Four check-ins a year. One doctor who follows your trajectory.
Every 90 days: a 10-minute at-home blood test, 10 blood values analysed at an EU-certified lab, a 30-minute call with your CHIRAYOU doctor, and a written plan you can act on this week.
Four quarterly check-ins roll your 20 markers into one number: how many healthspan years you're ahead of your baseline.
Illustrative example · model-based estimate
One loop, repeated every 90 days.
Test, Plan, Act - then around again. The blood test isn't step one of four; it's the first turn of a cycle that compounds the healthspan years you gain.
Test
Measure what mattersA nearly painless at-home Tasso+ draw, plus your wearable and functional data, refresh all 20 markers across four systems - distilled into one healthspan score.
- 10-value blood panel, EU-certified lab
- Wearable + functional signals a draw can't see
- One score, not a flood of numbers
Plan
Decide with your doctorA 30-minute call with the same doctor every quarter turns your numbers into two or three concrete moves for the next 90 days.
- The same doctor, who's seen your history
- 2–3 interventions tied to your markers
- Your written plan, in the app
Act
Live it for 90 daysYou follow the plan while the app tracks progress between draws. Then the loop comes back around - and the next test shows what actually moved.
- Guidance + nudges between tests
- Trendlines, not one-off snapshots
- Each loop builds on the last
Four systems. 20 signals. One picture of you.
We track the four systems that drive how long you stay sharp, strong, and steady. Every quarter we measure the biomarkers behind each system, plus lifestyle inputs.

A trendline, not a snapshot.
One test tells you where you are today. Four a year tell you which direction you're moving - and let your doctor adjust before a number drifts out of range.

Not all health programs are created equal.
A healthspan program needs three things to work: continuous data, real time with a doctor, and a plan that adjusts each cycle. Here's how the options stack up.

One-time setup. The hardware that fills the days between blood tests.
The lab gives you 10 blood values every 90 days. The starter kit captures what happens in between - sleep, pressure, weight, grip - so your quarterly call has a continuous signal to read, not just two snapshots. Required for Annual and Quarterly plans. Configurable at checkout if you already own pieces.
