What is The OneDevice?
The OneDevice is a wearable wellness device designed to look like jewelry.
It combines light and sound-based frequencies inside a compact pendant. These signals operate at low intensity and are designed to provide gentle, continuous input while you wear it.
Many people incorporate The OneDevice into their daily routine for moments of calm, focus, or balance.
How does The OneDevice work?
The device emits a combination of near-infrared light, visible light, and sound-based frequencies.
These signals are coordinated by an internal microcontroller that manages timing and output.
The device includes multiple frequency modes that can either run automatically or be cycled manually, depending on your preference.
What’s inside the device?
Inside The OneDevice is a compact system made up of:
- A microcontroller that coordinates light and sound signals
- LED components emitting near-infrared and visible light
- A sound transducer that produces frequency signals
It also includes embedded quartz and shungite elements within the casing.
What frequencies does it emit?
These can either:
- Run automatically in rotation mode
- Be selected manually for a more focused experience
Where is it made?
How do I start using my device?
- 1. Charge the device fully using a USB-C cable
- 2. Wear it as a pendant near your chest
- 3. Pick it up to activate
- 4. Lay it flat to turn off
How do I choose a frequency mode?
Rotation Mode (default)
- Automatically cycles through all frequencies
- Ideal for general, full-spectrum use
Single Frequency Mode
- Place the device flat
- Tap the casing to cycle through frequencies
- Select a specific frequency based on your preference
How long should I wear it?
Many users naturally increase usage and wear it throughout the day.
When should I wear it?
Most people wear it:
- During work or focus time
- While relaxing
- Throughout the day as a background support
Where should I wear it?
Do I need skin contact?
However, it turns off when placed flat, so it may not stay active overnight.
Can I wear it while sleeping?
However, it turns off when placed flat, so it may not remain active while lying down.
Can I exercise with it?
The device is suitable for light activity.
For high-impact exercise (running, jumping), we recommend removing it to prevent damage.
Avoid prolonged exposure to sweat, as this may affect the device over time.
What is Bio-Tuning®?
Bio-Tuning® is a personalization upgrade.
It uses Heart Rate Variability (HRV) to identify a frequency aligned with your autonomic nervous system.
This frequency is then programmed into your device to create a more tailored experience.
How does Bio-Tuning® work?
- Your HRV is measured
- A personalized frequency is identified
- That frequency is programmed into your device
Can I add Bio-Tuning® later?
Yes.
Your device can be returned for reprogramming to include the upgrade.
How do I get my frequency measured?
This is done through a guided HRV session with one of our partner centers.
Details are provided when you choose to add Bio-Tuning®.
How soon will I notice something?
This varies.
Some users notice subtle shifts early, while others describe changes building over days or weeks of consistent use.
Consistency matters more than intensity.
What should I feel?
Some users report:
- A sense of calm
- Subtle warmth
- More balanced energy
Others may not feel immediate sensations.
Is it normal to feel nothing at first?
Yes.
The device works subtly and continuously, and many users notice changes gradually rather than instantly.
Why don’t I feel vibration?
The device does not create strong external vibration.
The frequencies operate internally, which is why there is no noticeable buzzing.
How loud is it?
The device is extremely quiet.
It is usually only audible when placed very close to the ear.
What benefits do users report?
Users commonly describe:
- A greater sense of calm
- Easier transitions into relaxation
- More balanced daily rhythms
Experiences vary and are not guaranteed.
Is the device safe?
The OneDevice operates using low-power electronics similar to everyday wearable devices.
It is designed for daily wellness use within standard safety limits.
Is it a medical device?
No.
The OneDevice is not a medical device and is not intended to diagnose, treat, cure, or prevent any condition.
Can I use it with medical conditions?
Can I wear it during pregnancy?
The device emits low-intensity signals and is generally considered safe for wellness use.
If you have concerns, consult your healthcare provider.
Pacemaker compatibility
Not specifically tested.
Consult your doctor before use.
Battery life
How do I charge it?
Use the included USB-C cable or any low-powered USB-C charger.
Avoid high-voltage or incompatible chargers (such as Lightning adapters).
Charging takes approximately 3 hours.
The LED indicator will turn green when fully charged.
Why does it turn off?
The device includes a motion sensor.
When placed flat, it powers down automatically to conserve battery.
What materials are used?
The device casing is copper-based and finished with different coatings depending on the model.
Inside are electronic components along with embedded quartz and shungite.
Is it waterproof?
No.
The device is not waterproof, though it can tolerate small splashes.
Remove before showering or swimming.
Can I use my own chain?
Yes.
The pendant loop fits most standard chains (approximately 0.5 cm opening).
