What is Bio-Tuning®

Your body has a resonant frequency.

A clinically-grounded process that finds the precise frequency at which your nervous system settles into balance — then writes it into the OneDevice you wear, as a frequency that is yours alone.

Every living system vibrates. Using real-time heart-rate-variability biofeedback, a certified practitioner locates the single point where your sympathetic and parasympathetic nervous systems reach equilibrium.

It is not a generic wellness frequency. It is yours — discovered through your own physiology, and built on the forty-year research of Dr. Jeffrey Thompson at the Center for Neuroacoustic Research.

How it works

Four steps. One measurement. Personalized to you.

Have your personal frequency measured by a certified Bio-Tuning® practitioner, then send it to us. We program it into your device and ship it to you, ready to use. Here is exactly how it works.

1
MEASURE
Have your frequency measured

Visit a certified Bio-Tuning® practitioner, who measures your personal frequency in a short session.

2
ORDER
Add the Bio-Tuning® Upgrade

Order The OneDevice with the Bio-Tuning® Upgrade added to your device.

3

Personalized and ready

We program your device to your frequency and ship it to you, fully personalized and ready to use on arrival.

Prefer it done on the spot? We have a limited number of practitioners who can program your device right after your session. Contact us to check if one is near you.

What you feel

Your own frequency, given back to you.

When the signal your body resonates with is reintroduced — worn continuously, all day — three things follow.

i

A return to homeostasis.

Not rest-and-digest dominance — that would only trade one chronic state for another. True balance between both branches of the autonomic nervous system, where the body finally holds its energy in reserve.

ii

Coherence and balance.

Breath, heart, and brain entrain to a single carrier signal. The chaos quiets. Internal rhythms synchronize — measurably, within weeks.

iii

Precision, not guesswork.

Not a frequency someone picked on YouTube. The exact set your nervous system stabilizes on — and only that.

Homeostasis is the prerequisite for healing. Only in balance — with energy held in reserve — does the body awaken its own inner physician.
04

What it delivers

A device that knows you.

Every device plays the same ten frequencies. Bio-Tuning remembers an 11th — yours — so no two Bio-Tuned devices are alike.

Once located, your practitioner writes it in.

Your personal frequency is added to the ten the device already plays — an 11th tone, remembered in the module. From that moment, it emits your frequency continuously, all day long.

i.
A nervous system in homeostasisBalance between both branches — not chronic rest-and-digest — so the body holds the reserve it needs to maintain itself.
ii.
Regulation tailored to youNot a population average. Not a preset. The exact set of signals your physiology resonates with.
iii.
Recovery, calm focus, restorative sleepThe effects clients describe most in the first thirty days.
iv.
A truly personal wearableYour serial, your 11th frequency — remembered in the module. One of one.

Standard Device vs. The Bio-Tuning Edition

Standard OneDevice
  • Plays all 10 universal frequencies
  • The same frequencies for every wearer
  • Passive delivery via sound + light
  • No personalization required
Bio-Tuning × OneDevice
  • Adds your personal frequency as an 11th
  • Programmed specifically for your unique Hz
  • Plays all ten plus your custom 11th, all day
  • Extends your Bio-Tuning sessions into daily life

Once your Bio-Tuning practitioner determines your fundamental frequency, it is added to The OneDevice as an 11th — so alongside the ten universal tones, the pendant also plays your own, all day while you wear it.

The science

Forty years of research, in the device you wear.

Bio-Tuning® is the life’s work of Dr. Jeffrey Thompson — and the same frequencies power his library of personalized audio programmes.

Companion programmes · mybiotuning.com

Personalized brainwave-entrainment audio, on the same frequencies.

The frequencies we encode into your OneDevice also power a library of practitioner-calibrated audio programmes — for sleep, focus, recovery, meditation, and deep nervous-system work.

Wear the device all day. Press play when you want a deeper, targeted session. Each reinforces the other.

For practitioners

Bring the most personal frequency therapy to your practice.

No proprietary chair, no clinical buildout. Acquire the HRV instrument, complete the certification, and deliver an encoded OneDevice to every client.

Offering Bio-Tuning® transforms The OneDevice from a universal wellness wearable into a precision instrument — calibrated, individual, and deeply healing.

The process requires no proprietary chair and no clinical buildout. You acquire the compact HRV measurement device developed through Dr. Jeffrey Thompson's research, complete the certification, and you are equipped to assess, programme, and deliver a uniquely encoded One Device to every client who walks through your door.

Each session is a single fee, paid by the client. The encoded device continues working long after they leave your clinic — a lasting wellness tool that keeps your practice present in their life every day.
