About OneVitals

We built health that
watches with you.

OneVitals turns the quiet rhythm of daily at-home readings into early signals — for families looking after someone, and the clinicians looking after them. This is who we are and why we started.

Our mission

Most health crises don’t arrive overnight — they build, one quiet reading at a time, until someone finally looks.

We exist to make those readings impossible to miss. By turning a thirty-second morning routine into a shared, watched timeline, OneVitals gives families and care teams the chance to act on a trend while it’s still a trend — not after it becomes an emergency.

Our story

From one kitchen table to two continents.

Five years of building the same discipline we ask of our customers — show up every day, and watch the line.

  1. 2021

    Founded at a kitchen table

    OneVitals started in Lisbon with a single blood-pressure cuff and a spreadsheet, after a founder’s father landed in hospital from a trend nobody was reading.

  2. 2022

    First family pilot

    A Porto pilot paired a cuff, an oximeter, and a scale on one shared timeline. Families caught two early decompensations in the first month.

  3. 2023

    Clinicians joined the loop

    The home app connected to a clinician dashboard, letting a single nurse watch hundreds of patients’ trends without extra appointments.

  4. 2026

    Watching across two continents

    Today OneVitals reads vitals every day and surfaces the few changes each week that actually need a human to act.

What we believe

Three ideas behind every decision.

A change should be noticed

A reading is only useful if someone sees it in time. We design for the moment a trend turns, not the chart it ends up on.

Calm, not alarm

We surface the few signals that matter and stay quiet the rest of the time. Trust is built by not crying wolf.

Care is a circle

Patients, families, and clinicians see the same timeline. No one is left guessing what everyone else already knows.

The people
