Making health understandable for everyone
We turn overwhelming data into clarity — so people can finally take control of their wellbeing
Why we created Welltory
The gap between data collection and understanding is why fitness trackers have a massive abandonment problem: one-third of owners quit within six months, and more than half eventually stop using them entirely.
People are drowning in health data they can’t understand. Every day, millions track their steps, heart rate, sleep, and workouts. The numbers pile up, but the understanding doesn’t. What does it mean when HRV drops? Is 7,000 steps enough for long-term health? Why does sleep feel unrefreshing even when the app says it was good?
We built Welltory to solve this problem
We’re an all-in-one app that transforms overwhelming data into actionable insights. Using HRV analysis, validated algorithms, and data from 17 million users, we show what’s really happening in your body — and what to do about it.
Since 2016
We’ve been on a mission: shape an ecosystem that helps 100M people measurably improve their health with science and technology that serve each individual personally.

Our team
In 2016, Welltory started out small but with a mighty mission in mind:
To help people stay well for a lifetime with science and technology that serve each individual personally.
After 10 years, our team has grown to 100+ people serving 17 million users worldwide. We’re spread across time zones, but we’re connected by something deeper than Slack channels.
We’re builders and scientists. We develop algorithms validated against medical-grade equipment. We publish in peer-reviewed journals and collaborate with institutions like Harvard Medical School, Johns Hopkins University, and University College London.
We’re designers who believe complexity can be beautiful. We believe beautiful design isn’t decoration; it’s how we make hard-to-understand science instantly understandable. We obsess over details because we want you to glance at the app and instantly understand what’s happening in your body.
We’re product people who listen. We interview users with chronic illness. We talk to athletes optimizing performance. We hear from exhausted parents, burned-out professionals, people recovering from COVID, people just trying to feel like themselves again. Every conversation shapes what we build.
We’re using AI to push the boundaries of what’s possible. We’re exploring how machine learning can detect patterns humans might miss, predict health changes before symptoms appear, and personalize insights even more precisely.
We’re close when you need help. We’re not just troubleshooting technical issues — we genuinely care about helping people get value from Welltory.
What connects us isn’t just the work —
it’s why we do it
We believe understanding your health should be accessible to everyone, and that people deserve better than an industry that profits from their confusion
