Practical, real-food guidance to help reduce your kidney stone risk.
Track oxalate, calcium, sodium, and hydration in the foods you actually eat — and build habits that protect your kidneys.
Kidney Stone Prevention Diet is designed for anyone who has had a kidney stone, is at risk of forming one, or just wants to protect their long-term kidney health. Kidney stones are painful, disruptive, and expensive — and diet is one of the biggest factors people can actually control.
The app focuses on the four dietary levers that matter most for the majority of stone types: oxalate, calcium, sodium, and hydration. Instead of generic diet advice, it gives you a working knowledge of the real foods on your plate — how much oxalate is in that spinach salad, whether your dairy intake supports the calcium-oxalate balance, and how much sodium is hiding in that meal you thought was healthy.
It's built for practical, day-to-day use. You don't have to memorize charts or dig through medical papers. You look up a food, log a meal, or explore preventive strategies specific to your stone type — including calcium oxalate, calcium phosphate, uric acid, struvite, and cystine stones — and get clear, evidence-informed guidance in return.
Kidney Stone Prevention Diet is different because it centers the calcium-oxalate paradox that trips up so many patients: cutting calcium doesn't help — pairing calcium with oxalate-containing meals does. That subtlety is baked into every recommendation. It also emphasizes hydration and sodium reduction, which are just as important as any single food.
The app pairs beautifully with our free Learning Center, which contains detailed articles on every stone type, food categories, hydration strategies, and dietary myths. Where the Learning Center provides depth, the app provides day-to-day tools you can use.
It is not a replacement for medical care. It's a companion — a set of tools and guidance you use alongside your urologist, nephrologist, or primary care provider to make consistent, informed decisions about your diet.
Everything included, built for real everyday use.
Look up common foods and see oxalate, calcium, sodium, and hydration relevance at a glance.
Track daily fluid intake against evidence-based targets for stone prevention.
Build meals that pair calcium with oxalate-containing foods to reduce stone risk.
Guidance tailored to calcium oxalate, calcium phosphate, uric acid, struvite, and cystine stones.
Recommendations drawn from established urology and nephrology guidance.
Small, repeatable habits — hydration, sodium reduction, calcium timing — that add up.
Use it at home, at restaurants, at the store — web, iPhone, and Android.
Focus on lifestyle changes that support kidney health over years, not just weeks.
Three simple steps to get real value from day one.
Learn what dietary factors matter most for your specific stone type.
Use the app to check foods, pair calcium and oxalate correctly, and cut hidden sodium.
Hit your daily fluid targets consistently — the single biggest lever for prevention.
Everything you need to know before you download.
Anyone who has had a kidney stone, is at risk of forming one, or wants to support long-term kidney health through diet.
No. It is a companion tool for daily decisions. Follow your doctor's advice for medical care and testing.
Calcium oxalate, calcium phosphate, uric acid, struvite, and cystine stones.
No — that's a common misconception. Adequate dietary calcium actually helps by binding oxalate in the gut. The app helps you get calcium timing right.
It is the single biggest dietary lever for most stone types. The app helps you hit consistent daily fluid targets.
Yes. High sodium increases urinary calcium and stone risk. The app highlights hidden sodium and suggests swaps.
Yes — including high-oxalate foods, low-oxalate alternatives, and how to pair oxalate foods with calcium.
Yes — it's mobile-first and quick to check foods on the go.
A free tier is available. Advanced features may require a paid plan.
Yes — iPhone, iPad, Android phones, and tablets, plus the full web app.
