The One is a wearable biotuning device that uses sound, light, and vibration therapy to help your body return to its natural bioharmonic state. It combines ancient frequency wisdom with modern tech and crystal energy — all packed into a beautifully designed piece you can wear every day.

OneDevice comes with a 1-year warranty and a 90-day happiness guarantee. If you don’t love it, return it for a full refund, no hard feelings. Return shipping is usually at your cost.

We process orders in 1-2 business days and ship worldwide from Miami or Los Angeles (depending on what’s closer to you). Delivery typically takes ~7 days. International customers are responsible for any customs duties.

The One emits specific frequencies of sound (Solfeggio Frequencies), near-infrared light and visible light of specific frequencies. In addition, it contains shungite and clear quartz crystals, which are activated through vibration, amplifying their effects. The combination of shungite and copper provides protection from EMF pollution and electro-magnetic radiations. The quartz inside is an amplifier of your intention. These elements work synergistically to support cellular regeneration, emotional balance, and energetic alignment.

Most people who are sensitive and in touch with their bodies, feel the difference right away. They report a sense of calm, warmth, or even slight tingling as they put it on. Others don’t feel the difference, but notice the results with time. Our customers have reported feeling less stressed or anxious, more grounded, focused, relaxed, calm, energized and more in tune with their body. Most women who wear it reported experiencing significantly milder PMS symptoms. Some people with serious neurological disorders experience complete absence of symptoms. However, everyone’s results are different, since One adjusts to what your system needs most.

Some people feel a shift immediately. For others, it takes 1-2 weeks of consistent use.

Yes. The One is based on well-researched modalities like photobiomodulation (light therapy), vibroacoustic therapy, and bioresonance. You can view some of the peer reviewed studies on our Science page. While mainstream medicine is just beginning to catch up, frequency-based healing has been used by ancient cultures for millennia — and is now being validated by biology and biophysics.

Just wear it like a necklace. You can activate specific frequency programs, or let it run on auto-mode.

You can use the cord we included in the package or any other low-powered USB-C charger. It takes about 3 hours to fully charge. Once charged, the LED will glow green until you unplug it. Once unplugged, it will switch to regular rotation mode. A full charge lasts approximately 70 hours.

To turn it off, simply lay it flat with either side down — the internal sensor will power it down after about 3 seconds. To turn it on, just pick it up.

Absolutely. The One is non-invasive, drug-free, and safe for daily use. It is absolutely safe for everyone. There are no contraindications or side effects. It simply emits very light sound and vibration at very subtle amplitudes (i.e. brightness and volume).

You can, however, the sensor inside OneDevice makes it turn off when in horizontal position, so chances are it will turn off. We recommend placing it near you in a vertical position.

Yes. The One is portable, lightweight, and airplane-friendly. Perfect for jet lag, stress, and staying balanced while on the move.

The One features a curated library of Solfeggio frequencies. You can select targeted programs for sleep, focus, mood, detox, and more.

The One is built with a copper casing, clear quartz, shungite and state of the art electronics. Every material was chosen for its energetic conductivity and harmonizing effects.

Yes. While the One is not a medical device, many users report support with anxiety, adrenal fatigue, brain fog, low energy, and emotional imbalances. It helps your system realign so your natural healing processes can do their job.

Think of The One as a synergistic tool. It amplifies the effectiveness of other practices — whether it’s breathwork, cold plunges, red light, or nootropics. It’s not about replacing, but enhancing.

Yes, it's inspired by the principles of quantum biology and energy fields. Everything in your body is frequency. The One helps you resonate with your optimal blueprint. It re-tunes our physical and subtle bodies (Etheric, Astral, Mental, Causal) to a more expanded parallel reality, allowing us to shift to a higher, fuller version of ourselves.

100%. In fact, The One can deepen your meditations, open heart coherence, and elevate states of consciousness. It's a favorite among meditators, healers, and seekers.

It is not water-proof, however it is water-resistant. Please take it off before taking a shower.
