An AI answer about your health is only as trustworthy as what it is based on. Some apps name the source behind each fact so you can check it; most say their answers come from "trusted sources" or "internal frameworks" without showing which.
We compared AI health apps on whether their health facts name a source, and whether they answer from your own data first.
We make Emerge Care, so it is listed first. Every other app is ranked on the criteria below, and each fact links to a comparison page with its sources.
Every health fact cites MedlinePlus, Mayo Clinic, the CDC or the NIH, and it tells you when it has no trustworthy source instead of guessing. Tap Sources under any answer to see them.
