The questions are the product

Change the room. Watch the questions change.

Nothing is shared between rooms. Every question is written for one room and one tone, and used nowhere else.

iPhone only

Nobody sees a single answer until everyone’s in.

Send one question into a group chat and it becomes a round. Everyone answers privately. When the round closes the chat votes, and the names come out with the answers.

The reveal: the winning answer named, with its vote count
  • Everyone in the thread answers and votes free. Only the person asking needs Pro.
  • Ask the day’s question, or write your own and send it.
  • Two people skip the vote and go straight to the reveal.
  • No account and no server. The whole round travels inside the message.
  • Nobody in the room? Start a round from anywhere and let the chat play through the night.
  • Everyone playing needs Catalyst installed.

Free. Answering is always free, for everyone in the chat.

Four tones

Same room, four different nights.

Chill

Easy, warm, low stakes.

If you could be amazing at one totally useless thing, what would you pick?

Strangers

Deep

Honest and reflective.

What’s something I used to do for you that you miss?

Couple

Funny

Roasts and chaos, lightly.

Roast me in exactly one sentence.

Friends

Bold

Daring and playful.

What was the first thing you noticed about me before I said a single word?

First date

Bold is only offered in rooms where it belongs. It never appears at the family table.

The deal

Three taps. No setup, no account.

Nothing to sign up for and nothing to load. Every question is already on your phone, so it works with no signal at all.

01

Who’s here

Two of you, a small huddle, the whole room. Then the room itself.

02

What kind of night

Chill, Deep, Funny or Bold. The tone changes the whole hand.

03

The hand

Read one out loud. Swipe for the next. Deal again when the room changes.

1,003 questions that are never dealt

A third of the app is behind a deck.

Deck questions are written for one deck and used nowhere else. They never enter the pool, and no amount of dealing will turn one up.

After Midnight

When the night gets honest

What’s the dream you only let yourself think about this late?

Roast Session

Affectionately brutal

What’s the story this group will still be roasting you about in twenty years?

Sibling Rivalry

You have the right to roast

What lie did we tell our parents growing up that they still believe today?

Most Likely To

The group decides

Who here is most likely to start a fight with a self checkout machine and lose?

Fifty decks, around 20 questions each: Date Night, Best Friends, Family Ties, The Big Questions, Truth or Dare, Office Icebreakers, Never Have I Ever, Road Trip, Happy Hour, Holiday Chaos, and forty more.

The free part

One hand a day. Free, and it stays free.

A hand a day, any room, any tone that room offers. No account, no card, nothing to sign up for. Most nights that’s the whole night. The nights it isn’t are the ones you’ll be telling people about.

Catalyst Pro

For the nights that run long.

Unlimited hands

Deal again the moment the table wants more. Switch rooms when the group splits and deal again for whoever’s left on the couch.

All 50 decks

Stop choosing. Roast Session when someone’s earned it. After Midnight at 2am. The Big Questions when it’s finally time.

Your color, kept

The app opens in the color you left it in. In a group chat, that color is the card everyone in the thread receives.

You’re the one who sends it

Start a round in any thread. Everyone else answers and votes free. Pro is only for asking.

Monthly, annual, or once. Lifetime is a single purchase that never renews. Prices are whatever the App Store shows you.

Your first hand is dealt before you’ve typed anything.

Make it yours

Fifteen palettes, or mix your own.

Tap a color and the whole app repaints: cards, buttons, deck backs.

Before you tap

The things people ask first.

Isn’t this just a list of icebreakers?

No question is shared between rooms. The library is split by who’s there, how many of you there are, and the tone. Each question is written for exactly one of those. The card a couple gets on a Deep night was never meant for anyone else.

What if there’s nobody around right now?

Send a question into a group chat instead. Everyone answers on their own time, nothing is revealed until the round closes, and answering is free for all of them. Or open a deck and save it for Friday.

What does Pro cost, and will it keep charging me?

Monthly and annual both renew until you cancel. Lifetime is a single purchase that never renews. Whatever the App Store shows you is the price. There is no other checkout.

What do I actually get without paying?

One hand every day, in any room and any tone. Plus answering and voting in any group-chat round someone else starts. Pro is for dealing more than once, opening the 50 decks, and being the one who starts the round.

Will it get awkward with family or coworkers?

You set the tone before anything is dealt, and Bold is only offered in rooms where it fits, never at the family table or with coworkers. The work decks are written to stay work-safe.

Am I going to run out?

3,110 questions. 2,107 get dealt into hands, and 1,003 more are written for one deck each and are never dealt at all.

Light the room

Somebody has to ask first.

Free. Your first hand is dealt before you’ve typed anything.
