The sickness story your household keeps living.

A light epidemiological tracker for the home. Log symptoms, watch how illness moves through your family, and bring real data to your pediatrician instead of your fuzzy memory.

Diary, not a diagnostic tool Built for messy households Data you can actually use

Three things, done well.

01 / Track
A diary that takes ten seconds.

Tap a family member, pick a symptom, set the severity. Designed to be done one-handed at 11pm with a feverish toddler on your lap.

02 / See
The story, drawn in data.

Timelines. Spread cascades. Heatmaps. Burden scores. The same illness logged five ways becomes a single picture you can read at a glance.

03 / Share
Real notes for real appointments.

Walk into the pediatrician with a printable summary instead of "I think it started maybe last Tuesday?" Your doctor can do more with more.

"By the third stomach bug of the year, I genuinely couldn't tell you whose vomit happened in which week."

A parent, somewhere, every winter

Avg. illnesses per child / year
8– 12

For kids under five. Many overlap, blur together, and never get written down.

Doctor visits with vague timelines
~70%

Most appointments rely on memory of what happened up to two weeks prior.

Time to log a symptom
10sec

If logging takes longer than the symptom itself, no one will actually do it.

People in your household
2– 8

Track partners, kids, the grandparent who visits, the nephew who started it.

Family Vector is a diary, not a diagnostic tool. It records what you observe and helps you see patterns in your own data. It is not a medical device. It does not diagnose, treat, or replace a clinician. If something feels wrong, call your pediatrician and bring your notes.
