Surv Downloads & RevenueSurv: Offline Survival Guide · App Store

Surv is an offline survival and first aid guide for people preparing for emergencies, outdoor trips or power outages. Every guide and tool is stored on the iPhone, so it keeps working with no signal and no account.

Surv Pro, a subscription or a one-time purchase, is required to open the full library and the tools after the welcome.

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.

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, the urgent guides one tap away, guided triage in three questions, and the first ten minutes of each scenario. On an OLED screen it also saves most of your battery.

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; 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.

ALWAYS OPEN, WITHOUT A PURCHASE
The SOS light, the emergency numbers and the CPR metronome stay accessible without a purchase, as do the first guide you read and everything you write yourself.

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, you
