Bond Ring Evo™, along with Bond Ring, are the only two smart rings build for sports. Why? Imagine trying to track a heart rate of 150 bpm—that’s more than two beats per second, using a wearable that reports heart rate once every minute or, worse yet, once every 5 minutes. Still wondering why Bond Ring is a game changer?

Check this out.

True UV and Light sensing

Bond Ring Evo™ is the only wearable to accurately sense UV-A and UV-B levels (not equivalent UV), alongside ambient light levels.


The ability to sense UV allows the Bond Ring to estimate equivalent Vitamin D levels. That’s definitely NOT a replacement for a blood panel, but it sure can help you understand if those ADHD-like symptoms are due to living in a ‘cave.’ (Note: This is not intended for diagnosing ADHD.)

With that said, you could also set up simple workflows on the Bond Ring to call 911 when there’s UV exposure—just kidding! How about setting it up to send a notification to apply sunscreen? And if you’re into tanning, consider creating a workflow to set maximum time alerts for UV exposure to prevent you from roasting.

The Bond Ring is the culmination of a pursuit of excellence, bringing together the world’s most advanced technology in wearable computing, material science, and vital sign sensors. When you compare the same features between Bond Ring and any competitor, the difference is in the components — the world-class partners behind every component.

Being part of the prestigious Dassault Systèmes startup program allows us to deploy the world’s most advanced CAD software for Bond Ring Evo™, Dassault Systèmes CATIA V6.

The same software is used to build space rockets, medical implants, and nearly every daily driver or hypercar.

Bond Ring Evo™ deploys one of the world’s most power-efficient motion and pressure sensing solutions from Bosch.

Participation in the Altium Designer accelerator program allows us to deploy one of the world’s most capable electronics designs for Bond Ring.

Vital sign sensing powered by AMS OSRAM, Germany.

FDA and regulatory compliance powered by RCA - A Nelson Labs Company.

The world’s first smart ring to deploy the cutting-edge SECORA™ X tap-and-pay solution from Infineon.

Cutting-edge IP behind the Bond Ring is secured by Finnegan. The global leader in intellectual property.

HIPAA compliant authentication and security powered by Auth0.

A product of Wilder Tech Inc. © Wilder Tech Inc. All key innovations in the Bond Ring™ and its design are patent-pending with the USPTO. Bond Ring™, TrueTemp™, LifeDrive™, Bionic Feedback™, Ballistic Sampling™, Future on Your Finger™, and Pinnacle of Wearable Advancement™ are registered trademarks.


^The Bond Ring is not a medical device and is not intended to diagnose or treat any medical condition. All features are designed solely for wellness purposes. However, the Bond Ring is progressing toward clinical trials and may eventually receive FDA clearance to diagnose various conditions, potentially transitioning to a medical device in the future. When referring to clinical-grade sensors, we mean certified and tested sensors designed for medical devices; this does not classify the Bond Ring as a “clinical” or “medical” device. Our primary objective is to deploy the best suite of sensors to enhance user awareness of personal wellness and vital body metrics.


*Sleep apnea is classified as a medical condition. Bond Ring and Bond Ring Evo are not medical devices and are not intended to diagnose or treat sleep apnea. The sensors measuring respiration rate and blood oxygen levels during sleep are designed exclusively for insight and awareness. If you suspect you have symptoms of sleep apnea, consult your primary care physician, a sleep specialist, or another qualified medical professional for diagnosis and treatment. This statement does not constitute medical advice.


¹When we refer to “perpetual” or “maintaining perpetuality,” we do not imply that the device can operate indefinitely without any external energy under all circumstances. The LifeDrive modules in devices such as the Bond Ring FE and Bond Ring PRO battery packs generate power from ambient light and/or the natural flow of body heat to the surrounding environment (or vice versa). These rings utilize intelligent power-management algorithms that enable them to operate for up to three months in “maintain perpetuality” mode, even without exposure to light and/or when worn in environments that remain within ±5°C of body temperature. However, such conditions are considered highly unrealistic in typical use. If you anticipate wearing the Bond Ring Perpetual products in environments matching these parameters, please note that the rings/battery packs will cease functioning after approximately two to three months and will require exposure to natural light to recharge. Depending on the setting the Bond Ring PRO can easily run through the battery pack in less than 12 hours and hence we do not recommend using LifeDrive Battery Packs for such heavy use and it would be recommended to use standard or plus battery pack(s).


Specifications for the Bond Ring PRO and Bond Ring Evo are subject to change. Feature additions specific to the Evo may occur, and any such updates will be announced in advance. The Bond Ring PRO may receive feature additions or modifications without prior notice before it becomes available for reservation on the website, and with notice once reservations go live.


¹Bond Ring Evo, unlike Bond Ring, measures body composition across the upper body using our proprietary algorithm to estimate equivalent variations in body composition. Measurements from both Bond Ring and Bond Ring Evo are not intended for medical diagnosis or treatment.
