How to get your OneDevice Bio-Tuned®
Get measured once. Wear it every day.
Have your personal frequency measured by a certified Bio-Tuning® practitioner, then add it to your OneDevice in the OneApp — no need to send your device anywhere. Here is exactly how it works.
For customers who have already added their personal frequency — charging, wearing, turning it on and off, Personal Frequency Mode, and care. If you have not been measured yet, start with the three steps below.
How it works
Three steps. One measurement. Yours for good.
Get measured
A certified Bio-Tuning® practitioner finds your personal frequency in one short session.

Already Bio-Tuned®? Your quick-start guide
Your device now carries your own frequency.
This guide is for customers who have already been measured and added their frequency to their OneDevice. Six simple steps, from first charge to daily wear.
Download, print, or save it to your phone. Keep it with your device for charging times, Personal Frequency Mode, and care instructions.
Charging takes 2–3 hours — the LED blinks red while charging and turns green when full, lasting up to 90 hours. Wear it as a pendant, or keep it near you through the day.
On start-up it runs its default rotation, then four ascending cycles of your personal frequency — base, one, two, and three octaves higher — shown by the white light, looping automatically.
Hold the device horizontally and tap once at a time to set a single Solfeggio frequency; tap until you return to Default Mode. Water resistant, not waterproof — take it off before showering.
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 adds it to 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.
Standard Device vs. The Bio-Tuning Edition
- Plays all 10 universal frequencies
- The same frequencies for every wearer
- Passive delivery via sound + light
- No personalization required
- 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 a certified Bio-Tuning® practitioner measures your fundamental frequency, you add it to your OneDevice in the OneApp as an 11th — so alongside the ten universal tones, the pendant also plays your own, all day while you wear it.
Unlock Your Frequency →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.
Personalized brainwave-entrainment audio, on the same frequencies.
The frequencies on 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.
“Every nervous system has a fundamental frequency — a single tone at which it resolves into balance. The work of forty years has been to locate it, and now to wear it.”

Practitioners already working with the autonomic nervous system, HRV, breathwork, or vibroacoustic therapy. Bio-Tuning slots cleanly into existing protocols.
The compact HRV measurement device, the encoding interface that writes to the OneDevice module, four days of in-person training, and a listing on our practitioner directory.
Direct relationship. We do not take a percentage of the encoding session. We supply the device, you deliver the calibration, the client wears the result home.
A wearable, calibrated to you.
