Store description excerpt
Picture this: the grid fails, the signal dies, civilization teeters. Your phone still has battery—but the cloud is gone for good. What you need isn't another online tool. It's **a classroom you can download**: once the download finishes, humankind's survival wisdom lives on your device for good. This is ArkSurvival. 【Why it "won't die"】 ■ Fully offline Every guide is built into the app, and the AI model runs entirely on-device. No servers, no account, no subscription. Once installed, it lives and dies with your phone. ■ Privacy by design Your questions, notes, and supply lists never leave this device—not a single byte. When civilization is fragile, privacy isn't a feature; it's the baseline. ■ Works with no connection Airplane mode, deep wilderness, an underground bunker, a signal dead zone—the harsher the environment, the more reliable ArkSurvival gets. Being offline is exactly its home turf. 【A survival library in your pocket】 12 domains, 96 curated how-to guides: water purification, fire, food preservation, first aid, shelter, farming, materials and smelting, energy and electricity, communication, sanitation, safety and defense, and society—from "survive day one" to "rebuild the electric age." It's a bookshelf of survival lore you can search in a single second. 【More than an encyclopedia—a mentor in your pocket】 ◆ Ask Ark: on-device AI answers grounded in the knowledge base, and every answer cites its source entries—verifiable, never hand-wavy ◆ Guided follow-ups: after each answer you get suggested next questions—because in a crisis, knowing what to ask matters as much as the answer ◆ Rebuild Civilization tech tree: Survival → Settlement → Farming → Early Industry → Electricity → Information. 6 stages, 34 nodes. Mark what you've mastered and practiced, and watch civilization restart in your hands ◆ Offline notes and supply lists: record plans, track inventory—when the world ends, your stock is your decision-making ◆ Fully offline, bilingual: switch the interface and the entire knowledge base between English and 中文 in one tap 【Under the hood—in plain terms】 ◆ On-device LLM: a full AI model (Qwen 0.8B, CoreML-compiled, int8-quantized) runs entirely on your phone. Plain terms: an offline AI in your pocket—ask and it answers on the spot, no server involved. ◆ Retrieval-Augmented Generation (RAG): before answering, it retrieves the most relevant source text from the knowledge base, feeds it to the model as evidence, and cites the source. Plain terms: it doesn't make things up—every claim is traceable to a source you can open and check. ◆ Offline inverted-index search: all 96 guides are indexed like a search engine (field-weighted scoring + CJK bigram tokenization) for millisecond-fast hits. Plain terms: a tiny search engine built in—type two words, get the answer instantly. ◆ Exact 2048-token context budgeting + GPU acceleration: a real tokenizer counts length precisely; inference prefers the GPU and falls back automatically.
