One L1fe Waiting list

A Digital Twin
for personalized
health coaching.

One L1fe is the AI app where science meets your own body.

Launching in 2026 in the App Store and on Google Play.

The Digital Twin home screen of the One L1fe app: one figure in the center, six hubs around it.
Why we built it

We all have only one life, but not the personalized support to protect our health so we can live our best life.

Your watch tracks your training and sleep. A lab reads your blood. A kit reads your microbiome. An app counts your meals. Each one reads you against an average, and none of them reads the others.

A resting heart rate of 48 means nothing next to a population chart, and a great deal next to your own last six months.

One L1fe reads all of it as one, and turns it into what to do today, tomorrow and for life.

How it works

A Digital Twin built from your data. A team of AI coaches turns it into decisions for how you perform today and the health you keep for life.

  1. 1. Connect your data

    Connect your wearable. Upload your blood panels, microbiome and genomic tests. Add your Health Record and log what you eat. A lab report becomes structured biomarkers, and you check them before they go into your record. Shown: the Longevity hub, every marker against its reference range. Every hub has its own coach, right under the data.

  2. 2. The Twin learns your baseline

    The Twin's screen is your summary, one tile per hub: today's energy, blood markers out of range, last session, food, weight, sleep, biological age and more, all on one screen. Every reading is measured against your own history, not an average.

  3. 3. Your coaches plan your days

    Your coaches turn the Twin into a plan. Monday morning: your brief says an easy run and what to eat before it. Evening: dinner suggestions that fit the session. Next week: a note that your blood test is due. And a training plan that runs to race day, adjusting as your data changes. Shown: week one of a marathon plan.

Six coaches, one table.

  • Sleep
  • Exercise
  • Nutrition
  • Resilience
  • Longevity
  • Health Record

Each hub has a coach of its own, and each coach reads the same record from its own side. Ask one, or bring up to five to the Round Table and they answer together. Add your own hubs for what matters to you.

Each screen plays as you scroll, forwards and back, at your own pace.
