Stack Precision
Supplement Stacks, Decoded
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
You take supplements every day. Do you know which ones are actually making a difference?
Stack Precision allows you to track what you take, journal how you feel, and use AI to find the patterns you can't see manually. Add your genetic data for a deeper layer of insight into why your body responds the way it does.
We built Stack Precision because your health decisions should be informed by your own biology, not by marketing claims on a bottle. The supplement industry is full of one-size-fits-all advice. Your body isn't one-size-fits-all. Your context matters.
This app doesn't tell you what to take. It gives you the context to make your own informed choices and a place to track what's working.
TRACK YOUR STACKS
Point your camera at any supplement label and AI reads it for you. Name, brand, serving size, ingredients — added in seconds, not minutes. Build stacks with dosages, schedules, and reminders. Log what you take and when. Over time, your supplement log becomes a detailed personal record you can reference and share with your healthcare provider.
JOURNAL HOW YOU FEEL
Rate your energy, mood, focus, calm, sleep, and comfort each day. Over days and weeks, trends emerge between what you take and how you feel. Your entries stay private and searchable, building a personal health timeline only you can see.
ASK QUESTIONS WITH AI
Your private AI assistant looks for patterns between your supplements, timing, and health journals. Ask anything about your data and explore evidence-informed insights tailored to your profile. Responses cite research and evidence tiers, not just opinions. It's a research tool for your own data, not a substitute for professional guidance.
YOUR GENETIC PROFILE, IN CONTEXT
Import your genetic data from 23andMe, AncestryDNA, or whole genome sequencing. Stack Precision maps 194 variants across 19 health categories — methylation, detoxification, vitamin metabolism, and more — and shows you what published research has found about each one. No diagnoses. No prescriptions. Just your data, organized and accessible.
COMMUNITY TRENDS
See anonymized supplement patterns from people who share your genetic variants. What they take, at what doses, and how it compares to your stack. Fully opt-in. Fully anonymized. Always your choice.
PRIVACY AS A FEATURE, NOT A FOOTNOTE
Stack Precision is HIPAA-compliant. Your data is encrypted, access-controlled, and never sold. There are no ads. You can create an account without an email address — fully pseudonymous. Your genetic file is parsed on your device and never stored on our servers. Your health data belongs to you, and we've built every layer of this app to keep it that way.
