Most people guess with supplements. You don't have to.

Your genetic data already holds clues about which supplements may work for your body. Stack Precision makes those clues actionable in three steps.

1

Upload Your Genetics

Upload your raw data file from 23andMe, AncestryDNA, or whole genome sequencing. We scan for 194 specific variants across 19 health categories and build your Genetic Profile.

Parsed on your device

Your raw genetic file is processed on your phone. It is never uploaded to or stored on our servers.

Transparent evidence tiers

Every variant includes why we track it, what the research says, and what it may mean for your supplement considerations.

19 health categories

From methylation and detoxification to cardiovascular health and neurotransmitter balance. See the full picture.

Track Your Stack

Adding supplements should take seconds, not minutes. Point your camera at any label and AI reads it for you -- name, brand, form, serving size, and ingredients, filled in automatically.

AI label scanner

Scan any supplement bottle with your camera. AI vision reads the label and auto-populates the entry form. No typing required.

Flexible scheduling

Organize supplements by morning, afternoon, night, or take-anytime. Set reminders. Track completion daily.

Daily wellness journal

Score six dimensions daily: energy, mood, focus, calm, sleep, and comfort. Build the dataset your AI needs to look for patterns.

Free forever

Core supplement tracking and journaling costs nothing. No paywall on the features that matter most.

Ask AI What's Working

Your private AI assistant looks for potential patterns between your genetics, supplements, and wellness journals. Ask anything about your data and explore evidence-informed insights tailored to your profile.

You control what AI sees

Choose exactly which data the AI can access: stacks, journal entries, genetics. Your name is never sent.

Monthly consent renewal

AI consent expires every 30 days. You re-authorize on your terms, not ours. No auto-renewal buried in settings.

AI credits at cost

We pass through AI costs without markup. You pay for what you use, and core features remain free.

What makes this different

Not another pill reminder.

Other apps track what you take. Stack Precision helps you explore why it may matter, based on your genetics.

Genetics-first

Your supplement insights are based on your actual genetic variants, not a generic questionnaire or marketing quiz.

Community intelligence

See anonymized trends from people who share your genetic variants. What are they taking? At what doses? Is it helping?

Privacy as architecture

HIPAA-compliant from day one. On-device genetic parsing. No data sales. Your health data is treated like medical records.
