Track Every Nutrient Your Kidneys Care About
Sodium. Potassium. Phosphorus. Oxalate. One app tracks all four — with limits personalized to your condition.
Why Managing a Renal Diet Is So Hard
Kidney patients don't just watch one number. They juggle four nutrients across every meal, every day. Existing tools weren't built for this.
Juggling Multiple Trackers
Most apps track one nutrient. CKD patients need to watch four. We unified them into a single dashboard.
Generic Limits Don't Fit
Your nephrologist says 2,000mg sodium. Generic apps say 2,300mg. We listen to your doctor, not population averages.
No Idea What's In Restaurant Food
We've analyzed 1,600+ dishes at 50+ chains — with sodium, potassium, and phosphorus estimates alongside oxalate.
How It Works
Set Your Condition
Tell us about your health. CKD? Dialysis? Post-bariatric? We set personalized nutrient limits based on clinical guidelines.
Log Your Food
Search 2,500+ foods, scan barcodes, or snap restaurant menus. We calculate all four nutrients instantly.
Watch Your Rings
Four concentric rings show your daily progress. Stay in the green. Your kidneys will thank you.
Built for People Who Need It Most
Different conditions, different limits. OxalateGuard adapts to your specific renal health needs.
CKD Stage 3-5
Your nephrologist said watch sodium and phosphorus. We track both — plus potassium and oxalate — with limits calibrated to your CKD stage.
Dialysis
Pre-dialysis nutrient management in your pocket. Know exactly what you're consuming between sessions so you arrive prepared.
Kidney Stone Formers
The oxalate tracker you know and love — now with the full renal picture. See how sodium and hydration affect your stone risk.
Heart Failure
Sodium restriction is critical. See exactly where you stand meal by meal, with a dashboard designed for daily limits.
Data You Can Trust
Our nutrient data comes from established, peer-reviewed sources. We don't guess. We reference.
15+ Peer-Reviewed Sources
Oxalate data from Harvard, Wake Forest, and international research databases.
USDA FoodData Central
Sodium, potassium, and phosphorus from the gold-standard U.S. nutrient database.
Consensus Algorithm
When sources disagree, our algorithm identifies outliers and computes reliable values.
