Start a focus session together and you both watch the same countdown. Either of you can pause it, and it pauses for both. No camera, no strangers, nothing to book.
Free plan, no card needed. Premium is $4/month and covers both of you.
You set it up once. After that it is a time you both show up for.
Sign in with Google and send your invite. It works for one person, then closes.
25, 50 or 90 minutes, or any length up to three hours. Your goal shows on their screen too.
One countdown on both screens. Take five when it ends, then start the next round together.
Study partners, long-distance couples, co-founders, siblings. If there is one person you get more done beside, it is for the two of you.
Revise with the friend you already study with, not a stranger on a webcam.
How it works for youWork side by side across time zones, then watch something when the timer ends.
How it works for youSomeone you know, there while you work. Nothing to book and no camera to face.
How it works for youRounds you both keep, and a break you both take, on one shared clock.
How it works for youFocusmate matches you with someone from its community and needs your camera on throughout. Clockin Duo is for two people who already know each other.

For when the timer ends. Both are free, in the same app as your focus sessions.
Paste a YouTube link and press play once. Either of you can pause or skip, and it stays in step on both screens.
Take your turn whenever you open the app. The board waits for whoever is asleep, and the scoreboard remembers who won.
A green dot when they have the app open, and a ping you can send in one tap.
Their local time beside yours, so a different time zone stops being arithmetic.
Put down the date you next see each other, and it counts the days for you.
Whoever pays, the other person gets premium too. Cancel any time.
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.
Clockin Duo is for two people who already know each other: no camera, nothing to book, and one subscription covers both of you. Focusmate pairs you with a member of its community, on camera, usually in sessions you book ahead, and its free plan allows 3 sessions per week.
Yes. The timer, your standing times and your history all work before anyone accepts your invite, so you are not locked out while you wait for them - or if you never send one. Four in a Row is the only part that needs two, for obvious reasons.
No. There is no video or voice call anywhere in Clockin Duo. Your partner sees that you started, how long is left, and your local time, and that is enough to keep you both at it.
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.
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.
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.
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.
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.
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.
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.
Sign in with Google, send one link, and start when they join.
