### 5/5 — No data collection with this app

I love this app! So easy when I go to the grocery store. I have a grandson with severe tree nut allergies. These day there are so many thing that are made with or processed with tree nuts. I can’t keep track of what does and doesn’t have them. I would rather be safe than sorry. I do not ever want to accidentally buy something that would give him an allergic reaction.

### 5/5 — Exceptional

*2025-05-21*

If you or anyone you know has food or skin allergies, look no further, this is THE app to have! It is the best one out there to help identify allergens in products, or really anything you want to avoid or even include! 

It is quick, efficient, and easy to use! It works even when you don’t have internet access, which can be super helpful in some stores. I never get reception in Walmart. I even use it for my dog food to make sure the flavor I’m buying doesn’t have chicken. 

The monthly subscription is extremely affordable and helps give me peace of mind in identifying allergens in products!

Thank you Allergen Hound for making shopping easier!
