Everything in one place

From your lab's PDF report to a plan you can act on.

Import a PDF, snap a photo, or type your results once. Verith organizes every marker, tracks it over time, and tells you what to do next.

Import your lab report

Bring in the official PDF from your lab for the most accurate import — or snap a photo of a paper copy. Everything is read on your device, and the original report is archived to your iCloud Drive, kept safe beyond the import.

Every marker, organized

Metabolic, cardiovascular, inflammation and more — searchable and grouped, each with its optimal range.

Biological age

Track your PhenoAge and KDM biological age against your chronological age — the science-backed way to see how you're really aging.

Trends over time

Every result becomes a timeline. Spot what's improving, what's drifting, and how far each marker sits from its target.

AI Coach

Ask what a result means, read the trend, or prep for your doctor — with Claude, ChatGPT, Gemini, Perplexity or Grok. Plain-language guidance grounded in your own numbers.

Longevity mode · Verith Pro

See your numbers against longevity targets — not just "normal".

Standard ranges say "normal" right up until you cross the threshold into sick. Peak ranges catch the drift years earlier — so you can change course before disease, not after the diagnosis.

Optimal ranges & letter grades
Each panel earns an A+–F grade with a clear "peak" target to aim for.
Standard & Longevity views
Switch between clinical reference ranges and longevity targets in a tap.
AI Coach

An AI coach that actually knows your body.

Ask a health question and Verith assembles a detailed, private prompt from everything it knows about you — then hands it to the AI you trust most, so the answer is grounded in your numbers, not generic advice.

Claude ChatGPT Gemini Perplexity Grok

No two models reason about health the same way. Verith works natively with the leading assistants — pick the one you trust, or ask several and compare, so the depth and quality of your guidance stays in your hands.

Interpret a result, explain a trend, or find the supplement that would help most.
Prep focused questions for your next doctor visit, backed by your own history.
