Survival knowledge that works when nothing else does.
A 6,600-book survival library, AI photo-ID, first aid, navigation and off-grid comms — all running on your phone with no signal, no servers, no tracking. Download once. Ready forever.
Real on-device AI — not a checklist that needs a connection.
Most "survival apps" are static lists or cloud apps that die the moment the grid does. Power Prepper runs a genuine AI brain locally, so the smartest tool in your kit is the one that needs nothing at all.
Offline AI answer engine
Ask any survival question and get an answer synthesized from thousands of real books — with citations — entirely on your device.
A 6,600-book library
Distilled from a 7,000-volume preparedness corpus — water, fire, medicine, foraging, navigation, defense, power, and more, fully searchable.
Private by architecture
No account, no sign-in, no tracking. After the one-time download the library, AI and photo-ID run entirely on your phone, and we run no server that receives what you enter. The few things that do go out — a news refresh, a weather-alert lookup you switch on yourself — are listed plainly in the privacy policy.

Built on a library nobody else has.
The intelligence comes from a curated 7,000-volume, 25 GB preparedness corpus — compressed onto your phone and made instantly searchable by on-device AI.
- Answers from real booksEvery response is grounded in source material, not invented — with the titles it drew from.
- Safety-first by designIt will never tell you a plant or mushroom is "safe to eat" or call a venomous creature harmless. It surfaces hazards, not risky verdicts.
- No connection, no compromiseThe full capability is there at the bottom of a canyon, in a blackout, or three days into the backcountry.
Set it up once on Wi-Fi. Never need a signal again.
Install & download
Get the app, then do a one-time ~6 GB download of the library and on-device AI over Wi-Fi.
Go anywhere
Put the phone in airplane mode if you like — everything keeps working with zero connectivity.
Ask, identify, act
Search the library, ID a plant, follow a protocol, find your bearing — instantly, offline, every time.
Fully bilingual — English & Spanish.
Region-aware voice and text for Spain (es-ES) and Latin America (es-419) — the first serious offline prepper app built for Spanish speakers, not just translated for them.
Buy it once. Own it forever.
Free to download. One in-app purchase, once, after the trial — then it's yours. No subscription. No ads. No data harvesting.

Good to know.
Does it really work with no internet?
Yes. After a one-time download over Wi-Fi, the AI, library, photo-ID and tools all run entirely on your device. You can keep it in airplane mode permanently and lose nothing.
How big is the download?
About 6 GB, downloaded once over Wi-Fi. That's the cost of carrying a real survival library and AI offline — and you never have to do it again.
Is my data collected?
No. There's no account, and we run no server that receives what you enter — your searches, photos and notes stay on your phone. The only things that go out are ones you turn on yourself, like a news refresh or a weather-alert lookup (your coordinates go to the US National Weather Service, never to us). It's all listed in the privacy policy.
Is this medical or safety advice?
No. Power Prepper is an educational reference and toolkit. Its first-aid and identification content is a stopgap for information-scarce situations — not a substitute for professional care or expert identification.
What platforms are supported?
Android, via Google Play. The app is free to download and includes a 3-day full trial before the one-time unlock.
Do you make other offline apps?
Yes — Power Prepper is one of a family of offline, on-device-AI reference apps built on the same engine: Fixwright for repair and trades, Warden for phone privacy, with Roots (homesteading) and Yarrow (herbal reference) on the way. See the full lineup.
