### 5/5 — Shrimp Scampi

*2026-07-24*

So I went to a local grocery store and was going to purchase frozen shrimp scampi.  So, I scanned the package with what 
2know and I learned that there were 39 ingredients mixed in with the shrimp.  I immediately placed the package back in the frozen section. Later that day. I went to a large box store and bought fresh shrimp that had no additives. So glad this tool is now available so that I can make better choices.

### 5/5 — Was Wishing for This Just a Few Days Ago

*2026-07-11*

My dog is allergic to some ingredients, and I was searching for another dog food that avoided those, in the grocery store. It was a hassle to pull down the bags and find the ingredients. 
Next time, I will use the What2Know app!

### 5/5 — How did I survive without this?

*2026-07-11*

This app is so helpful for knowing what food and consumable products are safe for my family and me. It’s easy to use and keeps your history. It lets you put in your family information, as well as your other people (dogs and cats).

### 5/5 — Superior to other scan apps

*2026-07-10*

With this app you can scan food, cosmetics, pet foods and more for “What2Know” about every consumable. You can enter your family and pet information so it knows each persons and each pets dietary preferences and restrictions. It’s other scan apps on steroids!
