Health, home and travel decision
Health3
A competent developer can reproduce a useful subset (OCR parsing, biomarker mapping, reports, HealthKit import) in a multi-week build, but matching the polished app, curated biomarker content, App Store polish, and ongoing product maintenance makes a full replacement impractical for a single person to sustain long-term.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User uploads a lab-result image or imports clinical records, app OCR/parses values, normalizes biomarkers, stores results, and renders a shareable Test Report with trends and insights.
What it still won’t have
- Polished mobile UX and onboarding refinements
- Curated and maintained biomarker library, literature-sourced reference ranges and explanations
- Ongoing App Store distribution, updates and mobile-specific bug fixes
- Subscription, trial management and in-app purchase flows already implemented
- Security, privacy reviews, and continuous clinical data handling improvements
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Health3 does not publish a price we could read, so there is nothing to compare against. What building costs is below.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal Health3-style iOS app and backend using: iOS SwiftUI app + HealthKit for Apple Health import, a small Node.js (Express) API with Postgres for storage, Tesseract (or cloud OCR fallback) for image parsing, and Puppeteer/HTML-to-PDF for report export. In scope: image upload UI, OCR pipeline that extracts labeled biomarker name/value/date, a biomarker canonicalization table with unit conversions, basic trend charts, shareable PDF Test Report, Apple Health import button that maps supported clinical-record biomarkers, user auth (email+password), and one reminder scheduler. Out of scope: subscription/in-app purchase billing, advanced machine-learning document parsers, large-scale analytics, and mobile push notifications. Include error handling for failed parses, unit-mismatch detection, and tests for OCR parsing, biomarker mapping, HealthKit import, and PDF generation.
How we checked
How the score was reached
- Partly verdict base52
- 3 cited sources+3
- 3/3 assessment runs agreed+4
- Evidence score59
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
