How it works

How the AI Health Coach works

STEP 1

Connect

Link your Garmin or Galaxy Watch account once โ€” activities, sleep and heart rate flow in automatically.

STEP 2

Two photos

One when you eat, one when you measure body composition. Everything else is automatic.

STEP 3

Cross-read

Weight, muscle, sleep and diet are read together. No scaremongering over a single number.

STEP 4

One line each morning

Delivered to your messenger: exactly what to do today, nothing more.

Data & Privacy

How we handle your data

The AI Health Coach starts as a private beta of about 30 users. The service is not a medical device and does not provide diagnosis or treatment advice. Health data is used only to provide user-requested coaching insights.

Data we use

Only what you consent to

Activity, sleep, heart rate, body composition and meal photos โ€” only data you explicitly connect or upload. Garmin integration follows the official Health API user-consent flow.

What we never do

No selling, no ads, no third parties

We do not sell health data, use it for advertising, or share it with third parties. It is never used for anything other than your coaching.

You stay in control

Disconnect or delete anytime

You can disconnect integrations at any time, and we delete your data promptly upon request. Details in our Privacy Policy.

About

About JYLAB

JYLAB is a one-person product studio in South Korea solving everyday problems with AI and automation. We ship a product only after the tool we built for ourselves becomes good enough.

The AI Health Coach started the same way: one person's automation for runs, body composition and meals is becoming a coach for everyone with the same problem.

Principles
Automated logging, data-driven interpretation, one-line conclusions. Health data is treated as sensitive information with data-minimization and purpose-limitation principles.
