Clockin Duo
Built for two. Only ever two.

The app where you’re both actually here.

Clockin Duo is a private room for two. Lock in on the same timer, watch the same frame, take your turn, and count down to the next time you’re in the same city - all in real time.

Free forever for the basicsNo feed, no followersOne price covers both of you
Everything happens live

Three things. All of them need two people.

Nothing here is a feed you scroll alone. Every screen assumes the other person might walk in at any second.

Running now
Lock In

One timer, two desks. Set a goal, hit start, and the whole screen goes dark except the clock - the same countdown runs on both sides, and a pause is a pause for both.

Paste a link and press play once. Either of you can pause, skip or scrub and it stays in step - with chat, reactions and an up-next queue sitting right under the frame.

Games

Four in a Row when you're both up. This or That and How Well Do You Know Me when you're not - every turn waits patiently for whoever's asleep, and the scoreboard never forgets.

Paired clocks

Their hour, always on screen, so you stop doing the arithmetic before every call.

Chat is never saved

Most apps for two people are for talking about later. This one is for doing something now, at the same time, and then getting on with your evening.

What it is for

Whoever opens the app first turns the dot green. Everything else starts from there.

Pricing

One price. Both of you.

FAQ

The things people ask first.

Is this only for couples?

No. It is for any two people who get more done beside each other - a friend you study with, a co-founder, a sibling, a partner. You pair with exactly one person, and that is who it is for from then on.

Can more than two people join?

No, and there is no way to add a third. One invite link, one seat, and it closes behind whoever opens it. Every screen is built around one other person being there.

How is the timer actually shared?

The clock runs on our server, not in your browser. You see the same second they do, either of you can pause and it pauses for both, and the session finishes on time even if you both close the tab.

What happens if only one of us is online?

You can still start a session on your own and they can join partway through. Games hold your turn indefinitely - take one now and they will find it whenever they next open the app.

Does Watch Together play the video itself?

It keeps YouTube playback in step between you. Some videos are set by their owner to refuse embedding anywhere - if the frame stays black, open it on YouTube and use the timer and chat alongside.

What happens to what we say to each other?

Chat only exists attached to what you are doing, and it is never written to a database at all - it lives on the server while one of you still has the screen open, and it is gone once you both leave. Reactions are not stored either. Nothing you write is sent to an AI service - there is no feature here that does that.

Who pays for premium?

Either of you. One subscription unlocks both accounts the moment it goes through, with no per-seat pricing and nobody needing to sign out and back in.

Do you show ads or build a feed?

Never. There is no feed, no followers and no algorithm. The product is the two of you, and there is nobody else for it to sell your attention to.

Pick a time. Be there together.

Set it up in under a minute. Invite one person - that’s the limit, on purpose.

Free to start. No card, no trial countdown.
