PlainRescue: Offline First Aid

EqualInformation, LLC

About this app

When seconds count and there's no signal, PlainRescue gives you calm, step-by-step first-aid guidance you can trust — completely offline.

PlainRescue walks you through dozens of life-threatening emergencies one clear step at a time: CPR (adult, child, infant) with a built-in metronome, choking, severe bleeding, anaphylaxis, stroke (FAST), heart attack, seizures, burns, drowning, and many more. Every single step is backed by an authoritative citation you can tap and read — from the American Heart Association, American Red Cross, European Resuscitation Council, WHO, ILCOR, CDC, St John Ambulance, and the NHS.

Built for the worst moments:
• 100% OFFLINE — every protocol, citation, timer, diagram, and the voice guidance work with no signal. There is no network on any critical path.
• VOICE-GUIDED — PlainRescue can read each step aloud so you keep your hands on the person.
• ONE-HANDED & CALM — big targets, high contrast, dark-readable, minimal text per step.
• CPR METRONOME + TIMERS — keep the right compression rate and timing.
• ONE-TAP CALL — a Call Emergency Services bar with your region's number, always visible.
• CLEAR DIAGRAMS — labelled, public-domain illustrations on the key steps.

Learn before you ever need it:
• A Learn tab mirrors every emergency with in-depth, fully-cited study modules and practice quizzes — so the steps are already familiar when it matters.

For trained responders:
• Optional Clinician Mode (off by default) reveals a physician-grade clinical layer — doses, contraindications, differentials, disposition — all cited.

Your information stays yours:
• 100% on-device. No account, no servers, no cloud, no analytics, no tracking.
• An optional Medical Card (allergies, conditions, meds, emergency contacts) is encrypted on your device and never leaves it. PlainRescue can also point you to your phone's built-in Emergency information for lock-screen access by responders.

In your language:
• Follows your phone's language with English fallback. Available in English plus Spanish, Hindi, Arabic, Chinese, Russian, French, and Portuguese, with more added over time.

Completely free:
• PlainRescue is free for everyone — no subscriptions, no paywalls, no ads. Life-saving guidance should reach everyone.

IMPORTANT: PlainRescue provides guidance, not diagnosis. It is for educational and informational use and does not replace professional medical care. In an emergency, always call your local emergency services first.
