Read your Oura data without a medical degree
Your Oura Ring measures a lot. What it rarely tells you is whether today's number is good, bad, or nothing to worry about — for you. Vitra is a desktop companion built to answer exactly that, in plain language, on your own machine.

The problem with a number on its own
“Your HRV is 42.” Is that good? Without context it means nothing. The same 42 can be a great morning for one person and a warning sign for another. What matters is how today compares to your usual — not a textbook average or someone else's ring.
Vitra's whole design starts here: never show a number without telling you what it means. Every metric is paired with your personal baseline, the direction it's moving, and a one-word read you can act on.
One score, one sentence
Open Vitra and the first thing you see is a single readiness score and a plain sentence — something like “a steady day, good for focused work and a moderate workout.” That's the glance. If that's all you have time for, you're done.
Underneath, a short suggestion names today's most useful action and why: “short night, 5h 19m versus your usual 5h 53m.” Real numbers, plain words, no jargon wall.
See where today sits
On every detail page, a position marker shows today's value on a track of your own usual range. A dot lands low, usual, or high, coloured by whether that's healthy for you — green when it's a good sign, warm when it's worth easing off. You read “is this good or bad?” in half a second, and a short line spells out what to do about it.
Tap anything you don't recognise
HRV, SpO₂, REM, VO₂ max, cardiovascular age — hover or tap any term and a small card explains it in one plain sentence, plus why it matters. There's no glossary to go hunting for; the explanation lives exactly where the word appears.
How today connects
Numbers don't move in isolation. Vitra draws the chain — short sleep feeds lower recovery, which feeds a lower score — so you learn the story of your day, not just a pile of readings. Over time you stop needing the app to tell you; you start seeing it yourself.
Built to be trusted, and private
Each reading shows how much history it rests on (“32 nights · strong data”), so you know when to weight it and when to wait. And it's all computed on your Mac or PC from your own data — no cloud account, no health data leaving your machine. The “AI” is research rules and your rolling baselines, not a chatbot you feed your body to.
This is general educational information, not medical advice.
Frequently asked questions
Pedro Thomaz builds Vitra, a desktop app that reads Oura data against your own baseline instead of a population average. He has worn a ring daily for years and reads these same numbers every morning — which is where most of what is written here comes from. Vitra is not a medical device and nothing on this blog is medical advice.
