The biology layer
Put the DNA test you already paid for to work
Genetics in Stack Precision is one more layer of evidence in the analysis. Upload the 23andMe, Ancestry, or VCF file you already paid for and it starts working the day you drop it in, read into trait-level insights and folded into what the app watches for you.
Always free.
Your genetic profile, read into trait-level cards. Each one ties a gene variant to what nutrigenomic research associates with it.
On upload
Upload the file you already have
Drop in your 23andMe, Ancestry, or VCF file and it is parsed entirely on your device. Stack Precision reads 194 relevant variants, tied to methylation, vitamin D, detox, antioxidants, and more, and keeps only the ones you choose to save. Your raw genome never leaves your phone.
The analysis runs in full on your supplements, peptides, journal, and Apple Health. A DNA file adds one more layer of evidence when you want it: once your variants are in, they sit beside the doses and journal you log on your timeline, so the app reads them together.
Read against your stack
Your variants become context for every read
What the app watches in your data is shaped by your genetics. A variant in your file can seed something it holds for weeks, then closes with a plain verdict. You get reads pointed at your biology instead of a textbook average.

Your cohorts
Compare notes with your cohorts
See how people who share a variant with you tend to build their stack, grouped by the traits you have in common and never by a name. It is a way to read your own choices against the people your biology most resembles.
Your genome stays yours
Parsed on your phone, kept on your phone
Your raw file is read on your device and only the variants you keep are saved. The full account of how your data is held is on the trust page.
Drop in your file and see what it ties to
Upload once and let your variants start shaping what the app watches.
Always free. On iOS and Android.
