Take control of your kidney diet — and know exactly how you're doing, every day. KiddiAI is built around a daily Renal Balance Score (RBS) — a personalized 0–100 rating across protein, sodium, potassium, phosphorus, and fluid, tailored to your CKD stage. YOUR DAILY RENAL BALANCE SCORE The RBS combines your intake across all five kidney-critical nutrients into a single score, personalized to your CKD stage (1–5), dialysis type (hemodialysis or peritoneal dialysis), and any additional restrictions like fluid or sodium limits. Four tiers tell you exactly where you stand: • Optimal — keep it up • Stable — good, with room to improve • Caution — adjust today's choices • Alert — review your intake today Watch your 3-day trend to see if you're improving over time. Hit Optimal? Celebrate with confetti. 3-DAY DIET ANALYSIS Get an AI-powered summary of your eating patterns across the last 3 days — with specific observations and suggestions tailored to your kidney diet profile. FOOD JOURNAL THAT WORKS FOR YOUR KIDNEYS Unlike general food trackers, KiddiAI tracks the nutrients that actually matter for kidney disease. Your food journal is organized by meal type (breakfast, lunch, dinner, snacks), with dietary tags so you can instantly see which foods are high or low in the nutrients that matter. • Search thousands of foods from the USDA FoodData Central database • Barcode scanning for packaged foods • Voice input — just say what you ate • Recently logged foods for fast repeat entries • Kidney Safety Indicator — every food shows a color-coded label (Safe / Caution / Avoid) based on CKD-relevant nutrients • Quick fluid logging — add water from the dashboard or journal in one tap AI FOOD ANALYSIS Not sure what's in your meal? Snap a photo. KiddiAI uses advanced AI to identify foods and estimate their nutritional content — including potassium, phosphorus, and sodium — so you can log complex or restaurant meals without guessing. BUILT FOR YOUR KIDNEY CONDITION KiddiAI adapts to your specific situation: • CKD stages 1 through 5 • Hemodialysis and peritoneal dialysis • Fluid restriction (CHF / edema) • Kidney stone prevention diet • Custom nutrient limits set by your care team Set your profile once. Every score, tip, and limit adjusts automatically. DAILY DIET ADVICE Each day, KiddiAI surfaces personalized diet tips matched to your CKD profile — covering potassium, phosphorus, protein, sodium, and fluid management. Practical, kidney-specific guidance, not generic nutrition advice. STAY MOTIVATED • Logging streak — track your current and longest consecutive days • Meal reminders — set customizable post-meal nudges for breakfast, lunch, and dinner • Nutrient progress rings and calorie visualization • 3-day RBS trend view 1 MONTH FREE TRIAL Try every feature free for 1 month. No commitment required. After the trial, a subscription keeps all premium features — food logging, AI analysis, and your full score history — available without limits. KiddiAI is a dietary tracking tool and is not a substitute for medical advice. Always follow the guidance of your nephrologist or registered renal dietitian.

WHAT YOU CAN LOG - Lab values: eGFR, creatinine, BUN, albumin, phosphorus, potassium, calcium, hemoglobin, hematocrit, iPTH, urine ACR, proteinuria. - Blood pressure morning and evening, with trends across weeks and months. - Dialysis sessions including pre and post weight, dry weight, UF target, run time, vascular access notes. - Fluid intake tracking with daily limits and reminders. - Medications including phosphate binders, ESAs, vitamin D analogs, ACE inhibitors and ARBs, diuretics, iron and renal vitamins. - Diet log focused on potassium, phosphorus, sodium and protein. - Symptoms: fatigue, swelling, itching, sleep, appetite, nausea, restless legs.

WHY CKD TRACKER Generic health apps do not understand CKD. They miss the labs, miss the diet rules, miss the dialysis rhythm. CKD Tracker is purpose built for kidney care. The eGFR trend, the phosphorus and potassium budget, the dialysis session log, the BP target, the fluid limit. Every screen reflects how kidney patients and renal teams actually work. IMPORTANT This app is for informational tracking only. It is not medical advice and does not diagnose, treat, or prescribe. Always consult a qualified healthcare professional, including your nephrologist and renal dietitian, before starting, changing or stopping any treatment, medication, dialysis schedule or diet plan.
