Kidney eGFR Tracker

Take charge of your kidney health in one private, offline app. Kidney eGFR Tracker lets you record your lab results and instantly see your estimated GFR (eGFR) using the published CKD-EPI 2021 equation, shown next to the KDIGO reference ranges so you always understand where your latest numbers sit. From early CKD to dialysis and transplant follow-up, keep every lab, medication, and vital in one organized place — and walk into each clinic visit prepared.

Everything stays on your phone. There are no accounts and no cloud — your health data never leaves your device unless you choose to export it.

KEY FEATURES:
• eGFR from your labs — enter creatinine, age and sex; the app computes your eGFR with the CKD-EPI 2021 formula and shows your KDIGO CKD stage (G1–G5)
• Lab tracking — record creatinine, ACR (mg/g or mg/mmol) and other kidney labs over time, with your eGFR charted against the KDIGO stage bands
• eGFR trends & slope — visual charts of your eGFR and creatinine over time, so you and your nephrologist can see the direction of change
• Dialysis log — record hemodialysis/peritoneal sessions and set a recurring dialysis schedule
• Medication manager — keep your renal medication list and track what you've taken
• Vitals tracking — log blood pressure, weight, and daily fluid intake
• Renal diet & potassium — log foods and keep an eye on potassium and other nutrient intake
• Transplant tracker — record transplant-workup notes and milestones (premium)
• Nephrologist reports — export your lab results as a clean PDF report or CSV to share at appointments
• Smart reminders — optional reminders for medications, lab cadence, dialysis, blood pressure, and fluids
• Trends dashboard — your CKD stage, latest labs, and key numbers at a glance

IMPORTANT MEDICAL DISCLAIMER: Kidney eGFR Tracker is a personal log and educational organizer — not a medical device and not a substitute for professional care. It computes eGFR from the values you enter and displays them against published reference ranges for information only. It does not diagnose, treat, monitor, or give medical advice, and the CKD stage shown is a reference classification, not a diagnosis. Always consult your nephrologist or qualified healthcare provider for medical decisions.

Start tracking your kidney health today and keep your numbers organized for every visit.
