Overview

<p><b>Startup description</b></p><p>My product is a keto companion app for iOS and watchOS: macro tracking, AI meal suggestions, fasting timer, electrolyte tracking, and HealthKit sync. I built it as part of a 30+ app portfolio to prove out on-device AI in the health niche — the AI runs entirely on Apple's Foundation Models, so it has zero API costs. It's live on the App Store with active paid subscribers. I'm selling to consolidate focus on my core product line.</p><p><b>Key highlights:<b></b></b></p><ul> <li>Revenue: early stage — $27 total proceeds, $5 MRR, 2 active paid subscriptions</li> <li>Trial-to-paid conversion: 9% (D1), 10% (D7), 20% (D35)</li> <li>Operating cost: $0/month beyond Apple developer account (on-device AI + CloudKit, no backend)</li> <li>Margin: effectively 100% after Apple's commission (15% small business program)</li> <li>Churn/LTV/CAC: not statistically meaningful yet at this volume — no paid acquisition has been run (CAC is untested, all traffic organic)</li> </ul> <p><b>Team</b></p><p>Solo founder/developer (senior iOS engineer). Design, development, ASO, and App Store operations all handled by one person. No employees, no contractors, no ongoing obligations transfer with the sale.</p><p><b>Tech Stack</b></p><ul> <li>Swift / SwiftUI — entire app, modern codebase, minimal third-party dependencies</li> <li>Apple Foundation Models (on-device) — AI meal suggestions; no API keys, no per-request costs</li> <li>HealthKit — health data sync</li> <li>CloudKit — sync/storage; no backend servers to maintain</li> <li>watchOS companion app — full watch experience included</li> <li>StoreKit 2 — subscription infrastructure, configured and live</li> </ul> <p><b>Marketing and growth</b></p><p>Zero marketing has been done. All downloads are organic App Store search traffic. That's the honest state and also the opportunity: a 20% D35 trial-to-paid conversion with zero optimization means the product converts — it has never been given traffic. No ASO iteration, no paid UA, no content, no social presence for this app. A buyer with a health-niche audience or UA skills starts from a proven conversion funnel, not a cold product.</p><p><b>Revenue and profit</b></p><ul> <li>MRR: $5 (2 active subscriptions at legacy pricing; new subscription price being raised to $3.99/mo)</li> <li>Total proceeds to date: $27</li> <li>Profit ≈ revenue (no operating costs)</li> <li>Retention cohorts: D1 9% / D7 10% / D35 20% download-to-paid</li> <li>No refunds issued to date</li> </ul> <p><b>Return on investment</b></p><p>At $4,500 ask: buyer needs ~95 subscribers at $3.99/mo to reach $375 MRR ≈ 12-month payback. Given a 20% D35 conversion, that's roughly 500 downloads — achievable via basic ASO work or one small influencer collaboration in the keto niche. Keto/macro tracking is an evergreen, high-search-volume category; comparable apps monetize at $5-15/mo price points, so pricing headroom exists above my conservative $3.99.</p><p><b>Startup assets<b></b></b></p><ul> <li>Full Swift/SwiftUI source code (iOS + watchOS), git history included</li> <li>App Store listing + App Store Connect transfer (app is transfer-eligible, no shared CloudKit container)</li> <li>2 active paid subscriptions transfer with the app</li> <li>ASO assets: keyword research, screenshots, description source files</li> <li>Subscription infrastructure fully configured (StoreKit 2)</li> <li>2 weeks of post-transfer technical support from me</li> <li>No email list, no social accounts — nothing hidden, what's listed is what exists</li> </ul> <p><b>Risks</b></p><ul> <li>Early-stage revenue: conversion cohorts are strong but based on small absolute volume. Mitigation: the ask is priced on replacement cost (~300 hours senior iOS development), not revenue multiples — you're buying a finished product, not cash flow.</li> <li>Traffic dependency: currently 100% organic App Store search. Mitigation: this is unoptimized — ASO and any paid/influencer channel is untapped upside, not a repair job.</li> <li>Platform risk: iOS-only, subject to Apple policy. Mitigation: app is fully compliant, approved, and uses only first-party Apple frameworks — no gray-area SDKs.</li> <li>Keto niche competition: crowded category. Mitigation: on-device AI + watchOS + zero running costs is a differentiated cost structure competitors with OpenAI bills can't match on price.</li> </ul> <p><b>Summary</b></p><p>You're buying a finished, App Store-approved, AI-featured health app with a proven 20% D35 conversion rate and zero monthly operating costs — for roughly the cost of 3 weeks of senior iOS contractor time. The development risk is eliminated (it's built, approved, live, converting). The only work remaining is the work most buyers actually want to do: distribution. If you have an audience, ASO skills, or UA budget in the health/fitness space, this is a conversion-proven funnel waiting for traffic, with 100% margins on every subscriber you add.</p><p>✅ $27 TTM revenue</p><p>✅ 2 customers</p><p>✅ Business model: SaaS</p><p>✅ Built with Swift, SwiftUI</p>

Business Model

Freemium with auto-renewable subscription. Free tier: core macro tracking. Premium unlocks AI meal suggestions, fasting support, and advanced tracking at $3.99/mo (recently repriced from launch pricing; existing subscribers grandfathered).

Target Audience

People actively following a ketogenic diet who track macros daily — primarily 25-45, health-conscious, iPhone + Apple Watch owners. Sub-segments: keto beginners needing meal guidance (AI suggestions), intermittent-fasting practitioners (fasting timer).

Asking Price Reasoning

Priced on replacement cost, not revenue multiple. Rebuilding this app — iOS + full watchOS companion, on-device AI integration (Apple Foundation Models), HealthKit sync, StoreKit 2 subscription infrastructure, App Store approval.

Reason for Selling

Consolidating focus. I've shipped 30+ apps and I'm narrowing to my core product line (Mac creative suite and developer tools). This app is a finished, converting product outside that focus — it deserves an owner who will drive distribution.

Growth Opportunity

The product converts; it has never been given traffic. Untapped levers, in effort order: ASO iteration — keyword optimization has never been done; keto/macro terms have high evergreen search volume Pricing headroom — comparable keto apps charge $5-15/mo.
