About 5Health

An open-source healthcare initiative building patient and clinician apps on a FHIR-based, EU-hosted platform — early-stage and in the open.

At a glance

What it is: An open-source healthcare initiative, not a company pitch — built in public, one working piece at a time.
What is in it: Three projects: NeuroChecker for patients, Medical Cockpit for clinicians, and the platform they both run on.
Who is behind it: Initiated and sponsored by Patrick Palacin, who continues to drive it forward.
Where it works: German, English, French and Spanish, on EU-hosted infrastructure.
Where it stands: Early-stage and in active development. Both apps are in beta. No certification sought, and no clinical claims.

Why five

Five rings, five continents

5Health takes its name from the five inhabited continents, echoed by the five interlocking rings of the Olympic symbol. It is a reminder that healthcare should work the same way everywhere, not only in wealthy markets.

What we're building

NeuroChecker

The patient app for measuring movement at home.

Medical Cockpit

The clinician app for reviewing results and assessments.

5Health Platform

The standards-based backend both apps run on.

What we stand for

Open source

The code is public, so anyone can read it, question it, or build on it.

Data sovereignty

Hosting is EU-based and patients hold their own data.

Open standards

FHIR R4 and OpenID Connect — no proprietary formats, no vendor lock-in.

On-device AI

The assistant runs on the patient's own phone, not a cloud AI provider.

AI

How we use AI

CVMA

Turns an ordinary phone video into objective movement signals — tap rate, rhythm, gait.

Nema

Organises the day on the patient's own device, and refuses medical advice by a rule that runs before the model.
