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. YOUR PREVENTION PLAN, PERSONALIZED • Answer a few questions and see the screenings and preventive actions that published guidelines recommend for someone like you • Plain-language "why this is in your plan" reasons for every item • Due dates, completion tracking, and optional reminders FOUNDATIONS FIRST HABITS • Build the four foundations - sleep, nutrition, exercise, stress - with streaks, heatmaps, and a 30-day timeline • Deeper educational content unlocks as your habits grow.
