OxiPur was developed specifically for people with gout or kidney stones and helps you follow a low-purine or low-oxalate diet. Beyond that, the app can be adapted to many other dietary needs, such as a low-sodium diet for high blood pressure or a low-carb diet. You can combine the different diet profiles in any way you like.

OxiPur is available in German and English. In addition, you can display the names of all foods in Spanish, French and Dutch, which is especially handy when shopping on vacation or abroad.

All values in OxiPur have been carefully compiled from scientific studies and international food databases. The sources used are fully listed in the app, so you can always see what the information is based on.

Many websites and apps look only at purine or oxalate content and overlook the fact that numerous other factors can influence the course of the condition, for better or worse. OxiPur takes several relevant factors into account at the same time – for gout, for example, whether the purines are of animal or plant origin, as well as the fructose, alcohol and salt content. Detailed notes on the most important foods provide additional guidance.

The "strong oxalate reduction" profile severely restricts oxalate intake and is intended for short-term use, for example during an acute phase. The "moderate oxalate reduction" profile provides a moderate reduction and is better suited to long-term use, as it allows a more balanced choice of foods and thus reduces the risk of nutrient deficiencies.

In addition to the profiles for a low-purine and low-oxalate diet, the PRO packages offer further profiles: high blood pressure, healthy fats, low glycemic load, low-carb diet and unprocessed foods. You can combine all profiles as you wish.
