Know exactly what you're taking.
And what it clashes with.
Your shelf is a guessing game. Kozen-X holds every supplement and medicine you take — expiry | timing | what clashes with what — and checks the whole shelf against a knowledge base of 560 entries, every line quoted from a published source. Connect Apple Health and your steps, resting heart rate, HRV and sleep sit alongside it.
The first 300 accounts never pay the subscription. Join the list and you're in the queue for a founder number — 1 to 300, claimed when the app opens. One confirmation email + launch news, nothing else · Terms apply · Privacy
Add a medicine, and it re-checks the whole shelf against it.
Every supplement you own, actually understood.
Add what you take — by name or by scanning the label — and Kozen-X tracks the rest: how much is left, when it runs out, when to take it, and what it clashes with. Branded products resolve to the ingredients actually inside them, so a creatine blend is checked on its calcium and magnesium too.
Your watch tracks everything. Your shelf knows none of it.
Connect Apple Health and your day sits next to your shelf — steps, active energy, resting heart rate, HRV, sleep and cardio fitness, each with a plain-English note on what it actually means. Every dose you log is written back to Apple Health.
No brand pays to be on your shelf.
Nobody buys their way into the knowledge base, and nobody buys their way onto your shelf. Buy wherever you like — it still gets logged. What we charge for, eventually, is the app itself: the first 300 accounts never pay the subscription.
560 entries. Every one sourced.
Founder 1 to 300.
The first 300 accounts get a founder number and never pay the subscription. When the app is paywalled later, founders keep the app and its features free for life. Number 301 onwards pays; a month costs less than your Starbucks coffee. Covers the app subscription only — not physical products, should we ever sell any. Subject to our Terms. Launching soon.
