About
I am Albert Arnó, MD, PhD — a physician working in health technology from Barcelona, Spain.
In 2000 I founded onmedic, a studio that builds software for hospitals, research centres, laboratories and medical practices. Most of that work is confidential and always will be: clinical data systems, research software, the infrastructure that sits underneath other people's names. It taught me the thing that still governs how I build — that a health record is not a preference, and that the safest place for one is the smallest number of places.
Most of my own building lately has gone into AnalyticsZone, a family of sports and health analytics apps. They read what your watch already recorded and compute the models a coach would actually use: critical power and W′ balance, critical swim speed, gait asymmetry, heart-rate variability, training load. Every model is a published one, cited on the page that explains it, and all of it is computed on the device rather than on a server I control.
Alongside that there is Pelvisana for pelvic-floor education, Velytra for coaches and their athletes, and DoctorMi for the unglamorous problem of non-urgent clinical messaging.
What I will and will not claim
I am a doctor, and the software I write touches health data, so it matters that the line is explicit. Nothing I publish here or ship in an app is a diagnosis, and none of it replaces a clinical assessment. What these tools do is compute defined metrics from sensor data and explain, with citations, what the literature says those metrics mean — including where they stop being reliable. Where I do not know something, the honest version is on the page.

albertarno.net published 194 posts between 2012 and 2019 that I did not write: an IFTTT recipe reposting my Feedly bookmarks. The text belongs to the publications that wrote it, so none of it has been republished here — but nothing has been hidden either. The complete archive lists every one of them, linked to its capture in the Internet Archive, and Restarting this blog, seven years later explains the whole thing.
