FITA is an AI health companion: it reads your sleep, heart rate, HRV, and training load from your watch and rings, and tells you when to train and when to recover.

Your health isn't locked in one app. Through FITA MCP, any agent, from Claude to ChatGPT, reads your metrics, breaks down your workouts, and plans your day together with Fita. You decide who gets access to what.
Exhibition catalog · Vol. I
Not a fitness app. An editorial take on the body: every page is a state of the body, painted in watercolor, with Fita's living interface laid over it. One unified art system, not a collection of pictures.
The nightly architecture of recovery
Fita reads your sleep stages not as a list of minutes but as one whole night. Deep sleep, REM, and wake-ups come together into a picture of how well your body actually recovered — before you even open your eyes.
A quiet signal before the decision
“Go for it today” or “take it easy today” — a state that's hard to put into words. Fita picks up on it before you do and turns it into a clear answer for training, work, and rest.
How the body breathes through blood
Not “how many beats” but the story of a week's effort and rest. HR and HRV come together into a signal the agent can read with you — calmly, without the usual sports noise.
Sympathetic and parasympathetic
Tension and recovery are one rhythm, not two opposing modes. Fita tracks them together, so you don't mistake fatigue for weakness, or load for progress.
Effort and the body's response
Acute and chronic load on one line. Fita connects steps, heart rate, and sleep so effort stays smart — not a random spike on your training calendar.
Behind every widget and agent is a living body. The Physiology Collection is the brand's art system — the way a digital companion talks about itself without shouting like a fitness app.
Widgets, themes, and a chat that knows you. Try building your space right here — no install needed.

Questions and answers
FITA is an AI health companion. The Fita agent reads your sleep, heart rate, heart rate variability (HRV), stress, and training load from your smartwatch and rings, tells you when to train and when to recover, and builds a home screen of widgets around you.

Your health data and the agent’s memory are stored on your device. To answer, Fita sends the necessary context to the server in the selected region and the connected AI provider. See the Privacy Policy for details.
It's a way to give AI assistants like ChatGPT, Claude, or Gemini access to your metrics. Access opens only with your permission, and you decide who sees what.
An honest empty state. Fita doesn't fill in made-up or zero numbers in place of measurements that don't exist.
No. Fita's suggestions are informational, are not a diagnosis or prescription, and don't replace a doctor's consultation.
