Beta for iPhone and Android
Add a PDF or a photo of your lab report. Zyva shows each value next to your lab’s range, explains it in plain words and lines up your reports, so you see how each value changes.
Free in the beta. Information only, not medical advice.
The problem
A page of numbers, different units, a few values marked H or L. An online search tends to show the worst case first. Zyva shows what is in range, what is worth a look and what changed since your last test.

Reports from different labs and years line up in one timeline per value.
Scan the barcode or the label and get a score from 0 to 10 for quality and value. Brands can’t pay for it.

How Zyva checks its knowledge
Zyva builds its knowledge about lab values and supplements before you ask anything.
Several AI models describe the same fact. Only what they agree on goes forward.
Zyva checks each statement against medical databases and studies. Without a source, it is dropped.
What passes is stored as medical knowledge, separate from your personal data.
Health Vault
Zyva creates your vault key on your phone. It locks the app and protects the names of your family members. A 12-word phrase or an encrypted cloud backup brings it back. It does not encrypt your lab values.
Your account and records are stored in the EU.
No ads. We don’t sell your data, and we don’t sell supplements.

Our own open-source text recognition model reads the whole file. It runs on rented servers in the EU or the USA, depending on capacity. Before AI providers in the USA and China receive your values, units and ranges to sort and explain them, we remove your name, date of birth and address. Questions you type in Ask Zyva go to an AI provider in the USA as you write them, after we automatically remove email addresses, phone numbers, IBANs, dates and ID numbers. Names you type can remain, so please leave them out. Details are in the privacy policy.
Your account and records are stored in the EU. Reading and explaining reports can involve servers and AI providers outside the EU, as described above. We don’t sell your data, and there are no ads.
