What you can do

Surv: offline survival guide and emergency preparation

A survival manual that works with no signal: first aid, water, shelter, emergency scenarios and field tools, all on your iPhone. Prepare your kit today, and find the right step fast when the power or the network goes down.

Guides that work without a network

Guides and scenarios work offline. Life-saving guides, the first ten minutes and the “during” phase of each scenario stay free. Surv Pro unlocks the full library and complete scenarios. Check access to the content you need before a trip.

Your household, ready in advance

List your supplies, keep an inventory, and write down your family plan and your medical card. They are stored only on your iPhone.

Field tools

The standard compass, coordinates, SOS light, whistle and CPR metronome are free. The solar compass and saved waypoints require Surv Pro. Keep physical backups: a phone can break or run out of battery.

Surv is a reference tool, not emergency services or medical advice: in an emergency, call your local emergency number first. Some in-app guides are not yet translated into every language shown on this site.

Questions

Can I use the survival guides offline?

Surv stores its guides and scenarios on the device. Review the content and tools before a trip, and keep physical backups because an app needs a working, charged phone.

Does Surv replace emergency services?

No. It is a preparedness and reference app. Follow instructions from local authorities and contact emergency services when needed.

Does Surv drain the battery?

No. It does nothing in the background: GPS runs only while a screen that needs it is open. Impact mode uses pure black, which saves battery on an OLED screen.

Where is my medical card or family plan stored?

Only on your iPhone, in the app’s private storage. There is no copy elsewhere, so keep an encrypted device backup if you rely on it.

The compass points the wrong way. Why?

A phone compass is a magnetometer, disturbed by metal, speakers or magnetic cases. Move away from metal and wave the phone in a figure of eight. The solar compass in Tools computes true north from the sun.

Can I test the offline mode before a trip?

Yes. Turn on airplane mode and use the whole app; every guide, scenario and tool is compiled into it.

What does it cost?

The App Store and the app show the current price and available purchases in your local currency before confirmation. Trial availability depends on the offer and your eligibility. A free download does not mean every feature is free.

Is the app available in my language?

These are translated website pages. Check the Languages section of the App Store listing for the app itself. Some content may use a different language.

How do I manage a subscription?

On iPhone, open Settings, tap your name, then Subscriptions. Select the app to review or cancel an active subscription. Deleting the app does not cancel a subscription.
