Simply the best

I've been doing keto for many years and this device is fantastic! No more capillary blood samples or urine - I can test on the go and know exactly my level of ketosis.

Cannot rave enough about your product! By knowing my Ketosis level at all times I feel I am in control of my weight loss program. Recipes are great I’m down 20lbs in the 1st month!!!

Game changer

I love that I am able to monitor my ketone levels often throughout the day. This helps me to see how different foods affect my levels and tweak my diet as needed. Love it!!
