Insights
Your data can tell a clearer story.
FATChat looks across trends in your own history and surfaces observations worth noticing. Insights are context — never diagnosis or dosing advice.
See how Insights workExample observations
BEYOND THE SCALE
Your weight has held steady for three weeks, but your waist is down 1.5" over the same period.
PROTEIN + ENERGY
On days you hit your protein goal, your energy averaged higher than on days you didn’t — something the two have in common, not proof one caused the other.
DOSE CHANGE CONTEXT
Symptom check-ins increased in the two weeks after your dose change compared with the two weeks before.

✓Explicit consent every time — nothing is processed by default
✓Clearly labelled an illustration, never a prediction or promise

Connected context
Designed to connect the health data you already have.
None of these connections are live yet. FATChat is being architected so Apple Health, Health Connect and select connected-health sources can one day add activity, sleep and body data as context — without ever replacing your control over what is shared. Until then, everything in FATChat is what you entered yourself.

Family Circles
Support without surveillance.
Family Circles are built for encouragement, not ownership of someone else’s health record. Each person has an independent account and decides what to share.

Questions
Simple answers to important things.
Is FATChat medical advice?
No. FATChat helps organize and explain patterns in your own data. It does not diagnose conditions or tell you how to dose medication.
Can my family see my health data?
Not unless you choose to share it. Family Circles are designed to be private and permission-based.
Does FATChat sell my health data?
No. FATChat is not designed around selling identifiable personal health data.
Do I need a wearable?
No. FATChat works with manual check-ins. Connected health sources can add context when those integrations become available.
Which GLP-1 medications can I track?
The product architecture is designed for medication and dose history rather than a single brand. Availability in the app will depend on the medication catalog at launch.
Your history. Your context.
Make your journey easier to see.
Start with simple daily tracking. FATChat helps turn that history into a clearer picture over time.
