<p>I built this app for iPhone and Apple Watch to help people understand physiological stress and recovery patterns from heart rate, HRV, sleep and activity. It uses HealthKit data and on-device processing, with no account or dedicated backend. It is a general wellness app, not a medical device.</p><p>The app launched on 2 April 2026 and uses an App Store monthly subscription. </p><p><b>Apple Sales &amp; Trends </b></p><p>Reported $47.60 in sales and $27.11 in estimated developer proceeds for 8 November 2025–7 November 2026. These are historical dashboard figures, not MRR or finalized payments. Recent app units were 2 for 9 October–7 November 2026, not active users.</p><p><b>Costs</b></p><p>There are no direct recurring paid API or hosting costs. Apple deductions are reflected in the proceeds; shared developer membership, studio website/domain costs, owner labor and personal taxes are excluded. Revenue and traffic are small; growth and buyer payback are not guaranteed.</p><p><b>Asking Price Reasoning</b></p><p>The $1,500 asking price is for the completed product and owned source assets, not an income valuation. Proposed assets include source/project files, app-specific branding and documentation, and App Store record transfer subject to Apple eligibility and dependency review. The domain and unrelated apps are excluded. Third-party dependencies keep their licenses. HealthKit records remain on users’ devices; no health-data database is offered. Transition assistance would be agreed separately.</p><p>Possible growth work includes App Store presentation, onboarding and localization, subject to testing. Wearable data can be intermittent, and Apple platform and subscription policies are ongoing dependencies.&nbsp;</p><p>✅ $48 TTM revenue</p><p>✅ 1 customer</p><p>✅ Business model: SaaS</p><p>✅ Built with&nbsp;Swift</p>
