Dietary advice for gout or kidney stones is often conflicting, inaccurate or even completely outdated. Our app OxiPur contains only the most recent information available on these topics. We analyzed hundreds of scientific studies and summarized the results in helpful notes.

Additionally, you can use the app to create and evaluate your own recipes or track your daily intake with the food diary. You won't find any other resource that offers such a wealth of information in one place. Our app is the perfect tool to improve your eating habits and get your health back!

OxiPur covers the following topics:

■ Diet and Gout
Even today, the main treatment of gout still focuses too much on avoiding purines, although they are only part of the problem. Our app uses a wider approach and includes additional important factors like alcohol, fructose, and sodium. You can also combine different dietary profiles (e.g. low glycemic index) as needed.

■ Low Oxalate Diet
Without proper instruction a low oxalate diet is very complicated to follow. Our app knows the oxalate content of about a thousand foods and helps you plan your meals. It also considers the bioavailability of oxalates as well as other factors that play a role in renal problems like the formation of kidney stones.

You can use the app for free with a limited functionality. It doesn't require a registration and is free of ads. If you want more details, there are two separate one-time in-app purchases that upgrade each topic with additional features and information.

Pro (Paid) Versions Worth The Info

I bought this today and quickly saw that the app organizes the foods and classifies their effects on gout (uric acid) & kidney stones (oxalates) very clearly.

If you suffer from these like me, you will want to pay to enable the Pro versions, which gives you the detailed impacts of the foods. You can open the gout pro and/or kidney stone pro levels separately, each for ~$10. I bought both since I suffer from both occasionally. I found $20 a small price to pay for having such a valuable resource at my fingertips in my pocket! You might feel differently, but the developer definitely did the homework for us - no more google searches for good & bad foods! 😁

I often have gout attacks that last up to 4 weeks as well as Kidney disease. I am disciplined enough to eat right. The problem is i like a huge variety foods and it’s very difficult to conveniently get the information quickly. Not only is this APP quick, it’s also concise. Everything about the food item im looking up on one page rather than going back & fourth. This app works especially nice for me considering i’m on not only a Gout diet but also a strict Kidney & Cardio diet.
I have downloaded and purchased almost all the other APPs pertaining to this and nothing compares.
The BEST by far.
Thank you,
John C

Could be very useful

This could be a great app. I’ve found it useful for keeping track of daily oxalate count. BUT, I’ve also found that it conflicts quite often with the Harvard Study, which has long been the gold standard relative to oxalates in food. The other thing that is really maddening is that the only units available are ounces, or grams. It would really be helpful if the unit choices included things like fluid ounces and cups. Many foods are listed relative to the quantities, not weight, but this app requires the conversion to properly determine oxalate values. It’s really not that convenient to use, but proves more comprehensive information (though some of it appears to be incorrect) than any other source. I would like to know the sources for some of the information.
