Most apps remember what you took. Stack Precision tells you what it's doing. It holds everything you take, your journal, your genetics, and your Apple Health 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 and peptide apps 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 and meals, with dose and timing • 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: Apple Health, on the same timeline NO DNA FILE? START ANYWAY The analysis runs on your supplements, peptides, journal, and Apple Health 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. 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. PRICING • Always free: track your supplements, peptides, and journal, with a fresh AI insight every week • Base ($1.99/month): folds Apple Health and your genetics into the analysis and unlocks research runs • Plus ($4.99/month): more AI use every month and additional deep dive research runs Know what your stack is doing.

This is def easy. Also uploaded my genetics and the AI chat helped me think of questions to ask my doctor during my next visit. V cool. ### 5/5 — Very cool tool *2026-03-17* This app is really informative. It’s very easy to add whatever supplements you’re taking to your profile. All you do is scan the barcode and all the info comes up including dosage, what kind of tablet and main ingredients. I also really like the daily journal entry option.
