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.
Ratings & Reviews
Games
Your squad keeps a short list of what it actually plays. A knock can name one, so everyone knows what they're saying yes to — on the notification, in the lobby, on the widget.
A large widget
The whole squad on your Home Screen: who's in, who's on the way, who hasn't answered yet. Answer without opening anything.
Knocks that finish themselves
Half an hour after your squad goes ready, the knock closes on its own. No more lobbies left open all evening.
