Every recommendation cites its source. See what published guidelines say about someone like you, then build the habits that matter most. Your data stays on your phone. Cut through the wellness noise. Headwater shows you what published preventive-health guidelines including USPSTF, CDC, and NIH actually say about people with your profile. Every recommendation is graded by evidence, explains why it applies to you, and links to its source. Created by a board-certified family medicine physician.

- Fixed Apple Health syncing: after you allow Headwater to read your data, it now syncs instead of stopping at the permission step. - When only some of your Apple Health data, or none of it, is visible to Headwater, the app now says so plainly instead of reporting that access was denied.
