We are a technology company with a public health mission. Calm or Call gives every person in the UK instant, trustworthy guidance on whether their symptoms need A&E, NHS 111, a GP appointment, or safe home care — without waiting on hold or searching the internet for answers.
To help every UK resident make faster, safer decisions between A&E, GP, NHS 111, and home care — reducing unnecessary pressure on emergency services and ensuring that people who need urgent help get there sooner.
Medical uncertainty is stressful. Our goal is to replace that uncertainty with calm, clear guidance that you can trust — in under 60 seconds, with no sign-up, and at no cost.
¹ Estimate based on NHS England Emergency Department activity data and the Nuffield Trust analysis of avoidable A&E attendances.
The NHS is under extraordinary demand. For patients, this creates a difficult and stressful situation every time something feels wrong:
Calm or Call gives people an instant, reliable first step — before calling 111, before driving to A&E, before spiralling into anxiety:
We are a technology company — not a clinical organisation. But our triage logic is not invented. It is derived from, and cross-referenced against, validated clinical frameworks published by NHS England, NICE, the Royal College of GPs, and the British Thoracic Society. We do not guess. We follow the evidence.
Each triage pathway in the tool is reviewed by a qualified UK GP (MBBS, MRCGP) before publication. Clinical content is re-evaluated when relevant NICE guidance is updated. The tool's scope is intentionally limited — it does not attempt to cover presentations that require hands-on clinical examination.
Unlike global symptom-checker tools, Calm or Call UK is written specifically for the NHS care pathway. Terminology, recommended next steps, and escalation thresholds are calibrated to the UK system — A&E, 999, 111, Urgent Treatment Centres, and GP surgeries — not generic international equivalents.
Being a tech company means we can move quickly, iterate on evidence, and make the tool freely available at scale. It also means we hold ourselves to a strict standard: every clinical claim in this tool has a citable source.
Complete data anonymity
Your symptom answers and triage results are processed entirely in your browser. Nothing is sent to our servers. We have no access to your health information whatsoever. Sessions are 100% anonymous by design, not by policy.
UK GDPR compliant
We operate under the UK General Data Protection Regulation and the Data Protection Act 2018. Analytics are only activated with your explicit consent and collect no health information. You can refuse analytics and the tool works fully without them.
No data selling, ever
We do not sell, share, or monetise user data. We do not work with health insurers, pharmaceutical companies, or advertisers. Our tool is free because we believe access to health guidance should not be gated by ability to pay.
Complementary to the NHS
Calm or Call is designed to support NHS services, not compete with them. Our guidance always directs to NHS pathways — 999, 111, A&E, or GP — rather than to commercial alternatives. Reducing avoidable A&E attendances benefits everyone, including the NHS.
Evidence-based, not algorithmic guesswork
Every decision point in the triage tool maps to a published clinical protocol or NICE guideline. We publish our source references and update content when guidance changes. If we cannot cite a source, the content does not ship.
Honest about limitations
We are explicit that this tool does not provide a diagnosis and does not replace a doctor. We prominently display emergency guidance on every page. When in doubt, our recommendation is always to call 999 or seek professional care — never to rely solely on any app.

“The clinical pathways in this tool reflect how I think about triage in practice. For the presentations it covers, it gives patients a reliable framework for deciding whether they need A&E, a call to 111, or whether they can safely manage at home with monitoring. It doesn’t replace a consultation, but it’s a trustworthy first step.”
Important: Calm or Call does not provide a medical diagnosis and does not replace a GP, nurse, NHS 111, or emergency services. It is an informational and triage guidance tool only.
If you believe you or someone else may be in immediate danger, call 999 right away. Do not wait for, or rely on, any app or online tool in a life-threatening situation.
