Projects

The open-source applications and platform that make up the 5Health initiative — each one real, running, and built in the open.

Interface illustrations below are hand-drawn representations of our applications. We'll replace them with product screenshots as each app reaches general availability.

For healthcare providers

Objective, quantified signals

Tap rate, rhythm variability, and amplitude come from computer vision, using a method open to inspection.

Numbers you can track alongside what the patient tells you.

Review at your own pace

Patients record tests at home; you review the results and source video remotely, whenever it fits your schedule.

Trends, not just snapshots

Repeated tests show whether a patient's motor function is stable, improving, or declining over time.

That beats relying on a single in-clinic moment.

An assistant that will not counter-advise you

Nema helps patients keep up with medication, tasks, and assessments, supporting adherence between visits.

Read more
A deterministic rule checks the request before the model runs, so medical-advice or emergency intents are refused outright.

Open and auditable, hosted in the EU

NeuroChecker runs on an open-source, FHIR-based platform hosted in the EU, so you can see exactly how data is handled.

For patients and families

Test from home, in a few minutes

Finger tapping, rapid hand movements, and a short walk — no clinic visit needed for the test itself.

See your trends in plain language

Instead of a single number, you get a picture of how things change over weeks and months.

Share with the people who care about you

With your consent, a family member can follow your results and support you along the way.

An assistant that helps you keep on top of it

Ask Nema about your medication, tasks, appointments, or assessments, by voice or by typing.

It answers from your own data and runs on your phone, so the conversation stays there.

Your data stays yours

NeuroChecker runs on an open, EU-hosted platform with no ads and no tracking.

For healthcare providers

Review remotely, on your schedule

Patients record tests at home; you review results, video, and signal plots whenever suits you.

Video and data, perfectly in sync

Scrub through the recording and the signal plot's playhead moves with it, matching a moment to its value.

A single view across your patient list

See everyone you follow and their latest results at a glance, instead of switching between tools.

Correct and annotate with confidence

When automated analysis needs your judgment, you can adjust or add notes directly on the result.

Open, FHIR-based, EU-hosted

Medical Cockpit runs on the same open, auditable platform as NeuroChecker, with no proprietary lock-in.

For patients and families

A human check on automated results

If something in the automated analysis looks off, your clinician can correct or annotate it.

Your medication plan, kept current

Plan import lets your clinician keep your prescriptions up to date without re-entering everything by hand.

The same open, EU-hosted platform

The tool your clinician uses runs on the same transparent, EU-hosted infrastructure as your app.

Your results get a clinician's full attention

Medical Cockpit shows your clinician the same video and data you generated, not a simplified summary.

Faster, more considered feedback

Your clinician reviews video and signal plots side by side, so you're less likely to need a repeat visit.

For healthcare providers

Standards-based interoperability

Every resource is stored as FHIR R4, so it can be exchanged with other systems without custom mapping work.

Self-hostable, no vendor lock-in

The platform is open source — run it yourself, audit it, or extend it, on your own roadmap.

Data sovereignty by default

Hosting is EU-based, and the architecture keeps data within the jurisdiction your organisation needs.

Open identity, not a proprietary login

OpenID Connect handles authentication, so integrating an existing identity provider is a standard exercise.

A foundation you can build on

NeuroChecker and Medical Cockpit already run on it in production, so it's a proven base, not a theoretical one.

For patients and families

Your data stays in the EU

The platform is hosted in the EU under EU data-protection expectations, not scattered across servers you can't see.

Your data is portable, not trapped

Everything is stored using the open FHIR R4 standard, so your records aren't locked into one company's format.

Nothing hidden in how it works

The platform's code is open source and public, so how your data is handled can be checked by anyone.

One identity, used consistently

Standard OpenID Connect sign-in means your login works the same transparent way across 5Health's apps.

Built for the long term

Open standards mean moving your data or connecting a new system won't require reinventing your health record.

Why 5Health

Built openly, hosted responsibly

Hosted in the EU

Our platform and the data it holds run on EU-based infrastructure.

Open source

Every application and the platform underneath are open source, so the code is there to inspect, self-host, or build on.

Built with clinicians

We build and refine these tools with ongoing feedback from the clinicians and patients who actually use them.

Follow along as these projects grow

We're an early-stage, open-source initiative. Read more about who's building this and why, or get in touch.
