The Science Inside
Oruna turns a handful of quiet signals into one clear answer each morning: how hard should you go today?
Heart rate variability
Measured overnight, HRV shows how recovered your nervous system is. A low reading means Oruna softens today's plan.

How Oruna Learns You
- 1
Week 1
Baseline
Oruna watches quietly. It learns your resting heart rate, sleep window and how you respond to your usual sessions.

Week 2
Patterns
It starts to spot links, like how late dinners shorten your deep sleep or how Monday runs feel harder after busy weekends.

Week 4
Your model
A personal coaching model takes over. Plans now shift daily, and check-ins get shorter because Oruna already knows the answer.

Ongoing
