The One Frequency device has become one of my favorite biohacking tools—I genuinely never leave home without it. Using the One app to program custom frequencies is a game changer. One of my favorite features is the programmable circadian rhythm setting, which automatically adjusts throughout the day to support my energy, focus, and overall well-being. This is far more than a simple pendant. It uses light, sound, and frequency to create physical sensations throughout the body, and it also includes biofeedback capabilities. The app can analyze HRV and voice patterns to help personalize the frequencies that may best support me at that moment. I also regularly use the meditation and focus programs in the app. The technology feels incredibly advanced, yet it is simple and convenient to use. Another major benefit is that the pendant does not rely on Bluetooth. It is enclosed in a Faraday cage designed to block EMF and communicates with the app through a unique vibration-code system. For anyone interested in frequency technology, personalized wellness, meditation, focus, and advanced biohacking tools, the One Frequency device is definitely worth exploring.

I have used every kind of frequency device out there. This is the only wearable frequency device that exists and it’s incredible. I feel more balanced, centred, and sleep quality has improved considerably. I love my one device and won’t go without it.

Ich hatte mich sehr auf mein One Device gefreut und freue mich umso mehr, dass ich meine Bewertung heute aktualisieren kann. Der Start verlief leider unglücklich. Das ursprünglich gelieferte Gerät war defekt und der gesamte Austauschprozess zog sich länger hin als erwartet. Rückblickend glaube ich jedoch, dass manche Situationen einfach unglücklich zusammenkommen und sich nicht vollständig vermeiden lassen. Besonders positiv hervorheben möchte ich, dass One Device den Fall letztlich sehr engagiert begleitet hat. Ich hatte eine feste Ansprechpartnerin, die mich durch den gesamten weiteren Prozess begleitet und sich zuverlässig um mein Anliegen gekümmert hat. Auch die entstandenen Zollkosten wurden ohne Diskussion erstattet. Heute ist mein Ersatzgerät angekommen und ich bin rundum zufrieden. Das Gerät funktioniert einwandfrei und ich freue mich jetzt darauf, endlich mit dem One Device durchzustarten. Vielen Dank an das Team für die Bemühungen und dafür, dass am Ende eine gute Lösung gefunden wurde.

Hi Victoria, Thank you for sharing your experience so openly. We're truly sorry that your experience fell short of your expectations. We recognize that the delays in communication added to your frustration. While we've recently experienced a significant increase in customer inquiries, that's not the standard we hold ourselves to. We're continuing to invest in our support team and processes so we can better support our community. We also appreciate you bringing your concerns about the replacement to our attention. We'd like to reassure you that we do not ship or sell used devices, and every replacement is intended to be brand new. We've already escalated your case internally, and our quality team is reviewing it thoroughly to understand exactly what happened and determine how we can prevent it from happening again. Thank you as well for acknowledging our team's efforts to resolve the customs charges. Although we're pleased we could assist with that, we understand it doesn't change the overall experience you've had. Our team has already reached out to arrange another replacement, and we'll continue working with you until this matter is fully resolved. We're committed to restoring your confidence in both our product and the service you receive from us. Thank you again for your feedback. We appreciate the opportunity to make this right.
