<p><b>Startup description</b></p><p>My app is an offline survival AI assistant for iOS. It runs a custom on-device model — downloaded once, then fully offline forever — that gives calm, actionable guidance for first aid, water sourcing, shelter, fire, and emergencies, with no signal, no account, and no data leaving the device. I built it as part of a 30+ app portfolio; it's consistently the #1 app in that portfolio by downloads.</p><p><b>Key highlights:<b></b></b></p><ul> <li>~120 first-time downloads/month, 5.6K monthly impressions, 554 monthly page views — all organic, zero marketing</li> <li>3.16% product-page conversion, steady daily download cadence</li> <li>#1 app by units across a 30-app portfolio</li> <li>Monetizes via a $12.99 one-time unlock (no subscription) — proven the niche pays upfront</li> <li>Business margin ~100% — offline model, zero API/server costs</li> <li>Operating cost: $99/yr developer account, nothing else</li> </ul> <p><b>Team</b></p><p>Solo founder/developer (senior iOS engineer, 30+ shipped apps). All work by one person. No employees or contractors; no obligations transfer with the sale.</p><p><b>Tech Stack</b></p><p>Swift, SwiftUI, C++ (llama.cpp integration bridging the local LLaMA model to Swift for on-device inference), custom on-device survival model (LLaMA-based, two size variants for older/newer iPhones), one-time model download, zero network calls after installation. No backend, no third-party APIs, no cloud inference. StoreKit for the $12.99 unlock.</p><p><b>Marketing and growth</b></p><p>No marketing has been done — 120 downloads and 5.6K impressions per month are entirely organic App Store discovery. Two clear upside levers: (1) the survival/prepper niche has never been targeted — its exact selling point ("works with zero connectivity") is tailor-made for prepper communities, offline-tool roundups, and outdoor channels; (2) paywall conversion is low (D1 0.8%, D7 0.9%) and completely unoptimized — unlock timing, price testing, and onboarding are all untouched. Strong top-of-funnel, underdeveloped monetization.</p><p><b>Revenue and profit</b></p><p>$12.99 one-time unlock; profit ≈ revenue (only cost is the $99/yr dev account). Consistent organic download volume; monetization is currently underoptimized (&lt;1% download-to-paid), which is the buyer's upside rather than a structural problem. No subscription, so no churn.</p><p><b>Return on investment</b></p><p>At $4,500, two payback paths. (1) Distribution: the product and its zero-cost model are done; a buyer with reach into survival/prepper/outdoor communities converts a passionate audience at $12.99 with no per-user cost. (2) Conversion: 120 monthly downloads at &lt;1% paid is a funnel a buyer can optimize — even lifting to 3-5% meaningfully changes monthly revenue with zero new traffic. Alternatively, the offline-model integration represents ~300 hours of senior iOS work — build cost avoided on day one.</p><p><b>Startup assets<b></b></b><b> </b></p><ul> <li>Full Swift/SwiftUI source, including the on-device model integration and inference setup, git history</li> <li>The custom survival model file + curated knowledge base as shipped</li> <li>App Store Connect transfer — approved, live, transfer-eligible</li> <li>StoreKit $12.99 one-time unlock configured</li> <li>ASO assets: keywords, screenshots, description sources</li> <li>30 days post-transfer technical support</li> <li>No email list, no social accounts, no user database — nothing hidden</li> </ul> <p><b>Risks</b></p><ul> <li>Low paywall conversion (&lt;1%) — this is untouched upside (pricing/onboarding never tested), not a broken funnel; strong organic download volume is already there.</li> <li>Traffic concentration — mitigated by a clearly-defined, never-targeted niche (survival/prepper) whose core need matches the product exactly.</li> <li>Platform risk (Apple-only) — mitigated by first-party frameworks, full compliance, and an offline model with no external service to break or deprecate.</li> <li>Model maintenance — the on-device model is self-contained; no API to deprecate, no server to run.</li> </ul> <p><b>Summary</b></p><p>My app is a finished, App Store-approved, fully offline survival assistant — the #1 app by downloads in a 30-app portfolio — pulling ~120 organic downloads and 5.6K impressions a month with zero marketing. It monetizes with a proven $12.99 one-time unlock and costs nothing to run. The opportunity is two-sided: a passionate niche that has never been marketed to, and a paywall converting under 1% that a competent buyer can lift substantially. You're buying strong organic demand and a distinctive offline-LLM product for roughly the cost of building it — with both distribution and conversion still wide open.</p><p>✅ $9 TTM revenue</p><p>✅ 150 customers</p><p>✅ Business model: LTD</p><p>✅Built with Swift, SwiftUI, C++</p>
