The project

Read any lab report. Understand it in minutes, not appointments.

The situation
A lab report is a column of numbers with reference ranges from a different lab, a different country and sometimes a different unit system. Families keep them in WhatsApp threads and folders, and the only way to know what changed since last time is to ask a doctor for a second appointment.
What we built
Family health platform that lets users upload lab reports and get AI-decoded, plain-English explanations of every value, with an encrypted family vault covering up to 8 profiles. Ships 50+ calculators spanning heart, diabetes, pregnancy, mental health and kidney function, plus a doctor visit companion for pre- and post-visit summaries.
How it works for the business
Families upload lab reports and get plain-English explanations, with a shared vault for up to 8 profiles.
No longer done by hand
- Searching each flagged value one at a time
- Converting units by hand between labs
- Asking for an appointment just to have numbers explained
- Scrolling a chat thread to find the previous report

What the vault does to a column of numbers.

A report, decoded

Full blood panel · any laboratory

The site's own example panel, decoded in 8 seconds. Ranges follow WHO, ADA, NICE and ICMR guidance.

decoded

Marker	Value	Status	Plain English
Vitamin D (25-OH)	18 ng/mL	Low	Below the 30 to 100 range. Common, fixable, worth a word with a doctor.
HbA1c	6.2 %	High	Prediabetic band. Three-month sugar average, not a single bad day.
Fasting glucose	104 mg/dL	High	Impaired. Reads with the HbA1c, not on its own.
Haemoglobin	14.1 g/dL	Normal	Normal for age and sex.
Creatinine	1.1 mg/dL	Normal	Normal. Kidneys are filtering as they should.

Papa · HbA1c, last four quarters

The vault's own illustration: sugar climbing 0.8 points in nine months, across four reports from two different labs. Act before it crosses into diabetes.

The same task, twice

Before, and after.

Before

A report, the way most families handle it

Day 0
PDF arrives from the lab. Three values are flagged in red.
Day 0 · the snag
Family searches each flagged value. Finds ranges that do not match the report's units.
Day 1
Photos of the report forwarded to a relative who 'knows a doctor'.
Day 4 · the snag
Appointment to have the numbers explained. Ten minutes, no written summary.
Month 3 · the snag
Next report. Last one is somewhere in a chat thread. No trend visible.
Ongoing
Vaccines, medicines and bills tracked in memory, if at all.

Every report is read from zero, the trend is invisible, and the explanation is never written down.

After

The same report, in a HealthCalculus vault

Min 0
Report uploaded to the family vault, from any lab in any country.
Min 1 · automatic
Every value explained in plain English, colour-coded against the person's age and sex.
Min 1 · automatic
Conventional or SI units, chosen once, applied everywhere.
Min 3 · automatic
Trend drawn across every report ever uploaded for that family member.
Same day
Related calculator opened from the value itself: HbA1c to eAG, eGFR, ASCVD risk.
Ongoing · automatic
Vaccine schedule, medicine scans and hospital bill checks live in the same vault.

The explanation is instant and written, the trend is a chart, and the whole family's history sits in one place.

The real thing

Captured from the live site, not a mock-up.

HealthCalculus: the live site on a phone

Six life stages, one vault
Baby seekers, pregnancy, kids, men's health, women's health, elderly. Pick who the report belongs to and the product reshapes itself.
Fifty-seven calculators, mapped to the body
Mind, heart, liver, kidneys, blood sugar, cycle. A worry about the heart starts at the heart, not in an alphabetical list.
From confused to clear in four steps
Snap or upload, AI decodes, see trends, share or act. The site draws its own flow, and the vault below it shows a real HbA1c trend.
