Coherva

The science of stillness

— and the ancient practices that got there first —

One daily coherence practice.
Grounded in research. Rooted in tradition.

Peer-reviewed neuroscience. Five thousand years of contemplative wisdom. One personalised practice system that connects them — measurably.

What Coherva is

Not a meditation app.
Not a religion. Something else entirely.

Three tools that work together as one coherence system.

Daily Resonance
One science-grounded, tradition-mapped insight each morning. Every claim labelled PROVEN, THEORETICAL, or EMERGING. Sourced. Never overstated.
Daily · Free tier
Coherence Practice
A 4-step daily protocol drawn from HRV biofeedback research and contemplative neuroscience. Tracks your streak, your depth, your trend — over time.
Daily · Free tier
Sacred Library
11 wisdom traditions, fully searchable. Ask your AI Guide about any passage. Compare texts across traditions and see the coherence score. Your journal feeds your recommendations.

How it works

A daily rhythm in four steps

1
Morning check-in
60 seconds. Sleep quality, energy, stress. Optional HRV reading if you have a device. Your Coherva Guide uses this to calibrate today's practice — not to judge, but to respond to where you actually are.
PROVEN — autonomic self-report correlates with HRV
2
Today's coherence practice
Four steps, roughly 24 minutes. Observer Seat quiets the default mode network within 90 seconds. Coherence Breath maximises heart-brain synchrony at 0.1 Hz. Body Awareness activates interoceptive pathways. Insight Integration consolidates the shift into lasting pattern.
PROVEN — HeartMath Institute, McCraty et al. 2015
3
Journal your reflection
What shifted? What arose? Your journal is not a diary — it is data. Your Coherva Guide reads it and connects your lived experience to a passage in the Library, a science finding, or tomorrow's practice. This is the convergence that makes Coherva unlike anything else.
THEORETICAL — affective consolidation via reflection
4
Your resonance arrives
One daily insight, drawn from the intersection of your practice, your reflection, and the tradition most relevant to your current state. Not generic. Not algorithmic. Grounded in what you actually did today.
EMERGING — personalised contemplative recommendation
Every claim is labelled. Every source is cited.
HeartMath Institute
HRV coherence shifts autonomic balance within 4–6 breath cycles at 0.1 Hz. Baroreflex gain increases measurably. Cortisol reduces within 10 minutes of sustained coherent breathing.
PROVEN
Polyvagal Theory · Porges
The vagus nerve carries 80% of its signals from body to brain, not brain to body. Coherent breathing is a bottom-up intervention — the body communicates safety upward to the nervous system.
PROVEN
Contemplative Neuroscience
Sustained attention practice reduces default mode network activity within 90 seconds. The felt sense of stillness in contemplative traditions corresponds to measurable reductions in amygdala activation.
PROVEN

11 wisdom traditions

The same insight arrived
from eleven different directions

Coherva maps peer-reviewed science to the traditions that documented the same phenomena centuries earlier. We treat wisdom traditions as repositories of human experience, not as belief systems.

Questions

The ones worth asking

Is this religious?
No. Coherva treats wisdom traditions as repositories of documented human experience — not as belief systems. We study what practitioners across 5,000 years reported about states of stillness, coherence, and attention. We then map those reports to peer-reviewed neuroscience. You do not need to hold any belief to use Coherva. You need only be willing to practise.
Is the science real?
Yes — and we are specific about what kind. Every claim on Coherva is labelled PROVEN (peer-reviewed, replicated), THEORETICAL (proposed mechanism, not yet fully confirmed), or EMERGING (active research, promising but incomplete). We cite sources. We do not overstate. The HeartMath research on HRV coherence is robust. The contemplative neuroscience is growing. We tell you which is which.
Is this a meditation app?
No. Meditation apps train attention. Coherva integrates attention, physiological coherence, tradition, and personalised AI guidance into a single daily practice system. The practices are grounded in HRV biofeedback research, not mindfulness frameworks. The difference in daily experience is significant.
What does "coherence" actually mean?
A specific, measurable physiological state. Heart rate variability coherence refers to a synchronised rhythm between the heart, brain, and autonomic nervous system — documentable via HRV analysis. A coherence score is not a metaphor. It is derived from RMSSD (root mean square of successive differences) in RR intervals, mapped against a reference curve developed by the HeartMath Institute. We show you the formula. We show you the source.
Do I need a wearable device?
No. The full Coherva practice works without any device. If you have an HRV-capable wearable (Polar H10, Oura Ring, Garmin), it integrates directly and adds live biometric data to your dashboard. If not, a 60-second morning check-in provides enough context for your Coherva Guide to generate personalised insights.
What makes this different from other wellness products?
Three things that no other product combines. First, the convergence claim — that peer-reviewed neuroscience and 5,000 years of contemplative tradition are pointing at the same measurable state. Second, the personalisation depth — your journal feeds your AI Guide, which connects your lived experience to a Library passage from a tradition you may not have chosen yourself. Third, the evidence standard — we label every claim. Most wellness products do not.
