Poor Customer Service

Used it for one year. Then I was auto charged for year two. I canceled and ask for a refund as soon as I saw the charge. However since it was three weeks after the charge they only refunded 67%. I explained that I never received the renewal notice and to please reconsider. They refused to give back any more money citing the costs to operate their website. They kept a third of my money for three weeks into the year. Will not be signing up again.

Stoked on health app

Function health has provided me with all of the necessary blood testing in order to help check my labs, and then it dues an amazing job of providing you with the results, and what are within range and out of range.

Crashing

Updated app, and now it just crashes to a black screen despite closing and opening 3 times
So it’s literally useless. Before this update it was awesome

Life-Changing

This Function Health App is incredible! I do my labs, then I get a wealth of information AND the protocols for how to get and stay healthier! Meal Plans, Supplements and Foods to enjoy/avoid, exercise plans, whole body plans. And the ability to chat with an AI doctor. I am so pleased with my experience and I may gift this to my adult children! <3

Year 2 & loving it!

I just signed up for year 2 with Function Health and I love it! I have recommended it to so many of my friends as I find it incredibly helpful to track my overall health as I age. Our children also do it as it gives them such a clear picture of their health and they’re young enough to change bad habits. We will all be continuing to do this without a doubt! Best $365 we’ve ever spent!

Its all AI no human Dr reviewing

When you flag that the summary of your blood work doesnt make sense - there are no humans to address it - you get AI pretending to be human messaging you and telling you - you can book an appointment and when you tell them when you're free to talk - the AI can't handle it and cant respond. So your summary is wrong and there are no humans involved or they are really bad employees who should be fired.

Not Built for Women!!

Update: nearly two months later I still haven’t been able to get the cycle tests. Labs aren’t open on weekends and walk in only. Very difficult to drop everything to go wait at quest and hope to be seen. Customer service confirmed they prioritize people with appointments.

I really wanted to love Function Health because the concept is great, but my experience with has been disappointing.

If you have irregular menstrual cycles, it doesn’t seem like they have a clear process for handling it. I had to repeatedly explain my situation, and instead of addressing my actual questions, I kept receiving canned responses that didn’t apply. I was passed between multiple agents, and each one seemed to respond without reading the conversation history.

My questions were about how my lab orders had changed, but I repeatedly received generic explanations about hormone testing that had nothing to do with what I was asking. For a premium membership, I expected personalized support and continuity, not to start over with every new agent.

The testing itself may be valuable, but the customer experience needs significant improvement—especially for members with irregular cycles. This common situation was clearly an after thought. A clear SOP for these cases and better continuity between support agents would make a huge difference.

Decent UX with exceptions

You guys need to add push notification alerts as new markers come in. This is a no brainer. Second, when clicking into a marker than navigating back, the scroll state of the list resets to the top. Suggest preserving your last scroll position from the scrollable list view. Suggest adding placeholders among the data list for markers that were ordered but not yet arrived (you can grey them out or something). Or have a separate list for what’s to come, vs me having to go into Visit 1 or 2 to see.

Love being about to get this info

You don’t have to beg your doctor for certain labs. Get performed what you think is necessary and the walk through and personalized feedback is invaluable. I think the price for this is an absolute steal.

Not Working...Revised

This app was great until it quit working. I open it up and it quickly just turns into a black screen that I can't do anything with.

Edit: Adjusting my rating. Customer service has been on top of it. Fantastic customer service!

Scheduling/calendar for women is GARBAGE

The scheduling ability for menstruating women is awful. Some tests have to be scheduled within certain number of days of the beginning of the menstrual cycle but function will block it off, eg. my period starts on the 10th I have to schedule a test on day 2-4 of my cycle but functions scheduling calendar will not allow me to schedule until the 18th. That’s not how math works, 2-4 days after the 10th is the 12th-14th. Other tests have to be scheduled within 19-21 days of the last period but I can’t put that my period started on the 10th if it’s the 11th. To make things worse, you can’t call them you have to go back and forth with their chat agents and you spend hours trying to get tests scheduled. I spent an entire day trying to get scheduled but at a certain point the chat agent stopped responding I’m guessing it was the end of their day. Eventually I just “tricked” the calendar to schedule a test understanding the limitations but I don’t even know if I’m scheduled for the right tests which is concerning considering the cost of all the additional tests. At this point it’s not worth the money and after this year I’ll be going to my primary care doctor for tests. Their scheduling ability is GARBAGE!

Great app

The AI app provides instant Information and helpful protocols

Rating pending.

Just discovered I was billed a second year without my consent. Love the app and very helpful. Able to get my MD to order the labs now that I know more. No need for more Function. Have contacted billing dept and waiting for refund. Will be happy to update my review when I hear back.

Black screen

For the last few weeks, this app has been buggy. Please fix. Used to work well without issue so maybe revert back to previous version.

Improvement

This app is slowly improving over the last year. I’ve been using. It would like prompts like once a day it asking you how stressed you are how well you slept things like that that could give ongoing trends without being intrusive love that it integrate with wearables looking forward to seeing how it pulls all this data together.
