Stack Precision: Supplement AI
Find the patterns in your data
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Now live: our biggest update yet. Your supplements, journal, genetics, and Apple Health, read together so you finally know what your stack is doing.
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 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 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 to act on.
WHAT IT READS
• Everything you take: supplements, meals, and peptides, with dose and timing
• Your journal: how you actually feel, logged against what you took
• Your genetics: your DNA file, read as evidence inside the analysis and backed by published research
• Your measurements: Apple Health, on the same timeline
TWO WAYS IT WORKS
• A weekly read surfaces a pattern worth your attention, on its own
• A research run takes a harder question, plans its own steps, ranges across your whole record and the 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. It tells you when something is a direction worth investigating, not a verdict. It never diagnoses, treats, or prescribes.
PRIVATE BY DESIGN
HIPAA compliant. Never sold. Pseudonymous by default. You choose what the analysis can see.
PRICING
Free: reads your supplements and journal, surfaces an insight a week, 20 credits a month. No credit card.
Subscriber ($1.99/month): folds Apple Health and your genetics into the analysis and opens research runs on demand, 200 credits a month.
