Who's at the Door?
Knock. Peek. FLINCH. The free door-closing reaction game for iPhone, and the first built for iPhone Duo.
Free to download. Requires iPhone.
Someone is knocking. Peek through the door, read the caller, and decide in a split second: friend or foe? Close it on the burglar, the porch pirate and the raccoon. Never on grandma, the cookie scouts or the pizza courier.
Every knock is a gamble.
Your score is your FLINCH time: how fast you shut out the villains. The fastest flinch wins.
Simple to learn. Hard to put down.
A pure reflex duel with a daily reason to come back.
Made for iPhone Duo.
The wall and doorway stretch across both screens, with callers stepping out onto the street beyond. It plays just as well on every regular iPhone.
Knock. Peek. FLINCH.
Hear the knock, see who is outside, and close the door on villains before they pounce. Your reaction time in milliseconds is the score.
Flinch Three daily challenge
One seeded run per day. Every player gets the same callers and pounce timings, with rule twists like Quick Draw and Rogues' Day. Keep your streak alive.
Game Center leaderboards
Chase the fastest FLINCH, Best of 3 and the daily board. Climb the worldwide rankings and beat your friends.
Seasonal themes
A Christmas wreath and wallpaper in December, pasted-art trick-or-treaters at Halloween. The alien never takes a holiday.
Shareable postcards
Share a movie-poster postcard of whoever is standing in your doorway to Instagram, Messages or X.
Free to play
A small banner and the occasional interstitial. One optional in-app purchase removes ads forever. No energy meters, no paywalls on gameplay.
Fifteen friends. Six frauds.
Telling them apart is the whole game.
Friendly visitors
Nona, the firefighter, the cookie scouts, the dog and more. Flinch at any of them and the round is lost.
Villains who bluff
The burglar, porch pirate, missionaries, the wino, the raccoon and a UFO alien. Let them linger and they pounce.
How to play.
Wait for the knock.
The door cracks open and a caller steps into the doorway.
Read the caller.
Friendly faces are safe. Villains pounce if you let them linger.
Tap to close the door.
Your FLINCH time is recorded. Flinch at a friend and the round is lost.
Go for three, or keep going.
Three resolved knocks make a run. Endless mode lasts as long as your nerves do.
