It was a great experience. I didn’t feel I was alone in my journey to health. They offered help in explaining the results. No regrets!

So far I’m really happy with the app and the explanations and recommendations it gives.I’ve done 3 blood tests and having it all in the app motivates me to take better care of myself especially in the areas I need it the most. Super cool that it compares them all side by side.

I thought about subscribing for a long time. After my husband’s annual checkup, where he paid $700 (and we have insurance, by the way!), I finally made the decision. He is a pretty healthy man, but they tested only 15–17 biomarkers, which didn’t give us a full picture of his health. That’s when I realized this wasn’t the approach I wanted for myself, and I finally subscribed to Function Health. I’m very happy I did. The amount of information I received about my health was on a completely different level. Now I recommend Function Health to my friends.

I appreciate the ease of getting the appointment, the instructions as to what I must do before the appointment. The only thing I find lacking is the ability to share the reports with my doctor. Maybe I don't know how buy it would be nice to be able to print or email the results.
