: no email, no password, no sign-up. Open the app, pick a name, start knocking. No ads, no tracking, no analytics. Delete everything from Settings whenever you like.

A fix for a rare sign-out. • On some phones, opening Knock right after an update showed the welcome screen instead of your circles. It now waits a moment for your account and opens straight to them.
