Track eGFR, creatinine, blood pressure, dialysis sessions, lab results, medications, fluid intake and daily symptoms in one calm, organized journal.

Download CKD Tracker free of charge. 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 tracker: log each session's pre and post weight, dry weight, UF target, run time, and 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. - Renal diet log focused on potassium, phosphorus, sodium and protein. - Symptoms: fatigue, swelling, itching, sleep, appetite, nausea, restless legs.

APPLE ECOSYSTEM - Apple Watch logging for quick BP and symptom entries. - Home screen widget for today's tasks and recent eGFR. - iPhone and iPad with optional encrypted iCloud sync. PRIVATE BY DEFAULT Your data stays on your device. No forced account. Optional iCloud sync is private to you. Nothing is sold, nothing is shared, nothing is mined. BUILT FOR - People with CKD stages 1 through 5 who want a kidney pal to keep their numbers in one organized log. - Hemodialysis and peritoneal dialysis patients tracking sessions and dry weight. - Kidney transplant recipients tracking immunosuppressant doses, labs and rejection markers. - Caregivers helping a parent or partner manage CKD. - Renal dietitians and nephrology teams who want a clean shared journal. WHY CKD TRACKER Generic health apps do not understand CKD. They miss the labs, miss the diet rules, miss the dialysis rhythm. The CKD Tracker app is purpose built for kidney care to help you organize your kidney health records. 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.
