Know your numbers. Own your health story.
Welna reads Apple Health with your permission, redacts identifiers on your device, and turns ninety days of signals into plain-language reads — and the questions worth bringing to your clinician.

Three steps, and your numbers make sense.
No new wearable, no spreadsheets. Welna works with the Health data already on your phone — and never asks for more than it needs.
Connect Apple Health
Grant read-only access to a handful of health streams. Welna reads what's already there — nothing new to wear, nothing to log by hand.
Redacted on your device
Names, dates and IDs are stripped locally before anything is sent. Only normalized summaries — never raw records — leave your phone.
Read, and prepare
Plain-language daily reads, deviation watches, and guided workflows — each one ending in questions for a clinician, never a diagnosis.
Your account Sign in with ChatGPT, or bring your own OpenAI API key. Welna never holds your credentials — and never charges you for someone else's tokens.
Not a black box — a transcript you can follow.
Every workflow is a guided agent that pulls your real numbers on demand, redacts before it reaches the cloud, and shows each step as it happens. Nothing is hidden, and nothing leaves un-redacted.
Ask about afternoon fatigue
Two weeks of afternoon tiredness with occasional headaches. Worth asking whether sleep timing, hydration, or screen breaks could play a role — a question for your clinician, never a conclusion.
Apple Health exposes dozens of signals. Only a handful carry real longevity evidence.
And the evidence is as much about how you read them — baselines, trends, regularity — as which you read. Welna ranks them, and reads each the way the science asks.
Cardio fitness — read as a trajectory across your own bands, not a single number.
Sleep regularity — when you sleep matters almost as much as how long.
Privacy, stated as architecture.
Not a promise in a policy — a property of how Welna is built. Redaction happens on your device, before the first byte leaves it.
Summaries are sent to OpenAI (GPT-5.5) under your own account to prepare briefs. They're used only to return your result — never to train models. Redaction is automated, so Welna always asks you to review your own text first.
Four ways to walk in prepared.
Each workflow turns your notes and ninety days of signals into something you can hand to a clinician — questions, not conclusions. Every brief ends the same way: not medical advice.
Prepare for your visit
Turn recent signals into focused questions for your next appointment — with the trends that prompted them attached.
Make sense of results
Plain-language reads of lab and test results, set in the context of your own ninety-day baseline — never alarm language.
Review your medications
A calm summary of what you take and what to ask about — interactions and timing worth raising, gathered in one place.
Summarize a document
Scan or paste a letter, report or discharge note. OCR and redaction run on-device, then Welna distills it to plain language.
Cadenced reads, in plain words — and quieter when nothing changed.
The interpretive heart of Welna. Every figure, streak and trend is computed entirely on your device — offline, with no consent gate — straight from your own Apple Health series. No streaks to chase, no badges, no alarm language. The strongest warning it gives is your body may be working on something.
You slept 7.1 hours — your best week this month. Overnight heart rate held inside your usual band.
You're tracking ahead of your usual pace by this hour. On days you walked at lunch, your afternoon dip was milder.
A steady day, in range. A bedtime around 11pm would keep this week's sleep timing consistent.
Know your numbers. Own your health story.
Ninety days of signals, redacted on your device and read in plain language. Walk into your next visit prepared.
