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. Your highest-ROI health actions, in the right order
• Optional Apple Health connection pre-fills your daily logs (read-only; your data stays on your phone)
EVIDENCE YOU CAN CHECK
• Every item shows its evidence grade and tier (1-5), from USPSTF A/B guidelines to clearly-labeled emerging research
• Trending Claims feed separates myth from fact, with citations
• Evidence is never paywalled. Every guideline, grade, and deep dive is free
PRIVATE BY DESIGN
• No account. No server. No ads. No tracking.
• Everything you enter stays on your device. The app makes no network connections
• Delete all your data anytime with one tap
OPTIONAL ONE-TIME PURCHASE
• Premium Lifetime Unlock ($4.99, one-time - not a subscription) adds PDF Prevention Reports: export a clinician-ready summary of your plan to bring to your next visit

Fixes and polish.
- You can now mark a recommendation complete from anywhere you open it, including from Learn and from Habits > Discover.
- VoiceOver users can check in on any habit card directly, and cards now announce whether you have checked in today.
- The first time you log a habit, you will no longer get two prompts at once.
