Our transparent provision of an expansive set of research-backed nutritional data will help users keep track of their purine diet and promote a healthier gout diet.

Purity provides the following features:

• Research-backed purine data from an expansive selection of food items

My name is Ariana Pineda, and I am a high school student with a deep interest in the intersection of medical research and technology. I developed this app as a tool to help my father and a few of my relatives who suffer from gout. I hope this app will help others manage and monitor their purine intake. Please feel free to provide constructive feedback about this app. I will make further improvements in future versions.
