Surv: Offline Survival Guide

Surv is a survival manual that keeps working when everything else stops.

Every guide, every scenario and every tool is compiled into the app itself. Nothing is downloaded, nothing is streamed, and there is no account to create. Turn on airplane mode and use the whole app — nothing changes.

IT STARTS WITH YOUR OWN NUMBER
Three questions — household size, water actually stored, days of food — and Surv computes how long you would hold, at the 3 litres per person per day used by civil protection plans. The number is arithmetic, shown with its method, so you can see exactly where it comes from.

TWO MODES, BECAUSE THERE ARE TWO MOMENTS

PREPARE — what you do with a year ahead of you.
Six kit lists with a reason written on every single line, an inventory that warns you 30 days before something expires, your family plan, your medical card, ten drills, and a readiness score that is deliberately hard to max out because 40 % of it comes from things money cannot buy.

IMPACT — what you do with ten minutes.
Pure black and tactical amber, text 12 % larger, every life-saving guide one tap away, guided triage in three questions, and the first ten minutes of each scenario. On an OLED screen the pure black background also uses less power.

WHAT IS INSIDE
• 61 written guides — stopping a bleed, CPR, choking, shock, burns, fractures, hypothermia, heatstroke, finding and purifying water, food storage and preservation, foraging, fire, shelter, navigation, signalling, security, sanitation, power, communication.
• 27 scenarios, each with before / during / after — earthquake, blackout, flood, wildfire, storm, heatwave, deep cold, water cut, tsunami, volcanic ash, chemical release, radiological event, epidemic, economic crisis, long-term collapse, no internet, cyberattack, civil unrest, armed conflict, automated systems failure, supply shortage, house fire, lost outdoors, stranded in a vehicle.
• 14 tools — a solar and celestial compass that computes true north from the sun's real position and stays right where a magnetic compass does not; the magnetic compass with bearing to a saved waypoint; your coordinates in two formats to read out to rescuers; waypoints and a trail map that needs no downloaded tiles; Morse SOS on the torch; a 3 kHz whistle tone; a CPR metronome; bleach dosing and boiling time by altitude; a ration duration calculator; a frequency and emergency-number reference; a field log; and a nearby link that messages other Surv phones within range with no network at all.
• A local decision engine. Type what is actually happening — "my child drank stagnant water and is vomiting" — and get the gesture to do first, with the guide it came from. It is a hand-written rule set over the guides in this app, not a language model: it suggests sourced guides. It may not cover every situation.

FREE FOREVER
Every life-saving guide, Impact mode, the guided triage, the compass, your coordinates, the SOS light, the whistle and the CPR metronome are free, with no account and no subscription. We do not charge someone who is bleeding.

WHAT SURV IS NOT
It is not a medical device. It gives no diagnosis, names no medicine and gives no dose, and it does not replace emergency services or a first aid course.
There is no artificial intelligence on board, and nothing here is generated.
It is not a street map: the trail map draws only your own points; carry a paper map.

PRIVACY
Your medical card, your waypoints, your inventory and your notes stay in a single file on this phone. No account, no cloud, no sync. Anonymous usage counters are OFF by default; otherwise the app only connects to Apple and RevenueCat for purchases.

Surv Pro unlocks the full library, the before-and-after phase of every scenario, the inventory with expiry alerts, waypoints, and all the tools. Monthly, yearly, or a one-off lifetime purchase.
