About this app

Kidney Guardian is a specialized diet management app meticulously designed for individuals managing Chronic Kidney Disease (CKD).
Stop worrying about complex nutritional calculations—let Kidney Guardian help you make safe and healthy food choices every day.

We focus strictly on the four most critical nutrients for kidney health: Sodium, Potassium, Phosphorus, and Protein.
With intuitive tools and a clean design, Kidney Guardian makes tracking your daily intake effortless.

All nutritional data and charts are strictly ordered by clinical priority: Sodium, Potassium, Phosphorus, and Protein.

As you drag the slider, a real-time mini dashboard instantly shows your daily total progress for the four key nutrients.
