Stack Precision: Supplement AI

Most apps remember what you took. Stack Precision tells you what it's doing, for your supplements and your peptides.

More than a supplement tracker: it holds everything you take, your journal, your genetics, and your Health Connect data on one timeline, then reads across all of it over weeks and months to find the patterns that only show up when the pieces come together.

WHY IT'S DIFFERENT
Supplement trackers and peptide trackers log and remind. Stack Precision is an instrument: it analyzes. It looks at your supplements, journal, genetics, and measurements together, finds where they move with each other, and tells you how strong each signal is, so you know what's worth acting on.

WHAT IT READS
• Everything you take: supplements, vitamins, meals, and peptides, with dose, timing, and reminders
• Your journal: how you actually feel, logged against what you took
• Your genetics (optional): your DNA file, read as evidence and cited against published research
• Your measurements: Health Connect, on the same timeline

NO DNA FILE? START ANYWAY
The analysis runs on your supplements, peptides, journal, and Health Connect data from day one. Add your DNA whenever you're ready and every insight gets another layer of evidence.

CAPTURE WITHOUT THE FRICTION
• Scan a supplement label and the ingredients, servings, and doses load themselves
• Photograph your meal and AI logs what you ate, down to the micronutrients, mapped against your results and journal entries
• Speak your journal entry and it lands in the record, feeding the analysis

THREE WAYS IT WORKS
• A weekly read surfaces a pattern worth your attention, on its own
• A chat that knows your whole record: ask anything, and the answer is grounded in your actual stacks, entries, and markers
• A research run takes a harder question, plans its own steps, ranges across your whole record and the published literature, and returns one report with its reasoning and sources laid out

BUILT TO BE CHECKED
Every read names the data behind it and shows its work. When an insight involves your genetics, it cites the specific published studies it drew from, pulled from a curated research library, so you can read the source yourself. It tells you when something is a direction worth investigating. It never diagnoses, treats, or prescribes. Discuss changes with your clinician.

PRIVATE BY DESIGN
Built on HIPAA-compliant infrastructure. Your health and genetic data is never sold and never used for ads. You choose what the analysis can see, and your DNA stays yours.
