Docs
Welcome to Kata.
Kata is your personal health coach. You talk to it, and one place holds your whole day: training, food, water, sleep, supplements, weight and progress. These docs cover every part of it.
The idea
In Japanese budo, a kata (型) is a practiced form: a sequence you repeat until it stops being effort and starts being you. Kata the app works the same way. You do not fill out forms or dig through databases; you tell Kata about your day, and the system holds the form for you: your goals, your numbers, your rhythm.
How it fits together
In front is the chat: a conversation that understands you, proposes what to save, and answers with your own numbers in mind. Behind it, everything you say lands in the right place: the Today screen arranges your day, the trackers keep your streaks, and the trends that matter draw the bigger picture on your Profile.
What you tell Kata stays with you: your logs, chats, memory and photos live on your device. The details are in Your data.
Where to start
