Overall the free version of the OxiPur app enables individuals to understand which foods are suitable for patients with gout and/or kidney stones and adjust their diet accordingly.

The free version of the OxiPur app offers simple diet tips for people with gout or kidney stones who want to follow a low-purine or low-oxalate diet. It includes a food database with over 1,200 items, each labeled with a color-coded system based on their purine and oxalate levels.
Users can track what they eat using a food diary (up to 5 entries per day) and create up to 5 custom recipes. The app then estimates their intake of purines, oxalates, and other nutrients.
The app also has educational content about gout, kidney stones, and includes a blog for more information.

Note: The free version has limited content. The PRO version unlocks more nutritional information.
