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. No network on any critical path. • Voice-guided — PlainRescue reads each step aloud so you keep your hands on the person. • One-handed and calm — big targets, high contrast, dark-readable, minimal text per step. • CPR metronome and recheck timers to keep the right rate and timing. • A Call Emergency Services bar with your region's number, always one tap away. • Clear, labelled diagrams 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 Apple's Medical ID for lock-screen access by responders. IN YOUR LANGUAGE • Follows your device 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. 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.
