What your partner sees
One dot per day, today's first. Whether you showed up in your practice. The day you started together, and the last seven days behind it.
Kata Duo
One quiet dot a day.
Consistency is easier together. Duo is the smallest possible way to share it: one honest dot a day each, kept or not, with someone you trust. Never your logs, never your numbers, never a feed.
What it is
Shared form.
Not shared data.
Everything Duo moves between two people is one thing: whether the day was kept. That is the entire payload, by design, and it is the reason Duo can live inside an app that keeps your health on your own device.
- One dot, once a dayYour day counts as kept the moment you show up in Kata and log something, unless you close it yourself with an honest Off.
- Nothing else travelsNot your weight, not your meals, not your training, not your chats, not a score and not a streak. There is no number to compare.
- Up to five, on purposeFive duos keep it intimate: a partner, a training friend, a sibling. When you want a new one, you end an old one.
The quiet week
- Kept the day
- Not this time
- Nothing logged
How it works
Three steps,
then it goes quiet.
- Send the link
Open Duo in your profile and share a link, or let them scan the code straight off your screen. You can name them for yourself, and that name never leaves your device.
- They join
They open the link, sign in, and the two of you are paired. Their first dot lands the same day.
- You both just live
Nothing to write, nothing to maintain, no daily prompt. Each of you sees the other's last seven dots and the day you started, and that is the whole surface.
There is no code to type, no feed to scroll, and no way to message or nudge each other through Duo. The quiet is the point.
The boundary
What they see.
What they never see.
What they never see
Your weight, your meals, your training, your sleep, your mood, your blood work, your photos, your conversations with the coach, and any number at all. Your name too, unless you tell them: partner names are stored only on the device that typed them.
The dots
Four honest states.
The mirror is deliberately small, and deliberately not a verdict on you. Nothing here is red.
Kept the day
You showed up and logged something. This is the ordinary state, and it is generous on purpose: there is no threshold to clear.
Not this time
You closed the day yourself with an honest Off in the evening review. Only your own verdict can set this, never a score.
Nothing logged
A quiet grey. Nothing was logged, and nothing is claimed. Absence stays honest instead of being dressed up.
Invited
You sent a link and they have not joined yet. A dashed outline until they do, and you can withdraw the invite at any moment.
Who it is for
People who show up better
with someone watching.
Partners
You already share a kitchen and a bedtime. Sharing the form makes the small nightly decisions visible without turning them into a conversation.
Training friends
You train apart, but you want the week to count for both of you. One dot says more than a message neither of you would remember to send.
Anyone starting again
The hardest weeks are the first ones. Knowing that one person will see the dot is often exactly enough.
Duo is free, and it needs a Kata account so the two sides can find each other.
You stay in control
Yours to end, always.
End it, either side
Either of you can end a duo behind one confirm. The dots disappear from both sides right away.
Withdraw an invite
Sent the link to the wrong person, or changed your mind? Withdraw it before they ever join.
Hide without ending
Want the quiet back without the conversation? Hide a duo on your side. Kata says plainly that they still see your dot until one of you ends it.
Only ever the dots
The dot is the only thing that leaves your device for Duo, and the shared dots are dropped after about three weeks. Your logs, your numbers and your chats were never part of it.
Practice together.
Duo is free and lives in your profile. Start with Kata, then invite the one person who should see the dot.
