Great insights into metabolism

Love the insights this app offers to help you understand the science behind your choices and personalized recommendations based off real time measurements.

Impossible to cancel and contact them

App won’t allow me to cancel, chat feature does not work, website contact info goes to a dead link and have no phone number to call. They make it as difficult as possible to cancel their recurring membership.

Problems

Too complicated to know what to do. The onboarding is like reading an encyclopedia. Their education is like mini TikTok videos. Crazy for someone who just wants to read and understand.

Also, never got the initial email that had the registration code - so can’t use the device.

Also they only support in a narrow East Coast hours window. So if you dare to purchase their product from another time zone - heaven forbid you try to get support after 1 pm Pacific on a Friday — you are hosed!!

Latest update makes it REALLY bad.

The latest update causes it to log me out and disconnect the device every single time it is used. When it worked it was great, but if I have to log in and reconnect the device every time I want to use it I will probably throw it away and just go back to timed fasting.

Lost internet after app update

Still waiting for update - UK based awaiting support to open - 1pm UK is a new day

Reloaded app - data OK

Support chat lost - the app now works it was my iPhone that didn’t support the app update - worked on my wife’s iPad old May 2025 version
