### 1/5 — App is messed up

*2021-08-10*

I just downloaded the app and it won’t even let me get through it. I was planning on making a purchase so when I was asked the question if I had made one yet, I chose the button for no purchase yet. The next screen says it’s going to ask me a couple questions. One of the questions asks for my zip code (along with height, weight, etc) but then I get the below message, before I can continue any further:

“looks like we don’t have data…enter another zip code here”

What is that supposed to mean? It asks for my home zip code - if it won’t accept my home zip code, what else am I supposed to enter? I don’t live anywhere else. Does this mean they don’t ship to my zip code then? Something’s off.

### 5/5 — Easy to use and useful information.

*2021-05-06*

I appreciate the immunity score and the ease of including my health information. Great recommendations on ways to increase immune strength and so convenient that it’s available with the d.velop vitamins.

### 5/5 — Love it!

*2021-04-29*

A simple app with a really unique way to represent an immunity score. Love that I have free access to registered dietitians whenever I need them! And their vitamin D is a solid product.
