The reduced membership price is great! Labs come back quickly. Would like a little more guidance from the clinician. I have been searching for my root cause for several years and have not been able to relieve the symptoms.

I have been generally ◡̈ with my experience so far! The pricing is far. The app is super easy to use and shows useful information. the customer service has been quick to reply to my questions. one little feature i wish i saw but maybe im missing is i wish you could filter data by test date. once you clikc on a test result that is in the "new" tab. its not there anymore. Small thing. but everything else has been great.
