Chapter 01
Measure
Four ways to take a reading — camera, face, keypad, or scan.
Issue 01 · Autumn 2026
One private health graph
10 apps. 10 subscriptions. Nothing connects them. HealthGraph does.
Check your pulse with your camera. Log meds, meals, sleep, and cycle. Ask your own data what it means. One graph holds it all, on your phone instead of our servers. Free to start, free to keep.

Measured on your phone, joined into one graph: nights explain mornings, meals explain afternoons
Sixteen capabilities, four domains. Whatever you measure lands in the same graph — and stays there, even if you switch apps.

Chapter 01
Four ways to take a reading — camera, face, keypad, or scan.
Chapter 02
Entries become relationships. Relationships become a next step.
Chapter 03
Plans, documents, nights, cycles — ordered and exportable.
Chapter 04
One tap, and the day turns in the right direction.
03Priority engines
Seven priority engines. Each one reads what you actually logged and shows what changed — no score, no verdict.
Chapter 03
You pick your focus areas during setup, and any number of engines can run side by side. Every engine compares the last seven days against the seven before. A value you never logged stays missing: it is never quietly turned into a zero, and never into a grade.
Reads the nights you logged, with bedtime and wake time when you enter them.
Shows how long you slept on average, one honest line about bedtime consistency, and this week against last week.
Reads the weight in your profile.
Shows that number and where it came from. No trend line from a single point — one value has no baseline, so it does not get one.
Reads check-ins, logged doses, substance entries, cycle entries and camera measurements.
Shows how many days you logged something, your streak, and adherence — three separate lines, never blended into one score.
Reads the activity sessions you logged, with their durations.
Shows sessions, active minutes, and the calories and distance you entered yourself.
Reads the meals you counted and the calories a food scan estimated.
Shows meal counts and scanned calories as they are, plus targets you set yourself. Targets are goals, never prescriptions.
Reads your mood, energy and stress ratings from one to five.
Shows each rating on its own scale of five. They are never averaged into a single mood score.
Reads your camera pulse and face pulse measurements, plus HRV when the capture was clean enough for it.
Shows heart rate, HRV, and how much of it was reliable. Camera and face readings stay labelled; they are never silently merged.
04The graph
Not a list. A typed, time-aware structure — and every path through it is written down in advance.

shared reference — queries end here
01 · No causal edges.
CAUSES, TREATS and NEXT are not in the vocabulary at all. The graph records what sat next to what and when — never what caused what. Any answer that says “because” is doing more than the data allows.
02 · Terminal labels.
Concept, Medication and AnatomicalStructure are shared reference data. A query may end there but never travels through them, so one patient’s graph can never be walked into another’s.
03 · Assertions, not assumptions.
A negated, hypothetical, historical or family-attributed mention stays an assertion. Only confirmed facts are allowed to become a condition you carry.
AppendixAnd the three systems that feed it.
Where the records come from before they reach the graph — and how they stay checkable.
Scanned documents are split into passages and indexed, so an answer can point back to the exact lines it came from.
Every claim Sanotts makes carries a citation you can open. If the text does not support the claim, the citation is dropped instead of kept.
Lab reports and prescriptions are read by a document model and turned into fields you can search.
A photographed lab report becomes a date, a value and a unit — searchable, instead of a PDF you scroll through.
Male and female body shells are generated by this project and ship inside the app. Finer organ models download once, then work offline.
The shells need no download and no licence. Tap a zone and the graph answers with your data for it.
05The app
Three screens, one graph

Nutrition, sleep and the shape of the day sit on one card — a single page you read in the morning and then dismiss.
Sixty seconds of stillness, one finger in front of the lens. Pulse and HRV, without a wearable, without the cloud.
Weeks, months, years — plus correlations you build yourself between two metrics.


These screens are not mockups. Everything you see runs on your device — the app is the graph, and the graph is the app.

Get early access07A day
Not a dashboard you admire. A rhythm you barely notice.
Your alarm speaks. You answer half-asleep: slept badly, shoulder aches. Logged before your feet touch the floor.
Breakfast barcode, one scan. Oats, again. Your phone remembers the product. No signal needed, no typing.
The midday dose was due at 13:00. One tap notifies your sister, straight from your phone. She texts back: proud of you.
Finger on the camera, sixty seconds. Heart rate, HRV, done, while the pasta water boils.
The graph shows it plainly: short nights cluster before heavy days. Tomorrow you protect the evening. That is the whole trick.
Five moments. Not one of them feels like data entry.
08How it works
Three moves. Sixty seconds at a time.
Pulse, meals, meds, sleep, symptoms, captured by camera, barcode, voice, or a ten-second tap. Whatever costs you the least effort wins.
Everything lands in one graph. Nights explain mornings, meals explain afternoons, meds explain the flat weeks. Correlations surface on their own.
Seven priority engines turn patterns into what changed, so the next move is yours to pick. Refill before you run out. Protect the evening. Call your sister. Small moves, compounded.
09Privacy
Device-first by design. Your data never has to leave your hand to be useful
Camera pulse, face pulse, and the health graph itself live on your phone. The cloud is a backup you control, not a business model.
Cached files are encrypted at rest and wiped the moment you log out. Lose your phone and your health history does not go with it.
DSGVO-compliant, export and deletion in one tap. Your health data is never sold. We would have to have it first, and we do not.
Full export in open formats, full deletion with no dark patterns. Leaving is easy, which is exactly why you will not want to.
The principle
Selling health data would be a business model that owns data. We own none.

BAppendix · The team
We're two independent builders brought together by a shared interest in AI, healthcare, design, and everyday technology that means something.

One of us works with AI, software, healthcare systems, and knowledge graphs. The other shapes how technology feels to the people using it. Neither of us comes from healthcare, and we don't claim to be medical professionals. We saw a problem worth exploring, so we learned, experimented, and built our way toward a possible solution. HealthGraph grew from that journey.
Health information is everywhere, but rarely connected. Reports live in one place, prescriptions in another, and fitness, sleep, and food each in an app of their own.
Your health isn't fragmented. Your records are.
We don't believe the future of digital health is ten apps for ten parts of your life. It's one connected experience: records, medications, measurements, daily habits, and your history, joined into a clearer picture over time.
Not another app for the collection. One place where your health comes together.
“Your health is a connected story. Your technology should understand it that way.”
CAppendix · Answers
100 questions people ask before they switch. Each one lands here, answered from the app itself.
DAppendix · Questions
Asked by people who have been burned by health apps before.
No. HealthGraph is a wellness companion, a clearer mirror, not a doctor. It never diagnoses, stages, or treats anything. Anything that looks clinical belongs in front of your actual clinician, and the app says so wherever it matters.
On your phone first. Camera and face pulse never leave it; cached files are encrypted and wiped on logout. Export or delete everything in one tap, any time. DSGVO-compliant, never sold.
Daily logging and check-ins, medications with dose tracking, the timeline, 3 meal scans and 2 AI messages a month. Free means free. The paid tiers unlock unlimited lenses like camera pulse, the full graph, and voice features.
No. Your fingertip on the camera gives heart rate and HRV in sixty seconds; a short selfie video does the same for face pulse. Wearables are welcome guests, never requirements.
You invite someone you trust and pick which medications they watch. If a linked dose is missed, you tap once and your SMS app opens with the message ready. Nothing is ever sent automatically. Your tap is the consent, every time.
Early access runs on Android, in English and German. Your invite email tells you exactly what to install.
Press approval
Leave your name, email and city. We email your early-access invite with the free trial, usually within days, never into a spam folder you will never check.
