The New Technology Behind BIOSENSE™ Helps You Succeed By Providing All Day Feedback While Monitoring Your Ketone Levels

ACEs Reading

Published studies and our own clinical research has shown that blood and breath ketones are closely related. While the correspondence is not 1-to-1, knowing your breath acetone concentration does allow us to make educated predictions about your blood ketone levels.

Color Indication

The BIOSENSE™ device and mobile app put your measurement into context by providing a color indicator along with your ACEs reading. The vertical black bar on the results screen indicates where your measurement falls on the overall spectrum of ketosis.

Easy Synchronization

BIOSENSE™ stores up to 100 measurements directly on the BIOSENSE™ device and automatically transfers the data to the LIFE apps, as well as the  BIOSENSE™ app on your phone.

Hear From Our Customers

Measuring ketone production can be a pain. I’ve recently been testing a new device called BIOSENSE™ that will change this. It’s a scientifically validated, highly accurate breath ketone monitor that makes it easy to test your ketones throughout the day.

I’m now recommending it to all of my patients that are fasting or doing ketogenic diets, and I’m using it myself. Check it out!

I love this product! BIOSENSE™ is easily the most affordable, accurate and pain-free keto tester that I’ve used. I am a 50 year old wife, mother of four and a travel and sports enthusiast. I take an active role in my well-being and BIOSENSE™ helps me fine-tune my Keto diet. Since starting Keto, I have lost 30lbs and kept it off for several years. My key to success on keto is tracking my ketone levels. With BIOSENSE™, I can track my levels without overpaying for expensive blood strips and meters. Plus, no more painful finger pricks!
