Where Function is stronger
Function removes testing logistics for eligible US members. Its official materials describe 100+ tests in an annual test, 60+ at mid-year, 160+ total annually, and scheduling through more than 2,000 Quest locations. Function also describes clinician review, issue flags, and calls for critical results.
Where Health3 is stronger
Health3 is an informational and wellness tracking workspace available on the web, iOS, and Android. Its current mobile catalog contains 182 biomarkers, and the interface is multilingual. Users can add lab results from PDFs, report photos, manual entry, and Apple Health Clinical Records on iOS; review extracted values before saving; follow measurements and reference context over time; and export reports. Health3 does not order tests, employ clinicians, diagnose conditions, or recommend treatment. The US App Store listed a free tier plus Premium at $9.99 weekly, $14.99 monthly, $99.99 yearly, or $149 lifetime on August 19, 2026; prices differ by country and platform.
Health3 is provider-independent and useful when reports come from several clinics, national systems, employer checks, or private laboratories. The user reviews extracted data before saving. Health3 is not a substitute for Function’s testing or clinician-review process.

Can you use both?

Medical boundary
Function describes testing, clinician notes, and health protocols. Health3 does not diagnose, prescribe, order tests, or recommend treatment. Any clinical concern should stay with Function’s licensed process or another qualified professional.
