Here's what the evidence shows, personalized to you.

Foundations first

Your highest-ROI health actions, in the right order

Sleep, nutrition, movement, and stress are where the science is most confident — so Headwater starts there. Master the foundations and more advanced, evidence-tiered wellness content opens up as you go.

Streaks, gentle pacing, and no punishment for missed days. Back at it — not "streak lost."

Evidence, graded

Every recommendation cites its source

The grading system is the product. Each screening and habit carries its USPSTF grade or evidence tier, a plain-language "why this matters," and the source references behind it — the way a physician friend would explain it over coffee, not across a desk.

Cutting through the noise

What the research actually shows

A myth-busting feed takes trending wellness claims — cold plunges, supplement stacks, peptide protocols — and grades them against the published evidence, with citations you can check yourself.

Curious, not alarmist. Honest about uncertainty.

Build the habit

Momentum you can see

Streak cards, a calendar heatmap, and a 30-day timeline keep the four foundations visible at a glance. Optional Apple Health integration pre-fills your daily logs — read-only, and always your choice.

Honest about frontier science

Emerging topics, clearly labeled

From peptides to nootropics, Headwater covers the topics people are actually curious about — and labels exactly where each one sits on the evidence ladder, from FDA-approved to not approved for human use.

This is where the science is most confident — and where it isn't yet.
