Kozen-X is four layers stacked into one loop. Read the data your body is already broadcasting. Translate it into the single right thing to take. Surface a vetted SKU. Close the cart in one tap. Then learn from what you actually did, and get sharper every week.

L1.
Layer · Data ingest

Read what's already there.

Apple Health on day one. Whoop, Garmin, Oura, Fitbit on the roadmap. Manual logging for everything that doesn't have a wearable yet. One source of truth for your training load — sleep, HRV, sweat, intensity, recovery debt.

L2.
Layer · Recommendation engine

Decide, don't describe.

Most apps tell you what you did. Kozen-X tells you what to do next. The engine reads context — workout intensity, sleep debt, hydration, HRV trend — and surfaces the single right thing to take, when, and how much. Evidence-graded, target latency under 90 seconds from signal to suggestion.

L3.
Layer · The honest shelf

~40 SKUs, vetted three ways.

Curated roster from brands that pass formulation, third-party testing, and price-fairness checks. If a brand games one, it doesn't make the shelf. Affiliate disclosure is always visible. Founder-tier pricing locks for the first 500 on the waitlist — for life.

L4.
Layer · The loop

One tap, one cart.

Routing engine sends every order to the cheapest honest source. Reorder cadence auto-tunes to your training load — no "running low" notifications, the box just lands. Kozen Points earned per purchase, redeemable shelf-wide. Connect → learn → buy → repeat.
