PlainRescue: Offline First Aid

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.
