Overall, the free version of the OxiPur app helps you understand which foods are suitable for patients with gout and/or kidney stones so you can adjust your 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.
You can track what you eat using a food diary (up to 5 entries per day) and create up to 5 custom recipes. The app then estimates your intake of purines, oxalates, and other nutrients.
The app also has educational content about gout and kidney stones, and includes a blog for more information.

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

Clinical review

Reviewer: Johanna Lim, Clinical Pharmacist (Cardiology Expert), Health NZ Te Whatu Ora Te Matau a Māui Hawke’s Bay
Date of review: July 2025
Platform: Apple
Version: 4.2 This review is based on the free version of the app.
Comments: Overall, the free version of the OxiPur app enables you to understand which foods are suitable for patients with gout and/or kidney stones and adjust your diet accordingly. This app is easy to use and provides educational content and a link to a blog. However, features are limited in the free version – the PRO version unlocks more nutritional information. The information in this app is not intended to replace information and treatment advice provided by healthcare professionals.
Safety concerns: None.
New Zealand relevance: The primary focus of the app is on food and a breakdown of its content. It doesn't consider the role of genetics. For example, most Māori and Pacific Peoples have genes that stop their kidneys getting rid of uric acid in their urine.
