The day starts with a chat
One line from Kata opens the morning: what today holds, and the one thing that matters most. No forms, no dashboards.
Personal Health Coach
Just talk.
The system
does the rest.
Tell Kata about your day by chat, by voice, or with a photo. It becomes your plan, your numbers and your next move. Yours alone, and it stays that way.
Feels like texting a coach.
Works like a complete system.
Made for the day
Your day becomes a ritual.
One short conversation carries the whole day. Behind it, Kata keeps your numbers, your memory and your plan in order, so you never have to.
One thread for the whole day
Wake, meals, training, sleep: whatever you mention lands on one timeline. Logging feels like talking, because it is.
Everything finds its place
Whatever you say and whatever you connect is remembered, sorted and charted. You lift nothing.
Intelligence that plans your day
The AI layer reads your recovery, sleep and training from WHOOP and Apple Health, then turns them into a few clear recommendations for today and schedules the reminders that keep them on track. Refresh them anytime.
The name
Practice the form. Become it.
In Japanese budo, a kata (型) is a form you repeat until it stops being effort and starts being you. Not another tracker to feed: a form for your day. The system holds it, you practice it.
- One form, dailyMorning stack to evening review: your whole day in one flow, not six apps.
- Phase-basedCut or Build set the targets. The system does the daily arithmetic.
- Repetition over motivationStreaks, routines and a day score that reward showing up, not perfection.
Inside Kata
You talk. Kata takes care of it.
Chat, voice or a photo. Kata handles the data and the tech behind it, so your side stays simple. Rather do it yourself? Switch to data mode and enter everything by hand.
You can also ask Kata anything about your data, in any moment, for any goal, whatever phase you are in. It knows all of it.
Honest comparison
Why not just ChatGPT & Co?
Fair question. General AI is brilliant, and tracking apps are thorough. Kata is what neither can be alone: a coach that knows your numbers, inside a system that remembers you.

They remember conversations. Kata keeps your health in order: one coach, your numbers, your day, saved only when you say so.
From daily practice
People keep telling us the same thing.
“When you are busy just dealing with life, the first thing you drop is yourself. I started paying attention again and ended up with five apps and five subscriptions. Now it is one place, it knows me, and what it reminds me about is my day, not someone else’s.”
“I work late and I work a lot. I tried the apps, then I built my own trackers with AI, and I was never consistent with any of it. This one sits in my pocket and holds the thread whether I open it or not.”
“I travel constantly and my routine used to fall apart every time. Now it does not matter where I am, or whether I logged anything while I was there. I can always catch up.”
“I took supplements for years without really tracking whether I took them. I never got to see what they did to my sleep or my training. Now I can see it.”
“It is genuinely surprising what comes out of just talking about your food, your drinking, your training and your supplements every day. The rest is handled, and it tells me what to change and why.”
“A coach I can just talk to while I am out, with my Apple Watch and my WHOOP feeding it. One place, and it reads the data back to me properly.”
“The combination of coaching and motivation is what got me. I went all the way in: put my blood work in, gave it everything the other tools already knew about me. It is finally in one place.”
