Three vital rhythms, individually calculated from the moment you were born.
Physical, emotional and intellectual are the names of the classic model’s three cycles. The chart shows their mathematical position, without measuring your physical or psychological state.
A daily portrait of your personal rhythmic trend.
Discover your biorhythm value in each cycle, what it means, and how it will evolve over the next 7 days. A reading built on your own birth data, because every interpretation is calculated individually.
A historical model for exploring personal rhythms. Precision in calculation does not establish that these cycles describe energy, emotions or cognitive ability.
Discover your tune with the people who matter.
Partners, friends, family, colleagues, acquaintances: every bond creates a unique dynamic between your rhythms and theirs. Our system analyzes it through biorhythms.
The rhythm of the physical dimension: energy, vitality and the body's capacity for expression.
The rhythm of the emotional dimension: sensitivity, perception and the movement of your inner world.
The rhythm of the mental dimension: clarity, focus and the capacity to understand and process.

Explore the movement of your Vital Rhythms
Watch how the three cycles unfold over time and how their variations shape your personal trend. Each rhythm follows its own periodicity, in a continuous interplay between body, emotion and thought.
Over a century of research into time, cyclicity and the individual.
We present the history of the classic model separately from experimental research on biological rhythms. A historical tradition is not the same as scientific validation.
Two rhythms, the same day.
An example of charts and an interpretive reading generated from the model. Percentages do not measure relationship quality.
The chart shows two conventional curves for each cycle on a chosen date. Their distances describe a mathematical comparison; they do not establish how you will feel or which day is best for a decision.
Harmony in everyday life: this is a precious combination for a couple. You're aligned across all three planes: physical, emotional and intellectual. You have the chance to do things together, feel close, and understand each other with ease. You're, potentially, a great team. The one thing to watch for is the total synchrony: when one of you goes through a low moment, the other is likely going through it too. It's not a flaw, but a trait worth knowing. You can learn to recognize these moments together and give each other room, without expecting too much from one another. You have everything you need to build a stable, deep relationship. Harmony is never a given: it's an opportunity to nurture with presence, listening and everyday care.
