Aron is an offline survival library. All books, answers and smart search live right on your phone: the app works with no internet and no signal — in the woods, on the road, during outages.
Aron is an independent private app. We do not represent any government entity, are not affiliated with any government entity, do not act on their behalf and do not provide government services. The library contains official documents that are publicly available; links to the original sources are at the end of this description and on the "Sources" screen inside the app.
WHAT'S INSIDE
• "I'm in trouble" — big emergency tiles: fire, flood, storm, crash, evacuation. Each leads to short step-by-step answers. Calling the emergency service takes one tap — the number is picked for your country (112, 911, 999 and others).
• Knowledge shelves — hundreds of ready answer cards by topic: water, food, fire, heat and cold, natural hazards, transport, security, preparedness.
• Real books — publicly available official documents: the U.S. Army Survival Manual FM 21-76 (MCRP 3-02F reprint), FEMA and Ready.gov guides and hazard info sheets, CDC materials, a U.S. Fire Administration brochure, and civil-protection leaflets from EMERCOM of Russia and Rospotrebnadzor. When an answer comes from a book included in the app, it opens right on the exact page.
• Smart search — ask in your own words: "how to purify water", "leg cramp while swimming". Aron searches by meaning, not by letters, and understands typos.
• "My books" — add your own books (EPUB, FB2, TXT, DOCX) and Aron will search them too. Everything stays on your phone only.
• Tools — a whistle, an SOS light and a compass on the bottom bar.
HOW TO USE — THREE STEPS
1. In trouble? Tap the red "I'm in trouble" button, pick the tile that matches and follow the short steps.
2. Have a question? Type it in your own words in the search bar and tap the magnifier. Open a card — and tap "Answer from the book" to see the original source page.
3. Preparing ahead? Browse the shelves by topic and add your own books to "My books": when the hard hour comes, everything will be at hand, even with no signal.
Everything you need is already inside the app: no internet is required, not even on the very first launch.
HONESTY AND SOURCES
• The library contains only official, freely distributable documents (public domain and official government materials); every book lists its source.
• Some Russian-language files are our own unofficial translations of U.S. government documents; this is stated both in the file and on the card.
• Some answers are our summaries of official recommendations and survival books; every card says where the facts come from.
• No ads, no subscriptions, no data collection. Pay once — use forever.

IMPORTANT
Aron is a reference library — not a government service and not an emergency service. It does not replace doctors or emergency services: if life is in danger, call 112 (or your local emergency number). Perform medical procedures only when professional help is unavailable.
